A gaming PC can cost you thousands of dollars. Wow… pretty hurt, isn’t it? But if you know how to choose accessories and combine them together, your money will be less than $1000! So, what is the way to choose best prebuilt Gaming PCs? This article of JustGage will guide you the best prebuilt Gaming PCs under $800.

Buying Guides

Of course at the price under $800, you cannot build yourself a "dream" gaming system that the suggestions given here are only relative but also quite detailed, and considered in many angles that is acceptable. And if you follow this guide completely, those games like Sekiro, Dark Souls 3 or even Crysis Remastered Edition will be processed with their best quality!

1. CPU Processors Intel Core i5-9400F

The CPU with the suffix "F" of the Intel green team has been released and is very popular. Because it gets rid of the integrated graphics processor (iGPU). This has great benefits because it helps to reduce the CPU price quite a lot. While the other specifications remain the same compared to the CPU version of the same type but without the suffix "F". CPU Processors Intel Core i5-9400 is one of those products. Its specs and i5 9400 are the same, except without iGPU. With 6 cores 6 threads, clocked at 2.9 - 4.1 GHz.

On the other hand, when building a gaming computer, you'll most likely use the discrete graphics card to maximize power. So choosing the i5 9400F CPU is the best match here.

But if your budget is below that, you can consider to AMD Ryzen 5 2600, with not exactly the same quality but at a lower cost, and might be suitable for our build.

2. CPU Air Cooler Deepcool Gammaxx 400

With this configuration you can only use the stock heatsink included with the CPU. But for optimal durability, more stability when gaming, installing a third-party air cooler is suitable. Deepcool Gammaxx 400 will help you to cool down this CPU.


With Nvidia’s Turing-based GPU line-up laid bare in front of us, it’s so much easier to draw comparisons and make recommendations without hemming or hawing about cards-to-come. We already know that VGA GIGABYTE GeForce RTX 2060 is a good performer at 2560 x 1440 and can hold its own at 1920 x 1080 with real-time ray tracing enabled in games like Battlefield V.

We also know that the GeForce GTX 1660 Ti is a better value in terms of performance per dollar. But if you’re looking to arm yourself with the Turing architecture’s signature features for the lowest price possible, GeForce RTX 2060 is where it all begins. Is it worth paying extra for a premium 2060, though, or should you stick with a baseline model at $350/£330?

4. RAM CORSAIR Vengeance LPX DDR4 2666MHz 

This “little bastard” kit aims to conquer all competitors by doubling the number of ranks per DIMM. Why do I say that? Intel’s H370 and B360 chipsets instruct its Core i5 (and above) processors to lock out any memory settings above DDR4-2666, which is particularly unfortunate in a market that’s moved way past that setting. 

DDR4-3200 is now mainstream within the enthusiast PC market, and is often treated as such by the memory sellers that cater to enthusiasts and gamers. Thus, the best way to get a top-performing brand new DDR4-2666 kit would be to dial the way-back machine to 2016 and get the high-performing kit from that time. Barring that, Corsair has a workaround.

The difficulty getting there is that today’s integrated circuits are manufactured in 8Gb and 16Gb capacities, and it takes eight of these ICs to make a 64-bit rank. Looking at the mismatched lot numbers, it appears that Corsair dug through its old inventory and found enough mediocre 4Gb ICs to produce an entire run of 8GB dual-rank DDR4-2666 DIMMs for this kit.

RAM CORSAIR Vengeance LPX supports BUS up to 2666MHz, compatible with CPU i5 9400F and below motherboard.

5. Mainboard MSI ProSeries Intel B365 LGA

The B365 chipset is seen as an upgrade of the B360 suitable for Intel's mid-range 9th generation CPUs. The name says for itself a lot, B365M PRO-VDH motherboard has told us it has standard Micro-ATX size, supports 1 VGA port, 1 DVI port, 1 HDMI port, running B365 chipset.

It supports up to 64GB RAM BUS 2666MHz across 4 slots. So choosing 2 8GB bars is very suitable. If you want to upgrade the RAM in the future, you can install two more half 8GB sticks that also run dual channel. In terms of storage capacity, the MSI B365M PRO-VDH also supports an NVMe M.2 SSD slot using a PCIe x4 lane. There will still be 6 ports for the SATA 3 hard drive.

