Recommended Add-ons

Although not entirely necessary, some add ons like optical drives can sometimes improve your experience. Some, like an operating system, are significantly more crucial. If you’re installing your operating system from a disc opposed to a USB flash drive, then you’ll definitely need an optical drive.

  • windows 10

    Windows 10 (USB Installer)

    Windows 10 is your best bet when it comes to picking an operating system. This version is a USB installer. View

  • optical disc drive

    Samsung Ultra-Slim External CD DVD±R/RW

    External optical drives are quickly overtaking their internally mounted counterparts in both popularity and practicality, and it’s easy to see why! This one is definitely one of the cheaper & better options to consider. View

The tools you need:

That’s really all you need to assemble your new desktop. All of the mounting hardware and cables will come with the parts listed above. The only time you might need something extra is if you’re modifying the build on this page.

Build Breakdown

This might be one of the best $900 gaming PC builds out there, and it is going to easily run any game you can throw at it in 1080p. Most AAA games will run on ultra settings @ 60fps or better, but less graphically intensive games will run at well over 100fps.

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.

phanteks eclipse p300Case: Phanteks Eclipse PH300 is an awesome mid-tower ATX case. It gives you a handful of premium features without asking you to spend a premium price. It's equipped with a full PSU shroud and good cable management options for a clean build, a big tempered glass side panel, and overall good airflow options.

It comes with 3 fans so you likely won't need more.

Motherboard: The MSI B450-A Pro Max ATX motherboard is a great choice at this level that's loaded with all of the features you might need for an AM4 socket build like this; including 6x USB ports, 6x SATA ports + 1x M.2, integrated audio, 2 case fan headers, room for 4 sticks of RAM, a built-in ethernet controller and lots of room for future expansion.

The B450 chipset does support CPU overclocking, which means you're free to crank up the power on your R5 3600 assuming you have adequate cooling.

Processor (CPU): AMD's 3rd generation R5 3600 is a very strong 6-core/12-thread 4.2GHz processor that's basically perfect for a gaming PC like this one. Not only is it a solid CPU for gaming, but it's also great when it comes to work-oriented tasks as well. As a bonus, the R5 3600 comes with a good CPU cooler, but you can always replace it with something aftermarket if you'd prefer, or if you want to try some really intense overclocking - why not check out a list of the best CPU coolers?

rx 5700 graphics cardGraphics Card (GPU): AMD's new RX 5700 and its 8GB of GDDR6 VRAM is a complete and utter powerhouse when it comes to 1080p gaming - it's also capable of tackling 1440p without a problem while pushing 60fps in most games.

Gigabyte's RX 5700 Gaming OC is absolutely no exception. It runs quiet, cools great, has 4x display outputs (3x DisplayPort, 1x HDMI), and easily fits inside almost any case with ease. It's very capable of 1440p 60fps gaming in any game out there and it can easily support VR headsets like the Vive or Rift.

System Memory (RAM): 16GB of 3000MHz DDR4 RAM from Corsair's Vengeance LPX lineup is a perfect amount, and speed, for any gaming PC. Running 16GB ensures that you won't run into any RAM-related performance issues and allows for significantly more multi-tasking when compared to 8GB. As an added bonus, you won't have to worry about adding more anytime soon as it'll take games years to consistently start requiring more than 16GB of RAM.

However, if you need more than 16GB, you can easily add more. The motherboard in this build has 4 slots for RAM and only 2 are being used by the current 2x 8GB pair.

Power Supply (PSU): Thermaltake's 550W Smart BX1 is a good 80+ Bronze rated non-modular PSU with more than enough juice to power this build. Being that it's non-modular, it'll come with all of the cables permanently attached, it might not be ideal for achieving clean cable management, but you'll have everything you need regardless.

There are many other options in terms of different power supplies. They come in one of 3 configurations, non-modular like this one, semi-modular where only some cables are permanently attached, and fully-modular where no cables are permanent.

wd blue 500gb ssdStorage: The WD Blue 500GB SSD this build uses is a good start. For a lot of people, it might be all they need. If you're one of the people who need more than 500GB of storage, I have good news.

Adding more is really easy; all you have to do is grab another drive, plug in power + data and voila, you have more storage! This build can even support an M.2 NVMe SSD, if you wanted to try one of those out.

If you're on a budget of $900, you're in luck, because that's the perfect amount to spend on a DIY gaming PC build. If you were to go to Best Buy and pick a prefab PC up for $900, you wouldn't get anything near the level of this beast. Just, don't forgot the price of Windows and any peripherals you might need on top of that.

Operating System

The operating system you pick should be based on your necessities, or how much extra cash you have lying around. If you need something that works right out of the box with very little tinkering required, Windows is what you want, but keep in mind that it'll cost around $100 to go this route.

windows-10-homeWhen it comes to getting access to the widest range of compatible programs, games, etc, Windows is your best bet. There are a few options available, but the one you'll want to consider first is Windows 10. It's the only OS that supports DirectX 12, and you're definitely going to want DX12 as it becomes used in more and more games.

