Many want to build a 2017 gaming PC within a small budget. But this is a very difficult matter, because the cost of computer components increases every year, as well as the requirements of games regarding PC performance. At the same time, I would like to assemble a computer, the filling of which will remain relevant for at least several more years, because it is unprofitable to invest in its modernization every year, and not everyone can afford it. In our material, you will find out what details are most important in games and how to assemble an inexpensive gaming computer.

Putting together a 2019 gaming computer do it yourself

CPU

The first step is to decide on the choice of the processor - the most important element of the computer, which is responsible for all computing processes. You have to choose between the products of two world famous brands Intel and AMD. It is recommended to find performance tests on the Internet and compare the results with each other. The best choice in our opinion is the Intel core i5 processor - its power is enough for any games and fast operation of the operating system.

The higher the processor generation, the better the performance, keep this in mind when choosing. To build a powerful budget gaming computer, you can use the i5 7500 - practically the most top-end solution in the lineup, which perfectly copes with resource-intensive tasks. Of course Intel processors core i7s will be better, but the performance gains are not as big as the overpayment. AMD Athlon II X4 640 will be an excellent solution for assembling a budget computer, although its capabilities are inferior to solutions from Intel.

Choosing a motherboard

You need to find a motherboard that will support the format of the selected processor. When choosing it, you need to pay attention to the processor socket (for example, an LGA 1151 socket is required to connect an Intel i5). Also important is the standard of slots for RAM, their number and frequency. There may be additional connectors, which is worth paying attention to in order to choose a motherboard with suitable functionality.

RAM

When assembling a gaming computer in 2017, the optimal solution will be DD4 standard RAM with a volume of 8 or 16 GB. There is simply no need for more volume, and so everything will fly. But 4 GB will not be enough for modern games, especially since part of the memory is consumed by the system. Volume random access memory you need to choose based on your budget - the more you put it, the faster games will load and the interface will work smoother. But keep in mind that if in the future you have a desire to expand the volume, then you need to install a bar with a similar frequency and preferably from the same manufacturer, otherwise it may turn out to be incompatible. It is better to choose memory with the maximum frequency, its performance largely depends on this. When deciding how to build an inexpensive 2017 gaming computer, you need to make sure that the chosen RAM standard is supported motherboard.

Please note that if you install the RAM bar by more than 3 GB, then the operating system must have a 64-bit architecture. Otherwise, how many memory you install, but no more than three will be available.

The graphics card is the most important part when assembling a gaming computer

The question of how to build a good gaming computer is impossible to imagine without choosing a video card that is responsible for processing graphics in games. The graphics card and processor are the most expensive parts on which gaming performance depends the most. When choosing, it is better to read the reviews, since manufacturers offer a huge variety of models that vary greatly in their capabilities. For a budget PC, an Nvidia Geforce 1050 Ti with 4GB of storage will suffice. But recently, with video cards, not everything is so simple - they are being bought up by miners, and if they can be found on sale, then it costs much more than it should. This applies to the entire video card market. If you have a large budget, then you should pay attention to the Nvidia Geforce 1060, 1070 and 1080 cards - the top solutions for today, buying which you will get maximum performance.

When deciding how to assemble a gaming computer yourself, you can pay attention to cheaper solutions from ATI or Nvidia. When choosing, consider the connector to which the video card is connected. DDR5 is the leader - this is the latest format that is used in almost all motherboards. Therefore, it is better to opt for it, DDR3 will become less and less popular over time until it dies out completely. And remember that a higher model number does not always mean that it is better. You need to look at reviews and comparison of performance tests on special sites.

Drive selection

The best option today is to use an SSD drive in tandem with a standard one. The system is installed on the first, which gives a tangible increase in productivity. But due to the high cost, it will be unprofitable to buy a large SSD, which means that over time you will no longer be able to store all the files on it.