The PCIe slot has been reinforced by MSI with a reinforced steel case to make the port more secure when you install a too heavy graphics card.

6. Internal SSD Crucial BX500 240GB

Say the best prebuilt Gaming PCs under $800 without an SSD? Definitely not the best! Crucial's BX500 is the successor to its popular BX300 line of SSDs. Like the company's mainstream MX500 brand, the BX500 skips over the 400-naming scheme. But, unlike the MX500, the BX500 doesn't offer much of an upgrade path over its predecessor.

The BX series is a streamlined, no-frills SSD with fewer accessories and features than the MX series. Crucial launched the BX series to tempt buyers into purchasing flash when other options in the market were too expensive.

7. Power supply EVGA Supernova G1+ 750 Watt 

With the best gaming PCs under $800, you see this configuration for the present and convenience to upgrade in the future you should use 750Watt power supply. EVGA is without a doubt one of the best-known brands in terms of PC parts and components. With most knowing them for the Nvidia range of graphics cards, they are also one of the most popular suppliers of high-performance power supplies.

EVGA Supernova, with this being both certified as gold rated and coming with 750w of power, from that alone most users should know that they are getting something not only packing a solid amount of output but also being able to do it with high efficiency.  With the main 12v output coming through a single rail, there is also no need for any of that tricky business of balancing that can have a significant impact on performance.

But if you want choose another one with lower cost and still have the same quality (not exactly but can be the best optional in this case), we recommend you to look for Corsair RM 750 has high efficiency operation for lower power consumption, less noise and cooler temperatures

8. Computer Case ionz KZ14 M/ATX 

The trend of current Gaming PC systems is to use transparent cases. Just modern and showcases the components inside. And ionz KZ14 M/ATX  has a glass side window to show off your build. Modern and stylish clear acrylic panel design. As comfortable in a modern office as it is in a Gaming room. Well, ideal for those on a lower budget, right?

2. And the weak of this build?

Well, I have to say with this build you must accept that the PC storage has a bit limited. But overall, it’s OK.

3. Which games I can play after paying $796,53?

The ability to play games in High, Ultra settings in most of all games today with the RTX 2060 card is obvious. It can even be good with a 144Hz refresh rate screen. In addition, you can also play many games at 2K resolution above 60 FPS.

4. Is there another way to build a gaming PC under $800 but still has the same quality as this?

Yes, of course. There are many ways like this beast Fierce High FPS Gaming PC: Intel Core i5 9400F Six-Core CPU costs $639.90, but in this article we choose the best and recommend it to you.

In case you can pay a bit more $90, we bring this to you: PALICOMP Gaming PC INTEL i7 9700F 3Ghz Turbo 4.7Ghz Eight Core, it has 16GB Ram and SSD 1TB, wow!

5. Let’s say I only have $700 right now, what I should do?

Hmm, in that case, you can consider not to buy the Computer Case ionz KZ14 M/ATX and choose the other which has lower cost, like ionz KZ 11 just $18,95. With this decision, you still carry on our best prebuilt gaming PCs under $800.

Final Thoughts

The ability to upgrade at will are the advantages of building your own PC. You are free to choose a stronger component if it is convenient for you. Although this configuration can let you experience many games over a long period of time. In that case, we would recommend some upgrade for you:

Upgrading more storage space 240GB is enough for the installation of the operating system, basic software and some good quality games. However, with a fairly powerful configuration like this, you will enjoy playing more heavy games. This capacity can fill up quickly. If it is, I will upgrade to a 1TB storage for more offline games, like Crucial BX500 1TB. The motherboard supports quite a lot of SATA ports and M.2 SSD slots so it's comfortable, maybe ASUS LGA1151 is the best in this case.

The Core i5 and RTX 2060 are great. However,  you can still upgrade your PC to higher and even the best. For example, Core i7 9700F and RX 5700 or RTX 2070, they’re so awesome. Of course all of them cost more money, but the more for the best product, right? And still, the available power supply in this article can handle all of them.

In short, depending on your purpose and needs to choose the best prebuilt gaming pcs under $800. Below, our experts recommend some suitable items for you:
