best gaming pc build under 900

Looking to build yourself the best $900 Gaming PC possible? This might just be it. Featuring an i5 7500, an ASUS B250 motherboard, 8GB of DDR4 RAM, a Gigabyte GTX 1060 Windforce and 1.27TB of storage, you’ll be “future proof” for quite a while.

Building a gaming PC with around 900 dollars gets you something that will run the newest games on high-ultra settings in 1080p, and will also deliver very favorable 1440p performance in the majority of AAA titles – GTA:V on Ultra in 1440p would easily maintain 60fps!

This powerful PC is going to put you ahead of the game by giving you way more performance than you’re paying for. But, keep in mind that the price is for just the tower, if you need other peripherals or an operating system, those will be separate from the price listed below.

If you’re trying to build a gaming PC with a brand new Kaby Lake CPU and a powerful graphics card like the GTX 1060, this is definitely the build that you’re looking for!

  • A couple different styled/sized screwdrivers
  • Anti-static wristband (optional but suggested)
  • Patience

Putting your PC together is a lot easier than it sounds, and it’s easily something that you can accomplish by yourself. The build process is actually pretty straight-forward, and it’s honestly as easy as matching shapes together.

The only tools you need are a couple of smaller screwdrivers and a some(see: “tonnes of”) patience. Plugging parts like your graphics card and RAM sticks in won’t require any tools, and you’ll just need to make sure they’re going in the proper way and then firmly press until they click.

Static electricity is something else you should keep in mind, as it could easily fry your system if not kept in-check. An anti-static wristband can easily keep you static-free, and working on hardwood/tile/linoleum is usually a good plan also.

But, watching a video walkthrough always helps, so we’ve added one of those in the next tab!

Here are the basic steps that I follow when building:
  1. Install the Power Supply into the Case
  2. Install the processor (make sure the arrows line up)
  3. Install RAM (make sure they are in the right way before you try to seat them!)
  4. Mount the CPU cooler
  5. Place the rear I/O plate
  6. Mount the motherboard to the case (get your i/o ports through and use the middle standoff as a guide)
  7. Plug your GPU in
  8. Install any storage
  9. Plug everything into the appropriate spots
  10. Turn it on / Install OS & drivers!

Video Walkthrough

Instead of me typing out a ton of of words to explain this process, why not watch this video put together by He does a great job of explaining everything in detail, and is going to get you running in 30 minutes.

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 (USB Installer)

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

  • Crucial MX300 M.2 SSD 275GB

    SATA-based SSDs are pretty fast, but they simply cannot compete with M.2-based SSDs like the Crucial MX300!

  • 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.


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.

NZXT’s S340 case gives us a rigid, secure and good looking house to mount all of our shiny new hardware in. It allows for decent airflow and it also gives us plenty of expansion slots for fans, storage & optical drives. It comes with 2 120mm fans already installed, but you’re free to edit that how you see fit. There’s also other color options available. One thing to note is that there’s no 5.25 inch optical drive bay for DVD drives and things like that in this case.

Gigabyte’s GA-B250-HD3 motherboard is a great choice at this level that’s loaded with all of the features you might need, including 6xUSB ports, integrated 7.1 audio, a built-in ethernet controller and lots of room for future expansion.

Intel’s brand new i5 7500 is a really strong mid-level processor that’s perfect for a gaming PC like this one. Based on the new Kaby Lake architecture, the 7500 boasts a core clock of 3.4GHz and a 6MB Smart Cache.

gigabyte-gtx-1060-g1The GTX 1060 and its 6GB of GDDR5 VRAM is a complete and utter powerhouse when it comes to 1080p gaming, and the Gigabyte GTX 1060 Windforce is absolutely no exception. It runs quiet, cools great, 5 display outputs, and it comes with a clean looking backplate. It’s easily capable of 1080p 60fps gaming in any game out there and it can also support VR headsets like the Vive or Rift.

8GB of 2400MHz DDR4 RAM from Crucial’s Ballistix Sport LT lineup is really all we need for a dedicated gaming PC, and running a dual channel pair will give you plenty of room to upgrade to 16GB when it comes with. Personally, I run 16GB to help with multitasking, and that might be something that you want to consider as well if you’re looking into streaming or you just like to do a lot of things at once.

EVGA’s 650 GQ power supply is a really strong unit that has more than enough juice to power this build. It boasts an efficiency of up to 92% and is semi-modular so you really only have to connect the cables that you’re going to use.

1.27TB of internal storage is pretty decent, you shouldn’t run short anytime soon. 1TB of 7200RPM HDD storage and 275GB on an SSD is a good start for pretty much, anyone. With that said, you should definitely install your operating system on your SSD, as well as any games you plan on playing regularly. Everything else can go on your HDD without a problem.

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.

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” you might need!