Here the standard saves HDD, which is much cheaper. So, for 3000-4000 rubles you can buy a 1 TB hard drive, while for the same amount you can find a 128 GB SSD. Again, when deciding how to build a good gaming computer inexpensively 2017, you should read reviews and pay attention to such characteristics as rotational speed. It must be at least 7200 rpm. The speed of writing and reading data depends on this parameter. A fast storage device helps you launch games faster and also shortens installation times.

Power Supply

Thinking about how to assemble a gaming computer 2017 yourself, you need to calculate the required power of the power supply. To do this, you need to look in the characteristics of how much energy each computer part consumes, add up the amount and add about 20% just in case. Most PSUs come with 20 or 24 pin connectors, please note these are compatible with your motherboard. You should not take the power supply complete with the case. As a rule, it is not of high quality. For a gaming computer, you will need a version with a power of at least 500 watts.

Frame

The case should not only be beautiful, but also contain all the connectors you need to use. Particular attention should be paid to cooling, because even on the most powerful hardware, games will slow down if it overheats. Some cases have 80mm fans, others have 120mm fans. The top solution is a liquid cooling system, but it is unreasonably expensive, so it is better to opt for a case with 3-4 powerful coolers. The more powerful the filling, the more efficient the cooling system should be.

Let us first decide on the amount of the budget for the PC to be collected, and also clarify that this budget applies to what will be located in the system unit - this amount does not take into account the monitor, keyboard and mouse, since these components are the subject of a separate conversation.

And in this article, speaking about an inexpensive computer, we mean a budget for assembling a PC "from scratch" no more than 30,000 rubles. To assemble, we need the following components:

  • CPU;
  • Motherboard;
  • HDD;
  • System case with power supply;
  • Video card;
  • Optical drive for CD / DVD discs.

Microprocessor selection

The computer processor is the main center of the computing capabilities of the computer, and recently the graphics core was also transferred to its substrate, so the assembly can exist without an external video card. However, in our case we are talking about a powerful PC, so we need an external video card.

The choice of processor will determine the underlying platform of our PC. Today, the most popular platforms are Intel and AMD. The assembly will be carried out on the basis of the Intel platform, since the processors of the computer giant Intel are considered more efficient and economical, although they are inferior in graphics capabilities to their AMD counterparts.

It is not worth saving on a microprocessor, since we want a powerful computer. Also, we will provide for the purchase of a boxed version of the microprocessor, which is supplied with the heat sink assembly. Our choice will focus on a microprocessor with an LGA 1150 socket, which is by far the most common. The cost of this component should not exceed $ 100, and therefore a good solution in this case it will become Pentium G3220 or G3240... Its cost will not even be higher than $ 90.

Motherboard

What we should save on is when choosing a motherboard, but even here the savings should be within reasonable limits. By choosing a microprocessor, we have significantly narrowed the options for choosing a motherboard, since now we need to choose only from those provided by the LGA 1150 socket.

The savings in choosing a motherboard concerns its layout. We don’t need to buy a motherboard equipped with connectors that will never be used - for example, RAID arrays. And the more connectors and “wider” the wiring, the more expensive the motherboard is. For our needs, it is enough that the motherboard has USB, SATA connectors and one PCI-Express for connecting a video card. In addition, almost all modern solutions have a built-in LAN port and VGA connector. In our budget case, you shouldn't choose from a full-size ATX, but mATX is fine. Let's stop our choice on motherboard from GigaByte is the GA-B85M-D2V board... Its cost is about $ 80, and therefore we have already spent $ 170. Its connectors and ports are enough not only to connect the internal components of a PC, but also to connect all the necessary computer peripherals.

The motherboard we have chosen has two slots for DIMM DDR3 memory sticks. At the same time, the supported frequency is 1333-1600 MHz, and the memory capacity is up to 16 GB. In our case, at first, 4 GB will be enough - we will fill only one slot. It is necessary, however, to understand that in 32-bit Windows the user will have access to a little less than 4 "gigs". Less memory cannot put a modern PC in the category of powerful ones, since the same operating environment Windows 8 (64-bit version) already requires 2 GB of memory, and modern applications are also very demanding in this matter. Therefore, our choice will be made on Kingston DDR3 4Gb 1600 MHz memory... Its cost is about $ 50, and therefore the total amount of our purchase has already reached $ 220.

