How to build a gaming computer?

Как собрать игровой компьютер

Anyone who has an understanding of how the computer case works and knows the function of each part can assemble a gaming computer. Self-assembly results in a PC that fully meets the user’s requirements.

At first glance, building a gaming computer on your own may seem very difficult. In reality, even beginners can do it, provided they strictly follow the instructions.

How to assemble a gaming computer: tools and components

If you have decided to assemble a gaming computer, you must first determine your budget. The cost is a key factor in choosing components. However, it should be noted that additional expenses await you besides the main components of the computer case.

To assemble a computer yourself, you will need a well-equipped workplace. Firstly, you will need a large, flat, well-lit surface. A computer desk would be the perfect solution. Some people prefer to assemble a PC on the floor. If you decide to do the same, be sure to remove the carpet or other textile floor coverings. Static electricity can damage sensitive components of the future computer.

In addition, you will definitely need a set of tools for servicing the PC. Such a kit can be purchased at any electronics store.

The next step is to choose the components. A standard computer system consists of 8 components, which include:

  • Central Processing Unit (CPU). This element is responsible for the computer’s processing power. The CPU’s specifications directly affect the computer’s speed and performance. It is also one of the most expensive components of a computer.

  • The motherboard. This component combines the above-mentioned components into a single system. The quality of their interaction directly determines the power of the gaming computer.

Как собрать игровой компьютер

  • Cooling system. When working with demanding programs and games, the main components of the computer heat up. This can lead to reduced performance and the risk of damage. To prevent this, a cooling system is built into the computer case. Depending on the design, there are air and liquid cooling systems.

  • Case. To protect all the components of the system unit described above, they are placed in a box. It will reliably protect the PC elements from damage and other negative factors.

Как собрать игровой компьютер

The cost of a assembled gaming computer depends on the chosen components. The selection of hardware components for a PC should be approached with maximum knowledge and responsibility. The main difficulty lies in the fact that components are not characterized by universal compatibility. To build a good gaming computer, each part must perform its functions 100%. This can only be achieved if all system components are fully compatible.

How to build a powerful gaming PC: step-by-step guide

Choosing the right hardware for your computer is only the first step in the process. The next step is actually assembling the PC. For those who have some knowledge of computer hardware, this stage will not be too difficult. However, if you are unsure of your abilities, it is better to use ready-made PC builds or entrust the preparation of the computer to specialists.

If you have a workspace, good lighting, and minimal skills with hand tools, you can assemble a gaming computer yourself. The main stages of this process are described in detail below. Keep in mind that the method of installing components may vary slightly. However, the general order of assembly is the same.

Step 1: Installing the CPU

Firstly, you need to unpack the motherboard. All the computer components are installed on it one by one.

Как собрать игровой компьютер

In this example, the ASRock Fatal1ty B450 motherboard is being used. The package comes with a foam pad, which is recommended to be placed under the motherboard if you’re working on a table, floor, or any other hard surface.

After unpacking, the central processor needs to be installed on the motherboard. In this build, the AMD Ryzen 5 3600 AM4 six-core processor with a standard clock speed of 3.6 GHz is being used.

The socket for the processor is located in the central part of the motherboard and has a square shape. To open the locking mechanism, it is necessary to lift the side lever of the socket upwards.

Как собрать игровой компьютер

The processor should be inserted into the socket. Make sure that the contacts of the processor match the socket. Then lower the lever to secure the CPU on the motherboard. The entire procedure should be done carefully to avoid damaging anything.

To continue the PC assembly, we move on to the second step: installing RAM.

Connecting RAM is generally not more difficult than installing the CPU. You can use one, two, or several RAM sticks. The maximum amount depends only on the characteristics of the motherboard and the CPU. In this build, we are using two 8GB GoodRAM IRDM Pro RAM sticks.

Как собрать игровой компьютер

Special slots equipped with locking mechanism are provided on the motherboard to install RAM sticks. The locking clip is located on the side of each slot (there are 4 of them on our board). Depending on the motherboard model, the clip may be located on one or both sides of the slot. Before installing the RAM stick, the clip must be opened.

Как собрать игровой компьютер

To install RAM, insert each stick into a separate slot. When the RAM is properly seated in the slot, the locking mechanism will close automatically.

