Best gaming PC under $400

We’ve updated our best gaming PC build under $400 with one of AMD Ryzen APUs, a capable processor with integrated graphics, which negates the need for a dedicated GPU. While newer 8000 series Ryzen APUs have been released, none of them fit into our very tight budget. The older SKUs still offer semi-decent performance and make sense in a build for less than $400. You don’t need the latest platform to get lower-end performance. We’ve also updated our prebuilt computer recommendations for those who prefer to purchase rather than build, although we strongly advise you to build.

With the 400-dollar gaming PC, our main focus was to extract as much performance as possible from every penny. While we aren’t at the price range where value is at its absolute best, we have enough wiggle room in the budget to make 1080p gaming very playable. While this may not be our cheapest gaming PC build, it’s still extremely affordable with a slightly stronger processor and graphical power. We consider this build entry-level for both performance standards and build difficulty, making it the perfect gateway into PC building. However, you should limit your expectations. This does not come with a dedicated GPU but is set up so you can continue to save for one and then install it without issue.

$400 gaming PC build of the month

The $400 PC build we have set up today offers the best price-to-performance ratio we can achieve with just $400. This PC is equipped with a Ryzen 5 5600G, which will serve the purpose of both the CPU and GPU in this gaming machine. Because of this, the performance is limited to 1080p but can be further improved with the likes of AMD’s FSR. To make sure the 5600G has everything it needs, we paired it with an A520M motherboard and 16GB of DDR4 @3200MHz. Giving the 5600G the best chance of processing high frame rates. We’ve managed to do what many cannot when building a budget PC, we’ve included an NVMe WD Blue SN580 in the components list, ensuring long load times and laggy operating systems won’t be an issue in this build. That’s more than you can say for some more expensive PCs out there.

How we test

We carefully build each of our recommended PCs to ensure the best performance and compatibility. Our PCs are thoroughly tested with everyday use and various games to ensure they can handle demanding tasks, all the while recording temperatures to ensure overall system health and stability. We also test for overclocking capability, but please be aware that overclocking has risks and may void warranties.

Prebuilt gaming PC under $400

It is always a great idea to build your own desktop computer, especially if you’re restricted on how much you can spend. Nonetheless, not everyone is fond of building their gaming computer due to the hassle that comes with it. If you’re someone who isn’t overly keen on the idea of building their own, then you’ll be happy to know we’ve searched the web for the best-prebuilt gaming PC for around $400.

Our $400 Custom Gaming PC Build

Our best custom-built gaming PC for under $400 is an excellent example of entry-level gaming performance when sticking to this price. This PC is designed to give you an entry point into gaming, with the idea of leaving room for future upgrades and the addition of a dedicated graphics card down the line.

While keeping the price relatively low, we can still squeeze in the 5600G, 6 core/ 12 thread APU with Radeon Vega graphics, and a base clock speed of 3.9GHz, with a max boost of 4.4GHz. The 5600G provides enough power to play low-intensive games such as CS2, Fortnite, DOTA 2, and Rocket League at 1080p while maintaining smooth, playable FPS. It may not be the best CPU in the world, but it’s certainly capable.

The motherboard is an area where we can save some money for this budget, that’s why we’ve opted for the ASRock A520M. This board offers enough in terms of features and offers out-of-the-box compatibility with Ryzen CPUs. That being said, it’s still effectively an entry-level board but slots nicely into this $400 build. Ultimately, if you’re looking for an affordable board that’s going to achieve everything you’d want from a gaming motherboard, then look no further.

The Ryzen 5 5600G comes with a stock cooler that we will be taking advantage of in this build to save some money.

Corsair is a trusted and reliable brand that brings some of the most affordable hardware offerings to our shelves. For that reason, we’ve opted for 16GB of their DDR4 Vengeance LPX Series 3200MHz RAM kit in our $400 build. This Memory leaves your PC in a good spot for any future upgrades and allows you to make the most of the 5600G we feature in this build. Remember that the CPU RAM and the VRAM become one when using an APU. So it’s not only the CPU that is dependent on this memory.