Video card

This is the component on which it is also not worth saving, since it is the video card that is responsible for the formation and display of computer graphics. The higher the memory capacity of the graphics card, the higher the monitor resolution your PC can support, and the higher its bit depth, the faster graphics can be generated and displayed. In our case, we need a budget version with a 64-bit bus width and 2 GB GDDR3 memory. Let's opt for a video card from the company Sapphire worth $ 80. In the future, it can be easily replaced with a more powerful one. Thus, the total amount of our purchase rises to $ 300, and we still have to choose a system unit, an optical drive and a hard drive.

HDD

Now we do not need to purchase external hard drives in bulk, we need an internal HDD - we will opt for a classic hard drive and will not consider solid-state drives. The most common average hard disk space available today is 500 GB, but some terabytes are only $ 10 more expensive. If you come across an IDE interface, then we skip such a HDD, and pay attention to the SATA interface. In our case, for example, hard from Western Digital WD10EZEX... The volume of this HDD is 1 TB, and the spindle speed is 7200 rpm. Also, it has 64 MB cache and SATA 3 interface, which is supported by our motherboard. The cost of the hard one we chose is about $ 85, so our total purchase amounts to $ 385.

System unit

To combine all the purchased components, we need an inexpensive system unit with a 400 W power supply - this power is enough to service the purchased components. Since we chose a motherboard of the micro-ATX form factor, it is enough for us that this case supports motherboards of this particular form factor. But in the future, the user of the computer may wish to upgrade it, and therefore we will choose a case that also supports motherboards of full-size ATX form factor. In this case, a case, for example, from Logicpower with a built-in power supply for $ 30 is perfect. Thus, our amount increased to $ 415.

Optical drive

For full-fledged work, we will need an inexpensive optical drive that can play the contents of CDs and DVDs. We'll need a SATA drive that costs less than $ 25.

Our purchase did not exceed $ 500, however, we assembled a sufficiently powerful computer with good technical performance and with the possibility of its further modernization. The motherboard, for example, allows you to add another memory strip and a number of expansion cards. The video card can be replaced with a more powerful one, and the case supports the possibility of replacing the motherboard itself with its full-size ATX version. In addition, it will be possible to improve the cooling system in the case by installing an additional case cooler. At the same time, we have invested less than $ 450-500. It should also be taken into account that you will have to spend money on two data cables for hard disk and an optical drive, but their cost is incomparably less than the amount spent on assembly.

More and more people are wondering every day how to assemble a computer yourself from components from scratch. Assembling a computer on your own and with your own hands is a rather exciting and educational process. Self-assembly and customization of a computer costs on average 30% less than buying an already assembled, ready-to-use machine.

Some people mean a computer system unit, but I hasten to remind you that a system unit without a monitor, keyboard and mouse is useless. Only with these peripherals does it become a fully functional personal computer.

What do you need to assemble a computer?

To start the assembly, you need to pick up a new set of parts. It is undesirable to buy parts that were in use, since in the absence of experience in setting up a PC, difficulties may arise.

So what does it take to build a computer? The points:

  1. computer case,
  2. power unit,
  3. motherboard,
  4. CPU,
  5. RAM,
  6. video card,
  7. sound card,
  8. DVD drive,
  9. HDD,
  10. monitor,
  11. keyboard,
  12. computer mouse.

How to choose a case for your computer?

Choose a solid computer case. It is necessary to pay attention to the fact that in stores there are Chinese-made cases, which are made of very thin sheet metal and are easily deformed under mechanical stress.

The computer chassis includes a power supply and network cable... Sometimes the case and power supply are sold separately.

How to choose a motherboard?

Motherboards come with integrated video and sound processing cards. These motherboards are easier to assemble and have average specifications.

If you need to equip your computer with more powerful means of playing sound and video information, then you need to use a motherboard, which is equipped with slots for a video card and a sound card.

