When prebuilts don't cut it or you finally have the chance to jump into PC gaming properly, building your own rig is the way to go. This gaming PC build guide is your guide for constructing a powerful rig to run your games and more. Below is a list of the best PC parts and components to slot into your dream gaming rig.

This guide is your reference for building a reliable gaming PC. You don't have to pick up every piece of hardware in this list, but each one will give you a good idea of what to look for and why certain things are better than others. PC building is about having fun and making something that caters to you; this list is a cheat sheet and by no means a rule book.

Speaking of budget, the cost for this gaming PC build is $1,000, with around $400 (keep an eye out for deals) reserved for an Nvidia GeForce RTX 3060 Ti that should provide an excellent framerate for most games at 1080p (and even 1440p). And with the help of upscaling tech like DLSS, 4K gameplay is within reach on some games. 

The Ryzen 5 5600X is the best choice for a CPU for this build because of its price, performance, and overclocking potential. However, if you are strictly in an Intel camp, Intel Core i5 12400 and B660 motherboards are good choices. Remember, you can get by with a smaller SSD or slightly slower RAM and upgrade those later to save a few bucks. 

The last thing you should know is that all the hardware on this guide are all things I'd want if I were building my own PC. Each component has been tested on the PC Gamer Test Bench and merits my full recommendation. If this isn't what you're looking for, check out our budget PC build guide and high-end PC build guide. Or skip the whole building thing and get a cheap gaming PC.


Ryzen 5 5600X processor in box

(Image credit: AMD)
AMD's top affordable, and available, Zen 3 CPU today


Cores: 6
Threads: 12
Base Clock: 3.7GHz
Boost Clock: 4.6GHz
Overclocking: Yes
L3 Cache: 32MB
TDP: 65W
PCIe 4.0 lanes: 20

Reasons to buy

Awesome gaming performance
Great value for money
Decent overclocking potential
Wraith Stealth included

Reasons to avoid

$50 more than 3600X
... 3600X came with a better cooler

When it comes to gaming, everything that's great about the 5900X rings true for this more affordable Zen 3 chip as well. There's nothing between any of the Ryzen 5000 chips in games, which means you'll hit the same frame rates with this chip as you will the much more expensive chip. Which is incredible when you think about it—top-tier performance from the most affordable Zen 3 CPU? We'll say yes to that every single day.

This does have half the core count of that top chip, rolling in as it does with 6 cores and 12 threads. This is only an issue with those more serious workloads, though, and this is more than sufficient for more reasonable stuff. You could argue that gaming could go beyond the 12-threads we have here, but there's no evidence that is the case so far, and that's even though the next-gen consoles are rocking 8-cores and 16-threads. 

The Ryzen 5 5600X also bucks the Ryzen 5000 family's trend by shipping with a Wraith Stealth cooler, so you don't have to drop extra money on a third-party chiller. You don't need to, but if you do, you'll hit higher clocks for longer and also open up the wonderful world of overclocking, which could make it worthwhile. This is a decent little overclocker, and while it won't affect gaming much, it'll help in other areas nicely.

The best B550 motherboard


Form factor: ATX
Memory support: 4x DIMM, up to 128GB, up to DDR4-4600
Expansion slots: 2x PCIe 4.0 x16, 1x PCIe 3.0 x4
Storage: 2x M.2, 6x SATA 6Gbps
Networking: Intel WiFi 6, Intel 2.5Gb ethernet, Bluetooth 5.1
Rear USB: 3x USB 3.2 Gen 2, 4x USB 2.0

Reasons to buy

Extensive feature set
Build quality
Top-end networking

Reasons to avoid

Pricey for a B550 board
Stock-clock performance is unremarkable

Sure, the Asus ROG Strix B550-E isn't the cheapest motherboard for a Ryzen 5 5600X chip, but it offers a huge amount of potential room for your PC to grow in the future. It's a premium motherboard, with all the trappings you'd expect from Asus' Republic of Gamers stables, such as 14+2 power stage, M.2 heatsinks, and pre-installed backplates. You also get Wi-Fi 6 wireless networking as well as Intel 2.5Gb ethernet too. And RGB LEDs, of course.

At a glance it cuts a convincing enthusiast dash thanks to copious heat sinks and spreaders, including one for each M.2 slot, snazzy LED lighting, and three full-length PCI Express slots, two of which come in Gen 4 trim.

