*Hardware prices change daily, sometimes multiple times in a single day. Therefore, the price listed above should only be considered a rough estimate.
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.

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 (USB Installer)

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

  • Kingston A400 120GB SATA SSD

    An SSD is a great way to speed up load times and decrease boot times. 120GB will be enough for your operating system and a couple games.

  • 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.

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.

Case: Corsair's Spec 02 is a great mid tower ATX case that doesn't break the bank. It offers great airflow for ample cooling and comes with 2x 120mm fans plus has room for liquid cooling radiators up to 240mm. There's an acrylic window on the side panel that offers good visibility into your case, but it gets scratched easily. The cable management is pretty okay, but it could be better and if you spent another $30 or so you could get a case with much cleaner cable management.

When it comes to cases, pretty much any mid tower ATX case will work well for this build, feel free to use another one if you'd like to. Since the motherboard in this build is micro-ATX by default, you could also use an mATX case if you really wanted to.

Motherboard: MSI's B450M Bazooka 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 8x USB ports, 6x SATA ports + 1x M.2, integrated audio, room for 4 sticks of RAM, a built-in ethernet controller and lots of room for future expansion.  This chipset does support CPU overclocking, which means you're free to crank up the power on your R5 2600.

Processor (CPU): AMD's 2nd generation Ryzen 5 2600 is a strong 6-core/12-thread 3.9GHz 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 2600 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?

Graphics Card (GPU): The GTX 1070 and its 8GB of GDDR5 VRAM is a complete and utter powerhouse when it comes to 1080p gaming and it's even capable of 1440p without a problem. EVGA's GTX 1070 SC Gaming 8GB is absolutely no exception to this rule. It runs quiet, cools great, has 5 display outputs, and easily fits inside almost any case with ease. It's very capable of 1080p 60fps gaming in any game out there and it can also support VR headsets like the Vive or Rift.

System Memory (RAM): 8GB of 2666MHz DDR4 RAM from Kingston's HyperX Fury lineup is a good starting point for a dedicated gaming PC, running a dual channel pair will give you plenty of room to upgrade to 16GB when it comes time. That being said, running 16GB of RAM would help with multitasking and that might be something that you want to consider - especially if you're looking into possibly streaming or you just like to do a lot of things at once.

Power Supply (PSU): EVGA's 600 BQ is a reliable semi-modular power supply that has more than enough juice to power this build. It boasts an efficiency of up to 85% and packs a 3-year warranty just in case anything were to ever happen to it, which is unlikely.

Storage: 1TB of internal storage is pretty decent, but it's honestly not ideal. To fit the GTX 1070, I had to sacrifice either the 1TB HDD or the 250GB SSD that used to be loaded in this build - I opted for more storage over faster storage, but you're completely free to go the opposite route. Check out my post on the differences of an HDD vs SSD if you want to learn more about storage.

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

  • Acer GN246HL

    24″, 1080p 144Hz, 1ms response time – Great for gaming!

  • Corsair K55 RGB

    An awesome RGB keyboard using rubber dome keys. Lots of tactile feedback.

  • Razer Mamba Tournament Edition

    Chroma RGB lighting, awesome sensor accuracy, very comfortable to use.

  • Corsair HS50

    Easily one of the best headsets for under $50

  • Logitech Z623 2.1 sound system

    2.1 channel, 200W RMS/400W peak. If you like bass, these are the speakers+sub you want.


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.

  • TP-Link TL-WN722N

    A very affordable N150 USB WiFi adapter. Capable of 150Mbps on the 2.4GHz band

  • TP-Link Archer T4U V3

    A reliable AC1300 USB WiFi adapter. Capable of operating on both the 2.4GHz and 5GHz bands.

  • Rosewill AC1300 PCIe WiFi Adapter

    A good internally mounted (PCIe) AC1300 WiFi adapter.


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?

Would another tower work with this build I don’t like the look of this one and any recommendations?


Does this build support dual monitors or no?


-Intel i5-8500
-Arctic Freezer 33 eSports One CPU Cooler
-Asus ROG Strix B360G Gaming mATX
-Team Vulcan 2x8GB DDR4 3000Mhz RAM
-Western Digital WD10EZEX
-Kingston A400 120GB SSD
-MSI GeForce 1070 Ti 8GB GPU
-Corsiar CXM 550W 80+ PSU
All in a CoolerMaster MasterBox Q300P mATX Case

How does this look? Will 550W get the job done? My wattage estimation is roughly 359W according to PCparticker.


What does “integrated audio” mean?


Does the stock cooler come with thermal paste?


Sorry for the amount of questions,does the power cord come with any of the parts?


I worded that horribly,do any of the parts come with a power cord?