When choosing a motherboard, it is necessary to determine the area of ​​primary use of the computer.

How to choose a video card?

It makes no sense to use an expensive video card to watch news and video information on the Internet. But if you are an amateur computer games with cool video effects or are planning to work in powerful video editing programs, then you cannot do without a good video card.

When choosing, always start from the purpose for which you are purchasing a video card. The power and price of the video card will depend on this.

Tell the store clerk why you need a video card. He will be able to help you find the right model.

How to choose a sound card?

The question of how to choose the right sound card is quite extensive, so I will limit myself to basic theses.

Sound cards integrated into the motherboard generally have two channels. If you are planning to listen to music through an amplifier or receiver, then buy a multi-channel sound card. There are some that support 5.1 and 7.1 sound systems when there are multiple speakers and a subwoofer in the system.

Sound cards are internal, which are inserted into a connector on the motherboard, and external, which can be connected to a computer via a USB or Firewire connector. Although the latter are more professional-level sound cards used by sound engineers, DJs and electronic musicians.

First of all, in order to answer the question of how to choose a sound card, ask yourself a question, why do you need an audio card in principle, and then look for a model that meets your criteria.

How to choose RAM?

To buy a suitable RAM, you must first decide on its volume. For an ordinary modern computer, 4 GB is enough. For a gaming computer, you need at least 8 GB.

It is also important to know the type of RAM connectors on your motherboard. Recently, you can find mainly only DDR3, but in general you can find the following types of connectors:

The type of RAM connector is usually indicated in the description of the motherboard. In any case, check with the store if they can change the memory you buy for another type of memory of the same size, if you make a mistake with the choice of the memory type.

Memory cards are sensitive to static charges, so it is not recommended to unpack them and keep them open until installation. Before installation, it is recommended to touch the metal case in order to discharge any accumulated static charge on you.

HDD

The information that is on the hard drive also requires a certain amount of space. Depending on your goals, you may need additional storage space.

For work, a 500 GB hard drive is the best option. If you are going to play games or download movies in Blu-ray format to your hard drive, and there will be many of them, then you can safely take a hard drive of 1 terabyte or more. I prefer to go with Seagate Barracuda hard drives.

DVD drives

DVD drives differ by manufacturer and price, otherwise they are standard. Basically, they are needed to install programs and drivers for hardware at the initial stage of setting up a computer. Further, if you connect to high-speed Internet, most likely, you will rarely use your DVD drive.

How to choose a processor?

The processor power used to depend only on the clock frequency. The higher the frequency, the more powerful the processor. But now such a factor as the number of processor cores has been added. The more powerful the processor, the higher the speed of the computer. The motherboard must support the platform or socket of the processor of your choice. Therefore, it is better to choose them together and in advance.

The answer to the question of how to choose a processor depends, again, on what you are going to use the computer for.

Monitor, keyboard, mouse

I have had a Phillips widescreen monitor, a Logitech MX Performance Mouse wireless mouse and an ordinary USB keyboard for a long time and have been successfully working.

But I leave the choice of these peripherals to your personal taste. The number of opinions and options here is huge. I recommend using simple but reliable ones.

Do-it-yourself computer assembly: How to assemble a computer yourself?

Important tip:

When assembling the computer yourself, it is not recommended to wear synthetic clothes that condense an electrostatic charge. Electrostatic voltage is detrimental to microcircuits. Therefore, you should use cotton clothing.

So how do you build your own computer? Building a PC starts with installing the processor and heatsink with fan on the motherboard. The processor is installed in the socket and fixed with a lever. Thermal paste is evenly applied to the surface of the processor and the heatsink is fixed, as shown in the figure in the instructions. The fan cable connector must be plugged into the power socket located next to the processor panel.

You can immediately install the RAM card on the motherboard. It is necessary to be extremely careful and not make great mechanical efforts, so as not to damage the adjacent elements of the board. I already wrote detailed with pictures. A detailed description of how to install the processor is supplied with the motherboard.

