Best Gaming PC Under 900

Nine-hundred dollars affords us some serious firepower in the world of computing- keep reading to find out which parts we will need to build the ultimate best gaming computer under $900.

In a $900 budget, we can afford to pick from some of the latest and greatest processors from the Intel family. It may be tempting to look at something from the 5000 lineup, but we’re going to stay a bit more grounded here and select the Ryzen 5 3600 from AMD legendary Ryzen 3000 series. Renowned for their affordability and uncompromising performance, the 3000 line has long been a favorite for gamers looking to get the most out of their dollar, and the AMD Ryzen 5 3600 is one of the best AMD has to offer. 

This is one of the processors that sits above the rest in the lineup. This AMD Ryzen processor is built with 6 Cores for their consumers, with 12 threads paired with the AMD wraith stealth cooler. The 3600 operates at a base clock of 3.6GHz with a max turbo boost of up to 4.2GHz. 

These features are nice to have, but will largely be helpful for the tasks we wish to accomplish. We’re going to have more than enough horsepower to run the latest games and applications.

The Ryzen 3600 is great for gaming and amazing when it comes to performing multiple tasks.

2) MSI Performance Gaming AMD Ryzen 2nd & 3rd Gen AM4 M.2, B450

Our processor, the AMD Ryzen 3600, needs a newer, compatible motherboard from AMD's series 3000 specification. For this task, I’ve picked out the MSI Performance Gaming,B450 Max, a famous offering from MSI’s series of “MAX” Motherboard lineup. 

The B450 packs all the standard features: Dual Channel 64GB DDR4, Non-ECC Unbuffered DDR4, and Intel WiFi.

The B450 Gaming Max, has no Thermal Heatsink or inbuilt bluetooth but With 4 PCIe Express slots, and 1 PCI slot, and many more added features, you have enough to work around with. 

You may recognize this guy from, well, probably all of my other builds. It’s true, I’m a fan; I’ve rarely used much else in my computers, and occasionally I’ll see a different brand’s standard memory sticks with better timings or a bit less on the price tag, but I always come back to Corsair. The Vengeance is especially a solid unit with a long and storied past of use by consumers across the market, with solid performance and a typically low rate of busted RAM. You can do worse, though I’ll say, as you may be interested in something similar from G.Skill or Crucial who usually make good stuff, be prepared to do a little research and make sure you get something at the best speed and performance mark for the price you pay.

As before, the LPX DDR4 Ram is a low-profile stick compatible with most motherboards and setups in general, with little to no effort needed to make them work with any system. It also comes in a few different colors, and like any other RAM stick, can easily be upgraded by buying a second one at any time down the road and slotting in place next to the first. If you want to start off with better RAM built in, look choose this two-pack, kit cheaper than buying two sticks separate.

4) Western Digital 500GB WD Blue 3D NAND Internal PC SSD

At $900, we’re finally going to be able to get some serious speed in our gaming pc build. The addition of an SSD (Or Solid-State-Drive) is going to dramatically decrease our boot-up times and loading times for certain applications and games. The only drawback of SSD’s is their low capacity and high price. Don’t worry though, we’ve found the right balance between the two. However, we’re going to quickly talk about some more traditional storage first.

Because of the limited size of more affordable SSD’s, we’re going to need an auxiliary hard drive. (Also known as an HDD or “Spinning Disk” Hard Drive.) These “spinning disk” drives have the advantage of being a tried-and-true technology, and their age means savings for us. Hard drive prices continue to fall, and I can’t think of a better example for this phenomenon than the WD Blue 3D. 

This deal just keeps getting better and better. With a 2.5” form factor, it’s a compact hard drive for a compact price.

Now onto the fun part, the SSD. Due to their high price-per-gig, high-capacity SSDs some might believe not to be a good idea for any gaming pc build at this range. But with current change in times and availability of more quality branded ones in the market, I am going to use a smaller, more affordable, 500GB SATA III SSD from WD.

The WD Blue 3D NAND is an affordable package at around 50 bucks,  but don’t let its affordability fool you. This SSD is packing sequential read and write times of 560MB/s and 530MB/s, respectively, which places it firmly in the competition among rival manufacturers like Corsair. The 2.5” size means we’re going to have plenty of space to share with our secondary drive.

Adding this SSD is going to take our OS boot times from minutes to seconds, just remember if possible to set up your documents, pictures, movies, and music folders, so they are routed to your secondary drive.

Planteks is a brand I’ve come to rely on a number of times in my build history, I’ve never had a part of theirs let me down. The Eclipse is a really solid deal, especially for the price point. Plus, it has a surprising wealth of optional little features for something in the eighty-dollar-or-under range, such as a fully equipped magnetic dust filters, free cable management loops, adequate space for drive bays and storage are just a few of those features. In fact, it even comes stock with two built-in 120mm fans (at the front and rear), perfect for the starter who doesn’t want to have to worry about upgrading them, and a cheaper starting point for fan enthusiasts who want to add a couple more.

And though it might not matter, it’s a very attractive case, with available tempered glass to showcase those LED lights and neat set-up. On the plus side–and more importantly–it feels and is built well; none of the parts feel cheap, and it’s overall a pretty sturdy case. I’d recommend it. Obviously, as this is a recommendation.

The components in our $900 build are estimated to use about 400+ watts altogether. This does not mean we can use a 300 watt power supply. We need something that’s going to comfortably supply enough power to our components at a consistent rate, and to that end I’ve selected the Thermaltake Smart BX1.

The Thermaltake Smart BX1 will provide us enough power for our current components as well as enough power for any upgrades or additions down the line. It accomplishes this with an 80+ Bronze certification, which means the power supply is at least 80% efficient at all times. An excellent certification to look out for when considering budget power supplies. I also enjoy the sleek aesthetic of Corsair’s power supplies. The Smart BX1 features an all black, metal housing, and black sleeving for the cables. The simple banner on the side fits perfectly with the theme of our case, motherboard, and other components. 

The thermally-controlled fan maintains low-RPM operation when your system is idle and only kicks on to full when the temperatures rise. 

The final piece of the puzzle, the cherry on top- the graphics card. In a $900 budget, we’ve finally got a little bit of room to breathe when making our selection, and room to breathe is certainly something we need in this hellish market of crypto mining and inflated prices. To that end, we’re going to choose the Gigabyte RX 5700 Gaming OC for our $900 PC Build. 

8 GB is going to be more than enough to provide high FPS for both1080p and 1440p. PowerColor AMD is the right reliable high performance pick.

We’re finished! We’ve been able to work with our budget of $900 and  built an absolute monster of a PC. This build will utterly dominate with max settings at 1080p, 1440p, and should carry you pretty far into the 4K territory if you tune your settings appropriately. The extra cores in our processor are going to make multitasking, intense workloads, and multi-core-bound games a breeze. That extra processing power is also going to come in handy when we combine it with the 6GB of video memory in our graphics card. That’s right, our $900 Gaming Computer build is VR ready.
