How to Build a Gaming PC: Easy Guides for Beginners

by Daniel J.

Want an uncompromising gaming PC? You have two options, and both are easier than you think: one is safe, and the other is interesting. Some say, “it’s better to pay someone who will make you a computer.” Expensive? But do not bother with accessories. There is another opinion “if you want it to work, do it yourself.” So, how to build a gaming PC by yourself?

Many of the ready-made expensive desktop computers could be cheaper. Assembling the system yourself, you definitely do not spend money on components that you do not need. Are you sure that every penny spent goes on what is really important to you?

However, having understood the general essence of this guide, you will be able to build what you need by focusing on those tasks for which you are building your gaming computer.

What do you need to build a PC?

To build a PC, we will need the following components (note that prices are approximate).



Recently, AMD has taken the lead from Intel, and as games increasingly use multi-core architectures, this leadership remains. If you have some money and overclocking plans, then the AMD Ryzen 5 3600 will be a great choice. But since not every user is ready to engage in overclocking, you can look towards the Zen2 generation.

Moreover, the new product is 20% more productive than its predecessor. The difference in price, of course, is quite tangible, but it is always the case with newcomers to the market. You can choose any processor that suits your budget more. Not everyone is ready to exchange 40% of the initial cost of a weaker processor for 20% of performance. See these processors:

If you stayed at the Ryzen 5 3600, then the overclocking capabilities of the motherboard should not interest you. All representatives of Zen 2 are perfectly dispersed from the factory, and home user overclocking is impractical due to the fact that the performance gain is small and the heat and power consumption are huge.

Therefore, focus on the cooling system of the power circuits, the number of various slots and video outputs. Also, do not overpay for 4 slots for RAM. It is almost impossible to overclock 4 RAM slots paired with any red processor of the latest generation. And if you succeed, then the increase in frequency will be very small. Therefore, our choice is 2 slots for memory modules. Here are some motherboards with different purposes:

Video Card/Graphics Card:

Graphics card is another most important component for gaming PC, and it’s costly. But modern technology offers the buyer a huge number of options, almost under $200. This is especially noticeable in the budget and middle price segments. While we are still waiting for a wide variety of non-reference modifications of the AMD Radeon RX 5700 and AMD Radeon 5700 XT, we have to choose between green graphics adapters.

To feel comfortable in all AAA projects in the next couple of years, you will need to fork out a minimum of RTX 2060. Sometimes, you can try out a new ray tracing technology in undemanding games, which will appear more and more.

Nvidia’s graphics chips are traditionally very cold and have a modest appetite. You can take absolutely any modification, even the version with one fan will do. However, if the budget does not allow, then 1660 and 1660 Ti will also be an excellent choice.

Storage/Hard Drive:

SSD won the competition of HDD against SSD. We can no longer imagine loading from a spinning disk, no matter what the wallet tells us. Of course, there is a small problem: games are taking up more and more space. For example, Tom Clancy’s The Division 2 “weighs” already 55 GB.

Given this circumstance, especially when calculating the size of the OS itself and a few more games, the available 128 GB SSDs do not look as attractive as before. A modern PC needs at least 256 GB, and even that will soon be missed. This explains our choice.



If there is something to which modern games are more demanding than their predecessors, then this is memory. And the point here is not only in speed but also in capacity. Today, 8 GB is the most necessary minimum, and 16 GB is recommended.

In addition to volume, you should pay attention to overclocking potential. If you do not want to mess with overclocking, you can immediately take a closer look at the high-frequency memory slats. For example, the Kingston HyperX FURY DDR4 RGB 3433 Mhz. The most practical option for all times and nations is the already proven HyperX Fury 16GB 3200MHz DDR4 CL16 DIMM memory slats.

To good overclocking potential, this RAM has high stability, and that’s all we need. The price is not the lowest, but not much higher than the most budgetary decisions. For stability and aesthetics, have to pay a little extra.

Power Supply:

Power Supply

In the latest processors and chipsets for motherboards, AMD really uses power sparingly. This means that we do not need a super-powerful power supply. The SSD also consume less power than hard drives, so the video card remains the only major “eater” of electricity.

The RTX 2060 is not very demanding, so even at full load, the whole system will consume something around 400 watts. Additional power will provide opportunities for upgrading if you later want it. So, you can use a medium budget power supply in your computer.