The next step in the assembly is to install the hard disk and DVD drive into the PC case. Then the motherboard is installed and secured. The wires with connectors that go from the power supply must be connected to the corresponding sockets on the motherboard, DVD drive and hard disk. Then connect all the wires that go from the front panel of the computer case to the corresponding connectors on the motherboard, following the connection instructions.

Now you can proceed to installing the operating system. After full customization computer software, you can close the case cover.

In general, assembling a computer with your own hands takes place in this order. The nuances of how to independently assemble a computer are not deliberately described, since in each case they are different. Leave questions about assembling your computer in the comments.

3DNews has a large and varied audience. The resource is visited both by seasoned enthusiasts who have collected more than one PC, and by readers who are just beginning to delve into all the intricacies of computer technology. The test laboratory elegantly and overclocks them to serious frequencies, to study the durability of drives, in modern games and to purchase unusual hardware abroad, but at the same time it does not forget about inexperienced users. This is how the heading "" appeared, which offers various configurations of system units. After reading the comments and personal communication with the readers of the site, it became clear to me that it was time to tell in detail and show newcomers how to assemble the components proposed in the article into a single whole. This is what this material is about.

The proprietary software from the motherboard manufacturer will also come in handy. All companies complete their devices with such applications. And they have similar functionality. For example, in MSI program Command Center unlocked CPU and RAM overclocking features. And in the same software, the fan speed is adjusted and the temperatures of the CPU and chipset are monitored. The "Command Center" supports the installation of a large number of additional modules. For example, RGB Mystic Light Sync can be used to customize the backlight of the motherboard. Live Update Widget automatically downloads and installs the latest drivers, BIOS, and more software... The Gaming App utility gives access to the overclocking profile of the video card.

We ran the system in Prime95 for several hours, checked the computer in 3DMark, Heaven and in your favorite game and did not reveal any overheating, no artifacts, no crashes and freezes, we ran several benchmarks and compared the results with other data available on the Web - that's all, now you can be absolutely sure that your computer is fully operational 24/7.

⇡ Conclusions

Each user may have their own reasons to assemble the system unit on their own. Some do not want to overpay for work that they can do themselves. Others want complete control over the entire process: from the selection of components to assembly and system configuration. And for some, "digging" with iron is just a hobby. Whatever the motive, but the most difficult action when assembling system unit is the choice of components, and in this the 3DNews team is always trying to help its readers. If you have selected fully compatible components, then it will not be difficult to complete all the other steps for assembling a PC. Just approach this lesson as responsibly as possible, when working with iron, be careful and careful - you collect it for yourself. Then you will not have any problems either at the stage of assembly, or at the stage of software installation and testing.

Self-assembly of your own computer- this is a great opportunity to choose computer components in accordance with your individual requirements and preferences. In addition, this allows you to save a considerable amount of money and get exactly what you need, with all the necessary characteristics, without overpaying for assembly and without enriching once again large and not very large office equipment stores, often sinning by "stuffing" cheap components into an expensive fancy one. case and selling it at triple the price.

This article will take you step by step build your own computer, which will be maximally adapted to your personal needs.

Out-of-the-box desktops are often not configured to meet a specific customer's needs. It also happens that the computer on sale has a good configuration, but is overpriced in terms of cost. A ready-made computer can also suit you with almost everything, except for one component. This may not even be connected with the functional side of the computer, but with the aesthetic one. For example, you may not like the case of the system unit.

On the other hand, by carefully selecting each component of your system, you are not only free to choose components from different manufacturers, but also building a computer at a much lower cost. You don't have to worry about the warranty. This is an argument that many off-the-shelf computer sellers love to make in order to scare inexperienced buyers. By purchasing electronic components separately, you also get a warranty for each of them, and if any hardware problem occurs, you can easily fix it by replacing one or another component under warranty. However, I hasten to reassure you, such problems are quite rare, modern computer components are very reliable, so the probability of their failure is quite low. Further in the article, we will get acquainted with some technical information regarding individual components and manufacturers of computer components, it will help you in their selection and assembly of a computer with your own hands.