Stage 3: Installing an SSD

We’ve been discussing the components necessary for building a PC, and one of the key elements we’ve noted is the hard drive. Currently, there are two main types of storage devices used for computers: solid-state drives (SSD) and hard disk drives (HDD). The former is preferable because SSDs operate faster, wear out more slowly, and are easy to install. We’ll take a look at the installation process using the example of the Silicon Power 240 GB M2 SSD.

Как собрать игровой компьютер

To install an M2 interface SSD on a motherboard, a separate connector is provided. It is present on almost all modern motherboards released after 2016.

Как собрать игровой компьютер

Next, you need to find this connector on the motherboard and install the memory block. Insert the SSD into the slots until it clicks into place. It should sit slightly raised.

Как собрать игровой компьютер

You need to carefully press it against the motherboard and secure it using a special M2 screw. Usually, it comes in the package with the motherboard, not with the SSD itself.

Stage 4: CPU Cooling

As noted above, under heavy loads, the CPU starts to heat up. To improve heat dissipation and ensure quality cooling, thermal paste must first be applied to the processor.

Как собрать игровой компьютер

After that, you can proceed to installing the cooler. In our build, we’re using the Deepcool Gammax 400 EX tower cooler.

The installation process is as follows:

  1. Remove the covers around the processor if they are present in the design of the motherboard. To do this, you need to unscrew them with a screwdriver.

Как собрать игровой компьютер

  1. After that, assemble the backplate. It is attached to the back of the motherboard and serves to securely mount the cooler and protect against damage. The screw studs come out to the front of the board. Rubber pads are put on them, and then hexagonal spacers are screwed on top.

Как собрать игровой компьютер

  1. It is recommended to apply thermal paste before installing the cooler onto the CPU to improve heat dissipation and ensure quality cooling. If thermal paste has not been applied previously, it can be applied directly before installing the cooler. The simplest way is to pour the cooling compound onto the central part of the processor cover and then press the cooler plate onto it. The paste will spread on its own. The main thing is to ensure that there is not too much paste and that it does not spread onto the motherboard.

Как собрать игровой компьютер

  1. We remove the protective film from the cooler’s base. We put the device on the hexagonal standoffs previously attached. The base should fit snugly against the processor cover. We secure the cooler’s reinforcement plastic to the stands using spring screws.

Как собрать игровой компьютер

  1. We put a fan on the radiator assembly attached to the motherboard. For this, spring lock mechanisms are used on the sides.

Как собрать игровой компьютер

The cooler is fixed, but it won’t work until it’s connected to the motherboard. To do this, the contact cable of the cooler must be placed into the CPU_FAN 1 connector.

Stage 5: Case and Power Supply

Unpack the PC case. In our example, we are using the DeepCool Matrexx 70 ADD-RGB-3F case. If necessary, additional fans can be installed in the case. All cables responsible for connecting the lighting, fans, and computer ports must be routed out through the back of the case. This will allow for proper organization of the internal space and better airflow.

The next step is to install the power supply. It should be installed with the fan facing downwards. Attach the power supply to the case using screws with a wide head. You will need 4-6 screws, depending on the design of the case and the power supply itself.

Как собрать игровой компьютер

Next, you can proceed to install the assembled motherboard. The supporting wall of the case has holes for mounting and windows for wire entry.

Next, you can proceed to install the assembled motherboard. The supporting wall of the case has holes for mounting and windows for cable entry.

The motherboard comes with a special backplate that is used to further expose the ports and connectors. The backplate is inserted into the case, and then it needs to be slightly pressed from the inside to fix it.

Как собрать игровой компьютер

Then you need to place the motherboard in the case and determine the most suitable position for the mounting screws. The position of the screw holes may vary depending on the manufacturer of the case. Therefore, it is worth determining a convenient position for the motherboard in advance. Fix the mounting screws in the appropriate places. This can be done by screwing them in using pliers or by hand.

Как собрать игровой компьютер

Lower the motherboard into the case while holding onto the cooler tower. It should be placed on the pre-installed mounting standoffs. Make sure that all the connectors and ports align with the openings on the I/O shield that was installed earlier.

Как собрать игровой компьютер

All that’s left is to secure the motherboard inside the case. To do this, screw it in using screws with a wide head all around the perimeter.

Как собрать игровой компьютер

The 6th step: Connecting cables.

The first step is to connect the fans located inside the case. This refers not to the cooler, but to the fans inside the case itself. Since there are several of them, it is recommended to use a power splitter that comes with the case.

