This $400 budget beast is a MOBA/CS:GO powerhouse and will often beat consoles when it comes to AAA games. It's packing a lot of power for a small price and also gives you lots of room for future upgrades!
In this budget build you get an AMD R3 2200G, a 2GB RX 560, 8GB of RAM, and 240GB of SSD storage. There's a ton of room for expansion in almost every way. You could add more storage, more RAM, a better CPU, stronger GPU. I think you get the picture.
Games like DOTA2 or CS:GO and any other popular esports or indie game will run great on this build. When it comes to graphically intensive and AAA games this build won't do max settings but it will put out good performance on low-mid settings - comparable to the Xbox One and PS4 consoles (not the X or Pro).

Building a budget gaming PC for around $400 is a really challenging thing to do, to do it right that is. You have to balance power with price, and it has to be done well. This build is a good example of positive balance.
Keep in mind that the price above is for the core components only, you will still need an operating system, and any other peripherals you don't currently have.
Case: This ultra-budget gaming PC build is running a fairly basic case from Rosewill. Their SRM 01 is a basic mATX case with the most basic options you need for this build. It has enough room for everything and even comes with a single fan.
Motherboard: The ASRock B450M Pro4 is a good mATX-sized motherboard that delivers all of the features you'll need for an AM4 socket build like this; including the ability to support processor overclocking.
With it, you're getting integrated audio, a built-in ethernet controller, plus 4x SATA headers and 1x M.2 ports for storage, basic 2.1-channel audio, a total of 8 USB ports, and enough fan headers to support this build.
The B450M Pro4 is also one of the few "budget" B450 chipset boards to feature actual heatsinks on the VRMs.
Processor: AMD's 2nd generation Ryzen 3 2200G is a powerhouse when it comes to sheer performance for the price you're paying. It's a 3.7GHz quad-core beast and one of the few AMD processors to include an iGPU. It's capable of keeping up with all 1080p-grade graphics cards and is quite comparable to Intel's i3 lineup.
The R3 2200G comes with a pretty good Wraith Stealth CPU cooler from AMD, but if you're going to be overclocking it would be wise to upgrade. If that's you, check out the best CPU coolers!
Graphics Card: The 2GB RX 560 is a decent 1080p-grade graphics card. It's definitely on the lower-end, but can still deliver console-like performance and above. Sapphire's RX 560 Pulse is no exception and offers one of the best price vs performance ratios on the market today. It gives you great cooling options, a good ability for overclocking (for an RX 560) and a low-profile low-noise design.
RAM: When it comes to RAM, 8GB is the baseline for any gaming PC build in 2019. With that in mind, this build is running 8GB of 2666MHz DDR4 RAM in a dual channel configuration of 2x 4GB sticks.
If you want to add more RAM, you should know that the motherboard will support 2 more sticks; ideally, they should be the same speed.
Power Supply: There are a lot of high-performance parts in this build, so its fair if you're assuming its going to need a gigantic power supply, but luckily it won't! At most this build will only use a few hundred watts of power, so an 80% efficiency 500W supply will do the trick just fine. I've picked Thermaltake's Smart 500W 80+ Bronze PSU which is a good budget option offering more than enough connections for everything you need, it also comes with a decent 5-year warranty just-in-case the worst were to happen.
Storage: For storage, I opted to load this build with a 240GB SSD. For one, SSDs are significantly faster than HDDs - the difference is mind blowing if you haven't used one. For two, 240GB is often more than enough space to get a build up and running and install a handful of games.
Luckily, storage is the easiest part of a gaming PC to "upgrade". It's simply a process of plugging a new drive in and voila, you have more space.
I didn't pull any punches when it came to squeezing every ounce of power from your $400 budget, and this build will not disappoint! When it comes to building your own gaming computer for $400, this is undeniably your best option.
The operating system you choose is going to depend on how much you have to spend, or how much you want a legitimate copy of Windows.
Windows is the most common choice, and because this build is running a Skylake processor, you're going to want to look at Windows 10. It's going to give you access to the widest range of compatible games & programs while running really smoothly. It's come a long way since launch, and it's definitely worth checking out. But, it's your build, so you can pick whichever version you're most comfortable with.
Ubuntu is a great option for a lot of people for the main reason that it’s entirely free. It's a Linux-based operating system that will allow you to play quite a few games, but not everything that Windows would.
When it comes to actually installing your operating system, you have pretty much 2 options. You'll have to either install it from an optical drive or create your own bootable flash drive with a Windows installer.
The first option is obviously a lot easier, and doesn't require any additional time, but you're going to have to make sure you grab the DVD drive linked above. If you want to make your own bootable flash drive, you can find instructions here.
If you don't already have the basic peripherals to go with your new PC, you're definitely going to want them. You're going to need a mouse, keyboard and a monitor - at least. Headphones or some kind of speakers would also be a good idea.
If this is the scenario that you're in, then we have some really awesome suggestions for you to consider. The keyboard and mouse we've featured might be from a brand you haven't heard of, but Redragon makes some really awesome peripherals that retail for way less than you would expect.
23.6″, 1080p 60Hz, 2ms response time – Great for gaming View
CM Storm Devastator 3 KB+M Combo
An awesome keyboard + mouse combo from Cooler Master for around $30!
Creative SB Blaze
Good sound quality, a solid mic, and a budget-minded price are 3 things you get from the Creative SB Blaze.
If you plan on using a WiFi connection, then you're also going to need some kind of WiFi adapter as very few motherboards come with it built-in.
You have a couple of options, either a USB-based WiFi adapter, or one that mounts internally, but you only need one. USB is more convenient and much cheaper in most cases, but they're often less reliable than an internally mounted unit.
If you came here looking to build yourself a kickass and cheap gaming PC for $400, I hope you found what you were looking for. The power this build puts out is nothing to scoff at, and it's definitely going to outperform your PS4 or Xbone.
This is definitely a console competitor and it's going to give you quite a bit of power in a nice space-saving package. I set it up so you can easily upgrade components as they go on sale or get cheap - better yet would be to wait until you have the $ saved for a slightly higher priced build.
All-in-all, you will be hard pressed to build a better gaming PC build for around $400. It's cheap, it's compact, and it's relatively powerful.