Choosing components for assembling a computer

The following are descriptions of the computer components you need to purchase to assemble the computer. If, however, you have no questions about the choice of components for the system unit, you know how much and why, or everything has already been bought and is waiting in the wings, then you can proceed to the second part of the article - directly to. But if something is not completely clear to you and there are some questions, doubts, it is better to read this material again, in order to finally choose what you really need, assemble a computer with your own hands and at the same time not overpay too much.

Consider the composition of the system unit, what are we going to assemble it from? First of all, this is the processor itself, which we will install on the motherboard. The motherboard, in turn, is the foundation of the computer, where, in addition to the processor, RAM, sound and video cards are installed. Below we will look at how to choose both the "motherboard" and other components.

What, in fact, the "thought process" itself takes place in is the computer's RAM.

The disk optical drive is designed to read information from laser discs various formats. Whether to equip a system engineer with it or not is a purely personal matter, it all depends on your goals, tasks, capabilities. As an option, operating system can be installed using a bootable USB flash drive, and drivers, programs and games can be downloaded from the Internet.

The power supply sometimes comes with the case, but when assembling the computer yourself, it is better to take it separately. Its main characteristic is output power.

And, finally, such devices that belong to the computer, but are not part of the system unit: monitor, mouse, keyboard, uninterruptible power supply (you can do without which it is possible, but undesirable).

Processor, motherboard and RAM

Processor speed is essential. The powerful processor ensures high speed of the computer. If you are going to play computer games or use design programs, then you need a processor with a clock speed of at least 2 GHz and at least 2 GB of RAM. Better if these two indicators are higher. Some extreme PC games are very resource-intensive, so you should be prepared to buy a powerful processor from an older AMD or Intel lineup. Pay attention to such a parameter as cache memory, it works roughly on the same principle as RAM, only much faster and directly affects the speed of the processor. It will be great if its volume is 3 MB or more. Processors can be supplied in the BOX configuration, this is when it is already equipped with a cooler, or OEM, in which case you will have to buy a cooling system for the processor separately, however, they are relatively inexpensive and available, so this should not be a problem for you.

Motherboard

The motherboard is the "foundation" of the computer. Today, several manufacturers are leaders in quality and price: Gigabyte, Asus, Msi, Foxconn, AsRock. Plus, if you are assembling a powerful gaming computer, it is advisable to take an ATX motherboard, because it has a larger number of slots and connectors, it is more convenient to install and mount, accordingly, you can attach a lot of different things to it.

Before purchasing a motherboard for your computer, make sure that the selected processor is compatible with it. Pay attention to the socket (the socket for the processor installation), it must be similar to the processor socket, otherwise you will have to put the "stone" on the "mother" with a hammer, which is not good. Also note if it has all the required slots and connectors.

RAM

RAM is now common in two types: DDR2 and DDR3. DDR2 is already living out the time allotted to it, it is being replaced by a faster DDR3, and DDR4 is already on the way. Motherboards can support one or both types. But it is better to put the RAM, of course, of the same type. The principle is simple - the larger the volume, the better. And, as has been said more than once, for the modern home computer it needs at least 2GB.

Video card

A good graphics card will give you great picture quality, and is a must for anyone who will be working with graphics or using a DIY computer for PC gaming. Nvidia and AMD are the most prominent brands. The rest of the manufacturers - insofar as. However, it will be extremely difficult for you to "run into" an unscrupulous manufacturer. The fact is that very few people can afford to develop video chips. The vast majority of video card manufacturers use technology and manufacture their products licensed from giant manufacturers.

The meaning of the choice here is the same as with RAM - the more the video card's own RAM and its frequency, the more sophisticated toys it will pull. For games, RAM should be at least 1GB, for an office, 512MB is enough (or it is quite possible to get by with a video core built into the processor). No less important is the frequency of the video processor itself (from 600 MHz and higher) and throughput data buses (at least 128 bit).