  • Asus VS238H-P

    23″, 1080p 60Hz, 2ms response time – Great for gaming

  • Azio MGK1

    Solid mechanical keyboard using Kailh blue switches. Great tactile feedback!

  • EVGA TORQ X10 Carbon

    Wired, adjustable weight & height system, ambidextrous (use either hand).

  • Creative Sound BlasterX H7

    The Sound BlasterX H5 is easily the best gaming headset for under $100 and it’s not going to let you down!

  • Reflex Lab Mouse Pad

    Super smooth, very accurate, and extremely comfortable to use! Reflex Lab mouse pads are available in 4 sizes from your basic 9″ x 8″ right up to a whopping 36″ x 18″!


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.

You could get a decent USB-based WiFi adapter for around $20 and it would work alright. Or you could get an internally mounted WiFi adapter for about $35 and it would be more reliable than the USB option. The decision is yours!

  • TP-LINK TL-WDN4800

    Internally mounted WiFi adapter. 2.4GHz or 5GHz.


    USB WiFi adapter. 2.4GHz


When everything is said and done, this machine is a beast and it will absolutely dominate any game you decide to play in 1080p 60fps (way more in most games) and it’s also going to do extremely well in 1440p if that’s more your thing. 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!

    1. Hey Mike,

      That mobo is meant for old AMD CPUs and won’t work with the 7th gen Intel CPU in this build, unfortunately.

  1. how hard would it be to install 16 gbs of ram instead of the standard 8 also could this run doom 2016 on any settings thanks

    1. Not hard at all, Ethan! It’s just a matter of buying another 8GB set (or a 16GB kit) and plugging them all in!

  2. Hi! This was a really helpful guide, but I am having issues with regards to the GTX 1060. The graphics card seems to be a bit too big for the case I’m using and I wanted to know if this is abnormal or not? To preface this, I’m not using the NZXT S340 Mid Tower Computer Case, Glossy Black because it shipped too slow for my tastes, but I instead used something that should basically be the same thing, the NZXT S340 Razer Edition Computer Case , Matte Black. They’re the same model and I didn’t think there was such a difference in size, so… I guess what I’m asking for is guidance on this. Should I buy the black case because the minor difference evidently matters or is this just an issue that commonly comes up?

    1. Hey ZJ,

      That’s definitely strange because the standard S340 supports up to 364mm (14.3″) GPUs (without a liquid cooling radiator mounted at the front) and the Gigabyte GTX 1060 is 223mm (8.8″); as far as I know the Razer variant shares the exact same dimensions as the “standard” models and only the aesthetics are different. It’s very abnormal that your card isn’t fitting as lots of builds have been done using variants of the S340 and much longer cards (10″ and up) – could you provide a pic showing where your card is getting hung up?

  3. Can you give me a few alternative cases that will allow me to fit DVD also would you know what fps this would run Overwatch in ultra settings? and would this be the go to pc for me. I will be playing games alot of overwatch uploading and editing videos and possibly streaming

  4. Hey Branton it’s me again lol but I’m thinking of buying this pc I already bought ur 1000$ build and I’m looking unfit buying this one as a back up do u think this can run rainbow six seige ultra high fps and other games like the division and more games high fps

    1. Hey Mark,

      It’ll definitely run R6: Siege and The Division on ultra @ 60fps+, as well as pretty much every other AAA game! To get higher fps than that you’ll need to upgrade the graphics card to a GTX 1070.

      Hope that helps!

  5. Case: Corsair r200 or r300
    Video card: asus radeon rx 480 8gb rog strix
    Memory: 16ram with corsair vengeance
    Are these changes considerable?

  6. Hello,

    I am looking to do my first PC build. I’m looking to stream and i mostly play league of legends. Not sure what range i need and what all is needed. As i said I’m new :(. What could you recommend for building a nice PC able to run top end games and stream without any problems for a reasonable price. Not sure if this build is too much or not enough.

    1. Hey Eric,

      This build will work well for streaming LoL or anything like it. A couple of upgrades I might suggest to make your stream that much better would be adding another 8GB of RAM and subbing out the i5 7500 for an i7 7700 if you can afford it.

      Hope that helps!

  7. Hi, im looking to build this amazing build you have created as it seems perfect for my budget and what i’m looking for! I was just wondering what the different versions of the motherboard you stated do and if I could use them as well? For example GIGABYTE GA-B250M-DS3H or GIGABYTE GA-B250M-D3H

    1. Hey Rob,

      The biggest differents between those various motherboards are the form factor (micro ATX vs ATX) and the number of onboard headers for different components/addons. You could ultimately use any board you like as long as it has roughly the same options as the one I’ve linked to.

  8. This is my first ever computer build. I just wanted to know the average amount of time it takes for all of the parts to come in, and then the time that it makes to build the actual computer.

  9. Hi, I think i an going to build this PC. Looks great!
    But this will be my first gaming PC and i was wondering how this PC would work with Rainbow six siege? 1080p 60fps?
