We assemble a gaming computer for 800$

Compilations of the best processors, the best RAM, motherboards and drives are great. But not all users will be able to combine them into a well-functioning and well-balanced system. Therefore, from time to time we also make full-fledged configurations for a certain budget, which make it as easy as possible for self-assembly of a computer.
This time we invite you to familiarize yourself with our assembly of a very good gaming computer for 800$. It involves the purchase of components in two stages: it lacks a discrete graphics card, and so far it relies only on the processor’s integrated GPU. But, if in the future you add an RTX 3060-level video card to it, and preferably an RTX 3070, it will pull almost all the games that have been released to date.

Choosing a processor
- Intel Core i5-12600K — 220$
Computers
The best processors in 2022: our top for all occasions
The price of our assembly is limited to 800$, so with all our desire we will not be able to install the fastest Intel Core i9-12900K gaming processor into it, and limiting the assembly only to games by choosing a highly specialized AMD Ryzen 7 5800X3D can hardly be called the best option either. Therefore, our choice fell on perhaps the best mid-range processor today — the Intel Core i5-12600K.
The Intel Core i5-12600K not only boasts superior performance for its price range. Equally good for gaming and work, this versatile processor supports DDR5 RAM, can handle fast PCIe 4.0 M.2 SSDs, and supports PCIe 5.0 as a good future-proof.
Choosing a cooling system

Well, since we chose not a boxed version of the processor, we also need an appropriate cooling system. By itself, the Intel Core i5-12600K has a fairly low TDP. But this processor runs great, and this should be taken into account when buying a cooler — you need to choose it with a large margin of power.
The relatively inexpensive ID-COOLING SE-226-XT ARGB is perfect for our tasks. This cooler can efficiently cool processors with TDP up to 250W. And, therefore, when cooling the Intel Core i5-12600K in normal mode, it will not need to go to full speed — the noise from its operation will be almost imperceptible, and the cooler itself will last you much longer. It also has the much-loved RGB lighting.
Choosing a motherboard
- GIGABYTE Z690 UD — 190$
Computers
How to choose a motherboard for a home, office, gaming computer?
GIGABYTE Z690 UD based on the flagship Z690 chipset boasts an excellent power supply subsystem and a very good cooling system for all key elements of the board. It will not only easily cope with the Core i5-12600K, but also allow you to overclock this processor, thereby further increasing its performance.
In addition, the motherboard offers a wide range of USB ports, including high-speed USB 3.2 Gen2x2, three M.2 slots and six SATA connectors. Of the minuses of the board, one can note, perhaps, the cooling on all M.2 slots. Otherwise, this is a great solution at a very reasonable price.
Choosing RAM
- Patriot Viper Venom DDR5-5600 2x8 GB — 100$
We are building a computer on the Alder Lake platform, and it would be foolish not to take advantage of one of its key advantages and not install DDR5 RAM in the PC. Fortunately, its price has recently dropped significantly. For our assembly, we chose not the most expensive Patriot Viper Venom DDR5-5600 memory. Or rather, a set of memory from two bars of 8 GB each.
Of course, DDR5 performs best in modules with a capacity of 16 GB, but 8 GB sticks also provide a noticeable performance boost compared to DDR4, reaching up to 20% in some applications. Therefore, it is actually pointless to assemble a modern computer based on DDR4. Well, the Patriot Viper Venom DDR5-5600, in addition, uses Samsung chips and runs very well.
Choosing drives
- Kingston 512 GB M.2 SKC3000S / 512G — 76$
- Western Digital WD Blue 1 TB WD10EZEX — 41$
Any modern computer involves the use of a solid state drive for the operating system and a hard drive for storing information that is not demanding on access speed — videos, photos, games, software distributions, etc.
As a system drive, we decided to use the Kingston KC3000, which has already been in our tests and has proven itself well. One of the fastest SSDs on the market delivers up to 7,000MB/s sequential read speeds and up to 3,900MB/s write speeds, with 4K block random access performance of up to 450,000/900,000 read/write IOPS, respectively. However, if your budget allows, you can easily take the even faster Kingston KC3000 in the 1TB version.
Using an expensive SSD to store information that does not require high access speed is unwise. And it is much more efficient to buy a regular hard drive for these purposes. And here we did not reinvent the wheel, simply preferring the unchanged classics in the face of the Western Digital WD Blue 1TB WD10EZEX. This HDD has long established itself as a reliable and fairly fast solution.
Choosing a power supply
- Chieftec PPS-850FC 850W — 88$
Purchase
We eat right: how to choose a power supply for a computer
Remember, we said that in order to realize the full potential of our assembly, we definitely need a sufficiently powerful discrete graphics card? With this in mind, buying a budget and weak power supply is a thankless task. And we decided not to save on such an important component of the system, choosing the Chieftec PPS-850FC 850W model.
This power supply uses a quality component base and boasts excellent voltage regulation and a fully modular cable system. Its efficiency is more than 80 PLUS Gold, and its 850W of power is more than enough to power both our system and a powerful graphics card. The only disadvantage of the PSU is a fairly high noise level under heavy load.
Choosing a case
- Zalman S2 — 30$
Tips
How to choose a computer case: basic criteria
An excellent and at the same time inexpensive Zalman S2 case provides very good cooling due to the lower location of the power supply, a mesh front panel and seats for five fans. And the case comes with one fan on the rear panel.
A clear acrylic polymer side panel gives you a view of the system’s internals, while magnetic air filters keep dust out. However, the filters themselves are not very effective, and one way or another you will have to clean the case from time to time.
Results
As a result, we got a very good assembly of a modern computer. Adding an Nvidia RTX 3060/3070-level graphics card to it, you will get a PC that will run all modern games without any problems. Fortunately, in recent months, the cost of graphics adapters has fallen dramatically, and their purchase is no longer such a problem as it used to be.