PC Casing:


The design of the Corsair Carbide 200R allows you to install accessories without special tools, and there is enough space for the RX 2060 since the drive bays are conveniently located to accommodate even a long card. The grooves allow you to lay the cables conveniently, and there is plenty of room for additional cooling – in case you need it.

How to Build a Gaming PC: Putting it all together

So, the components are bought, it’s time to put it all together. Before starting, we note that we made some assumptions about what we have. We take for granted, for example, that you have a monitor to which you connect your new computer. We also hope that you already have a screwdriver kit, keyboard, and mouse. So, let’s start the assembly.

Testing before Build the PC:

  • Remove the motherboard from the antistatic bag in which it is packaged, and install the processor in the socket. Carefully insert the memory slots and graphics card into their slots.
  • Before installing a processor cooler on the board, be sure to apply a little thermal paste. This will provide good contact between the top of the chip body and the cooling plate, filling small scratches on the surface with a heat-conducting layer. Just one drop the size of about a couple of match heads. You can not spread the paste – just install the cooler on top, and it will be distributed in a good even layer.
  • After making sure that everything is connected, you can connect the power. Before that, make sure that the main ATX cable is connected, as well as the 8-pin CPU power cable. You also need to connect the 6-pin and 6 + 2-pin PCIe slots to the video card.
  • You can’t think about drives yet. Connect the monitor to the graphics card and keyboard to the chassis. Turn on the power supply and start the machine – use a screwdriver to fix the power connector on the back of the case and press the power button.
  • Now you need to make sure that the computer starts, the fans rotate, the displayed is working, and you can enter the BIOS. When the motherboard logo appears on the screen, press the [Delete] key on the keyboard, after which the BIOS setup interface should start. Ensure that the motherboard shows the presence of the CPU and correctly determines the amount of RAM.
  • Hooray, it works as it should! Now turn off the machine and disconnect the power supply. Disconnect the power cables from the motherboard and remove the video card. Memory, processor, and cooler can be left in place.

1. Installing the power supply

Before placing the heart of our PC in a new case, we first install the power supply. It is better to do this right away than after the other components have taken their place. Orient the power supply so that the inlet fan draws in air from the outside.

2. Installing the motherboard

Now it’s time to put everything in its place. Attach the motherboard backing to the chassis. Pull out all the cables – you don’t want to accidentally catch on any wires – screw the substrate supports to the case and put the board in place.

3. Connects Hard Disk

The next component we install in the chassis will be a solid-state drive. Here we have a wide selection – there are many places where you can install it. We suggest choosing a rack on the front of the chassis. Have you attached a SATA cable? Everything, you can move on.

4. Adds Video card

Now it’s the turn of the video card. Make sure that you do not mistakenly hook any wires, install the graphics card in the main PCIe slot and screw the bracket to the case so that it stands reliably and safely.

5. Connects the Front Panel Connectors

You need to connect the front panel connectors to the motherboard connectors. Consult the manual to determine where the audio and USB connectors are located on the front panel. Where to connect the power wires, you already know – to the toggle switch, disk and power indicators. Attach the cables properly.

6. Wires Inside the Case

Randomly running wires interfere with the free airflow inside the casing. First, connect the long power cable to the motherboard, and then the power connectors of the CPU, GPU, and disk and ensure that the fans are also powered.

7. Everything is almost done.

Everything is almost ready. Now connect the monitor, keyboard, and mouse. Leave the side panel open when you start the machine for the first time to make sure that all fans rotate. Press the power button, and our assembled computer should work.

8. The speed of memory

Go into the BIOS and check that the processor temperature is normal (no higher than 40-50ºC), that the hard drive is visible and selected as the main boot option. Also, check your RAM settings: the memory should run at its rated frequency. If there is any problem, change the setting using the appropriate profiles. Save the BIOS settings and exit.

9. Installing the operating system

In the latest computers, you are unlikely to find an optical drive. Therefore, to install the OS, you need to create a system installation flash media on another PC.

10. Boot from USB – and go!

Install the system flash drive into the USB connector, boot from it via the BIOS, and install the OS. Regardless of which OS you use, in our time, it is done quite easily. When everything is ready, go to the Network and update the video card drivers. Everything – you are ready to play!
