You might be thinking that it'll take a lot of tools to build a PC... But that's not the case.
To build a PC, you generally only need 1 tool, a #2 Phillips screwdriver. However, there are a couple of other items that might help make the build go a little smoother.
- #2 Phillips Screwdriver
- Anti-static wristband
- Small flashlight
How To Build Your PC – Simplified Steps

- Mount your RAM – make sure they click!
- Mount your CPU cooler – Don’t forget thermal paste

Complete Build Breakdown
This $900 gaming PC build is guaranteed to give you amazing 1080p performance and great 1440p performance as well. In 1080p, you’ll be able to run practically every game out there on ultra settings while seeing at least 60fps. In 1440p, this build will readily handle high to ultra settings in, again, every game that’s currently released.
Case: NZXT’s H510 is a great mid-level case that gives you all of the necessary features that you’ll need for this build. That includes a spacious layout which lends to clean cable management and plenty of options for cooling.
The H510 comes with 2x 120mm fans by default which is good enough for a basic cooling setup, but more fans can be added as needed. There are 3 color options available with this case, black, black & red, and white.
CPU & Cooler: AMD’s R5 3600 is an incredible mid-level CPU that has no issues handling heavy gaming. It’s packing 6 cores and 12 threads with a default clock speed of 4.2GHz. This CPU does come with a CPU cooler, but you can expect it to run quite warm under load while using the stock cooler.
Our suggestion when running the AMD R5 3600 is to switch out the stock cooler for something a little more beefy.
MOBO: The ASRock B450M Pro4 is a solid mATX motherboard with all of the options required for this build. It’s equipped with 4x SATA ports for storage, 4x DIMM slots for RAM, and a total of 8 USB ports including Type-C.
GPU: When it comes to mid-range graphics cards, the RTX 2060 is a solid choice depending on the price. If you can find one for less than $320 then it’s undeniably a great choice.
The Zotac RTX 2060 used in this build isn’t the absolute highest-quality option, but it’s priced well and is still an RTX 2060 at the end of the day.
RAM: When it comes to building a gaming PC, 16GB of RAM is basically a must in 2020. You could get by with less, but your performance would be impacted in most newer games.
With that in mind, this build is running 16GB of Corsair’s Vengeance LPX clocked at 3200MHz. This RAM doesn’t offer up any RGB lighting, but it does offer great performance for an awesome price.
PSU: Power supplies are undeniably one of the most important parts of a PC. Without a strong power supply running quality components, you run the risk of damaging your parts. At the very least, you want a power supply that is rated 80+ Bronze.
The PSU used in this build is a 550W 80+ Bronze rated unit from Corsair’s CX-M lineup. This supply is semi-modular which means only some of the cables are permanently attached, making for cleaner cable management.
Storage: This build is running a basic storage setup comprised of a single 500GB SSD. This isn’t a huge amount of storage, but it’s enough to get going and install a handful of games. Adding more storage drives is simple and only requires that you simply plug it in.
Keyboards, Mice, and Audio
Picking out a keyboard, mouse, headphones/speakers, and everything else you might need for a complete PC setup can be difficult. Not only that, but it can be completely overwhelming since there are just so many options available.
With that in mind, here are some suggestions which I feel are suited for this level of build. All of them have been hand-picked to compliment the build on this page.
A good full sized mechanical keyboard with RGB backlighting and a very attractive price point.
Logitech G502 HERO
One of the absolute best gaming mice you could buy. The G502 is a tried and true platform that’s only been improved to where it’s at now with the HERO.