For the more frugal or privacy concerned users, a Linux based O/S like Ubuntu might just do the trick. Linux has been dubbed the "most secure" operating system when it comes to spyware, etc, so if that is a concern, it's just another reason to grab a free copy of Ubuntu.

When it comes down to actually installing your OS, you basically have 2 options. Either do it from a DVD/CD or create your own bootable flash drive loaded with an OS installer. In my opinion, the first option is a lot easier, but you'll need to grab the DVD drive I have listed above.


If you don't already have the base peripherals like a monitor, keyboard, mouse, and some kind of audio, you're definitely going to not only want these things, but need them. Below we've featured an awesome product to represent each of the fundamental extras that you might need!

Picking the best monitor for your usage is often very subjective, beyond the basic specs you should be looking for that is. With such a wide array of different designs and price points, it pays to do some research. That's why I put together this guide on how to pick the best monitor for gaming!

Even more important than picking a good monitor is picking a good chair. If you can't get comfortable because you're using a bad chair, you're simply not going to enjoy your gaming sessions as much as you should be. To ensure you can get the most out of every session, I put together this in-depth buyers guide of all the best gaming chairs!

To connect to the internet, your most reliable and fastest option is always through a wired connection, but if you have no other choice other than a WiFi connection, then you're also going to need a WiFi adapter.

If this is you, there are some important points you should consider before simply picking the cheapest adapter and calling it a day. First is the capabilities of your WiFi router/modem, does it support both 2.4GHz and 5GHz bands? Or just the 2.4GHz band? Determining this is your first step as it'll dictate which level of WiFi adapter will give you the best bang for your bucks.

Generally speaking, a router on the "N" standard (like N900, etc) will only support the 2.4GHz band, but AC adapters (AC1200, AC1300, etc) will support both the 2.4GHz and 5GHz bands, often simultaneously. So, is your router N or AC?

Once you've determined what kind of WiFi router you're working with, you can move onto picking out your adapter. Ideally, you want your router and adapter to be operating on the same "standard" (N/AC). To make it really easy, just pick an adapter with the same letters as your router/modem.

When everything is said and done, this machine is a beast and it will absolutely dominate any game you decide to play in 1080p 60-100fps+ (way more in most games) and it's also going to do well in 1440p @ 60fps. Whichever route you go, you can rest assured that this build has the power to handle it effectively.

If you came here looking to build the best $900 gaming PC that will last you into the future of modern games, you've found the right build. This beast features quite a bit of upgrade potential and a lot of raw power, so what are you waiting for?

If you have any questions, comments, concerns or otherwise, feel free to leave them in the comment section and I'll try to answer ASAP!

Hey Branton,

I’ve been looking to buy a pc to play Fortnite competitively. Do you by any chance know how well this pc would run Fortnite at pro settings? (100% resolution and all low settings except for view distance which is set to Epic). Also, would I be able to run Fortnite at 140fps consistently while streaming or using recording software? Thanks!

This is going to be my first pc build. I am going to use it for gaming maybe 1 or 2 at a time and some video editing for a YouTube channel I’m going to start. With the specs of this build I know it can handle it. But I do have a few concerns and questions. Sould I have a smaller ssd for my os and one for the games and video editing or will the constant uploading from my go pro reduce the life of an ssd? I’m at a loss as what to do for storage. Just need an idea please. Thank you. Kevin

Get a hard-drive for some of that extra storage, and I wouldn’t recommend this PC as it is more on the side of gaming rather than video/editing giving that the GPU would need to be updated and you need to add on a capture card, plus there wouldn’t be that much ram only 16G.

Hi Branton,

How well does this PC preform when it comes to streaming games? I’ve been meaning to get into it.

Hi Branton,

I am viewing this build in 2020 and I’m wondering if it’s appropriate for what I’m looking for. I’d like to play games like Skyrim, Batman Arkham series, Fallout 4, and etc. I know these aren’t the most intense games out there, so would this build be overkill (naturally I still want it to look good).
Btw, this is my first PC ever so do I need to purchase cables for the monitor (acer gn246hl)? People seem to say that the hdmi isn’t enough for high performance.
Also, would a second fan be necessary right off the bat? My budget is already stretched because of the peripherals so I’m not sure if I have much to spare.
Thanks for your advice

Hello Branton,

The case you put a link to got deleted, and the cheapest one available from a different seller was a 20$ increase (71$). So, I was wondering if you could give me a good case around the same price as the one you listed above (before it got deleted). Any help would be greatly appreciated! 🙂

Hello Branton,

I wanted to upgrade the processor to the pc so I found this one -

But in the description it says Compatible only with Motherboards based on Intel 300 Series Chipsets, so I’m wondering if it would work with the motherboard you listed –

Thank you!