Hard disk, or hard drive, also known as HDD

In order not to puzzle over what is more important for us, performance, volume or something else, it is best to put at least two hard drives on your computer. One hard drive - with a high rotation speed of 7200-10000 rpm for the operating system (now they are replacing solid-state SSD-drives), and the second hard drive with a speed of at least 5400-7200 rpm for storing files. It is recommended to opt for the 7200 rpm models. They optimally combine access speed and moderate heating.

First of all, the purpose of a hard disk is long-term data storage. Accordingly, you need to choose its capacity depending on how much of this data you are going to store on it. If you are a movie fan and you have a large collection of films, especially if the films are in HD format, then the larger the capacity of the hard drive, the better. Currently, the prices for hard drives have dropped significantly. You can get a 1TB hard drive quite cheaply. Moreover, the cost of storing 1GB of information is significantly reduced with an increase in the total volume of the selected hard disk. When choosing a hard drive, pay attention to such characteristics as the amount of buffer memory. Currently, the models with 16, 32 and 64 MB buffers are mainly presented. It is preferable to opt for the latter. Also make sure that you buy a SATA3 hard drive from a good manufacturer and with a warranty provided, this will allow you to repair or replace it free of charge in case of malfunction.

Frame

The choice of case will depend on your aesthetic preferences. Some of the cases are delivered with a pre-installed power supply. If you choose such a case, make sure that the output power of the power supply is sufficient to connect all the necessary system components.

How to choose a case for your computer >>> read here.

Power Supply

The best solution would be to purchase a power supply immediately with an uninterruptible power supply (UPS). In any case, you take a case with a built-in power supply or purchase them separately.

But, in any case, the main characteristic of the power supply is the total output power going over several buses with different voltages. The main bus is the one that supplies 12V. In addition to it, there are buses with a voltage of 3V and 5V, but the main attention should be paid to the main bus. And the total power of the power supply unit for all outputs should be more than the total power consumption of all components of the system unit by 40-50 percent, which will make it possible for future independent upgrades of the computer without replacing the power supply unit with a more powerful one. Well, pay attention to the number of connectors and the length of the cables (at least 45-50 cm), especially when the power supply is located at the bottom.

Optical DVD drive

When purchasing a DVD drive, pay attention to the read and write speed, the higher the score, the better. It is desirable that the drives belong to a well-known brand such as Sony, Pioneer, Samsung, they provide good performance and long service life. It is highly discouraged to purchase a CD-ROM, non-burnable DVD drive and other obsolete components. However, it is quite difficult to find them on sale now. But the prices of Blu-ray burners are gradually dropping, so they will soon push DVD drives off store shelves.

And, in short, about the choice of additional accessories for self-assembly of a home computer.

Keyboard

There are a huge number of models for every taste. If you plan to type a lot, take a look at the pyramid models, your hands won't get tired as quickly as with keyboards with a regular layout.
If you are a gamer or music lover, then choose keyboards with special buttons that add additional functionality. This provides additional convenience for music lovers and gamers, while increasing the price of such a device.

Mouse

When choosing a mouse, you need to be guided by approximately the same characteristics as when choosing a keyboard. The main thing is convenience. For some users, it will also be important to appearance devices. Some mice have additional buttons that allow, for example, control the browser, the speed of the cursor on the screen. The mouse should optimally fit the size and shape of your palm. It is these parameters that should become defining for you when choosing and buying this device.

Monitor

The cost of the monitor will depend on its diagonal size and resolution. Accordingly, the more these two indicators are, the higher the price. It is desirable that the diagonal is at least 17 inches. However, if you are purchasing a computer for work, then you should not chase too large a diagonal. Large screens are more suitable for a multimedia computer. Resolution determines the clarity of the picture. Decide how important it is to you and based on this, choose a monitor model. Finally, when purchasing a monitor, pay attention to which port (s) is used to connect to the motherboard. The nests must match. Although there are various adapters on the market, it is still better to initially select components that fit each other.