Как собрать игровой компьютер

The case fans’ cables should be connected to it. The connector of the fan splitter should be inserted into the FAN socket on the motherboard.

The other ports and connectors are also connected to the motherboard in a similar way. This method is also used when connecting the buttons located on the front panel of the case, which are responsible for power on/off and reboot.

The connection of the CPU power supply is slightly different. For this purpose, a cable marked CPU is included in the kit.

Как собрать игровой компьютер

To connect the CPU power, the cable labeled “CPU” is provided in the kit. It’s easiest to route it to the motherboard through a window in the corner. The corresponding connector for this cable is located in the same area.

Как собрать игровой компьютер

After that, it is necessary to provide the motherboard with electricity. To do this, a cable with a wide 24-pin connector is used.

Как собрать игровой компьютер

The connector for the 24-pin connection is usually located on the right-hand side of the motherboard. It is wide enough, so finding it after installing it in the case should not be difficult. Typically, the connector has a locking mechanism to ensure a secure fit. You need to insert the plug into the slot on the motherboard and push it in until the locking mechanism snaps into place automatically.

Step 7: Connecting the Graphics Card

Installing the GPU is the final step in building a PC. This is because if you want to build a powerful gaming computer, you will likely be using a graphics processor with its own cooling system. If you install it at the same time as the motherboard, it will be inconvenient to connect the cables to the ports and power the hardware components.

The PCI Express connector is responsible for connecting the GPU to the motherboard. It is wide enough, so finding it should be easy. Before installation, you need to push the lever to open the locking mechanism.

Как собрать игровой компьютер

Insert the card into the PCI Express slot. The locking mechanism will automatically close and fix the card in place.

Как собрать игровой компьютер

Finally, secure the card using screws. It is better to use a screwdriver for this. The graphics card is a relatively heavy component, so it must be securely fastened to the frame of the case.

Как собрать игровой компьютер

The graphics card is powered through a PCIe cable that comes with the package.

Как собрать игровой компьютер

After connecting the PC, you can close the case. The system unit is ready to use. All peripheral devices need to be connected: monitor, keyboard, and speaker system. After the first launch, BIOS setup, driver installation, and operating system installation will be required.

How to assemble a gaming computer online?

If you are having trouble selecting components, you can use a web-based configurator. This is a special service for assembling a PC online.

Such a tool is quite convenient for several reasons:

  • You don’t need to monitor prices yourself;
  • In the configurator, you can select components without compatibility errors;
  • You can assemble a PC that strictly meets your requirements.

Online configurators are available in major electronics stores. Also, assembly simulators are used as calculators. With their help, you can accurately determine the cost of a ready-made computer, taking into account auxiliary materials and component installation.

Is it more profitable to build a gaming computer yourself than to buy it in a store?

One of the main questions that interests almost everyone who has decided to build a gaming computer on their own is how profitable it is. Is it really cheaper to do it yourself or is it better to buy a ready-to-use system unit.

Как собрать игровой компьютер

It can be confidently stated that self-built gaming computers are cheaper than ready-made ones from stores. This is easy to verify by comparing the cost of a self-built computer and the sum of its components purchased separately. On average, the cost of such a PC will be 15-20% lower. If you can buy components on sale, you can save even more.

Other advantages of DIY assembly include:

  • minimization of risks associated with defects and factory defects;
  • the ability to assemble any type of computer system;
  • the ability to use parts from an old PC;
  • the ability to make changes to the configuration at any convenient time.

However, there are also disadvantages. Self-assembly requires a lot of time to order components. If the components are not selected correctly, the entire responsibility lies solely on the assembler. No one will compensate for the cost of a damaged part.

Some people build gaming PCs for resale or on-demand. This type of earning is ideal for those who love computers and can spend days installing hardware components and further system setup. Ready-made assemblies can be sold through online stores, bulletin boards, or social media pages.


Building a gaming computer is not as difficult as it may seem at first glance. It does not require special education or experience. Only a minimum amount of knowledge about PC devices and the ability to use a screwdriver are needed.

You have learned what is needed to build a gaming computer yourself. The main task for the assembler is to select the optimal set of components. To end up with a high-performance system, they must be maximally compatible. The cost depends on the characteristics of the selected components. A computer can be assembled even with a minimal budget. However, if you want a high-performance PC, it is better to purchase more expensive parts. It is possible to invest in a computer for 40-50 thousand rubles.