Impressively, those slots support dual-GPU graphics, each in eight-lane PCIe 4.0 configuration, ensuring the maximum currently available bandwidth for high end graphics. A niche concern? Perhaps, but it's indicative of the ambitions of this board. Similarly, the Strix B550 has not just an eight-pin but also a four-pin supplementary CPU power supply connector. Again, that’s an indication of a board designed for high performance. 

Performance too is typically good for a high-end Asus board, matching X570 motherboards for gaming performance without issue. The Asus ROG Strix B550-E Gaming is the whole package then, and right now is our all-around pick for the best B550 motherboard.

A GPU that can take on the RTX 2080 Super... and win


GPU Cores: 4,865
Base Clock: 1,410MHz
Boost Clock: 1,665MHz
TFLOPS: 16.2
Memory: 8GB GDDR6
Memory Clock: 14GT/s
Memory Bandwidth: 448GB/s

Reasons to buy

4K performance
Decent ray tracing performance
Great cooler

Reasons to avoid

Impossible to find...
...stupidly expensive if you do

The RTX 3060 Ti is the GeForce card that we want in our mid-range machine. That was true last year, when buying one was almost impossible, but it's true today for another reason. The next-generation of Nvidia and AMD GPUs are just around the corner, but history tells us the first to launch will be the high-end GPUs. That means that mid-range and budget GPUs, such as the RTX 3060 Ti down to the RTX 3050, will stick around a lot longer before being replaced.

So if you want a great gaming PC now, and one that doesn't break the bank, the RTX 3060 Ti is one of the cards out there we'd still recommend.

It marks the same incredible generational leap in performance that has come to epitomize the Ampere architecture, up until the non-TI GeForce RTX 3060 (opens in new tab), that is. With performance that can often outpace the RTX 2080 Super, for a nominal $399 price tag, it's the mid-range card to beat.

And, because of its RTX 2080 Super performance levels, that means you can nail 1080p and 1440p frame rates, but also that 4K at 60fps isn't beyond the realms of possibility for this GPU. The RTX 3060 Ti then delivers gaming performance that's rather stupendous when you look at generational gains over even the RTX 20-series—next to the 10-series, it's quite frightening, actually.

Corsair Vengeance LPX 16GB (2x8GB) DDR4-3200

The best value RAM you can get


Capacity: 2x 8GB
Speed: 3200MT/s
Timings: 15-17-17-35
Voltage: 1.35V

Reasons to buy

High frequencies on a budget
Low latency too

Reasons to avoid

Lacks the RGB pretties

Memory is pretty straightforward these days, though if the price isn't much higher you can improve performance (opens in new tab) slightly with faster RAM. DDR4 prices have thankfully galvanized somewhat, with typical costs for 16GB often falling well below $100. There are many options to choose from: Adata, Ballistix, Corsair, Crucial, G.Skill, GeIL, Gigabyte, Hynix, HyperX, Micron, Mushkin, Patriot, PNY, Samsung, Team, and XPG are all good brands as far as we're concerned.

Our main goal for gaming memory is DDR4-3000 or higher, with as low a CAS latency as possible, but at a good price. It doesn't make a lot of sense to buy extreme memory for a mainstream build, but with DDR4-3200 only costing $10 more than basic DDR4 kits, it's worth paying a little extra for AMD builds (opens in new tab).

WD_Black SN770 1TB

Deent capacity and low cost makes the SN770 a winner


Capacity: 1TB
Interface: M.2 PCIe Gen4 x4
Sequential IO: 5150/4900MB/s read/write
Random IO: 740K/800K IOPS read/write

Reasons to buy

Decent capacity
Gen4 without breaking the bank 
Easy installation

Reasons to avoid

500GB is a viable option to save cash

You could spend more on a high-performance PCIe 4.0 SSD, but you can get awfully close to top performance with this SN770 from WD.

An NVMe M.2 SSD offers swift access to your data, and the SN770 delivers that snappy response at an exceptionally agreeable price. Fitted with 1TB worth of NAND flash, there's enough space for your operating system, applications, and plenty of games. So feel free to go wild downloading your favourite games on Steam. Well, not too wild.

If you wanted to save some cash, you could opt for the smaller 512GB version here. It's more agreeable on price, and your secondary storage could make up for lost capacity later down the line.

WD Black 1TB (Optional)

The quickest regular HDD, offering storage on a budget


Capacity: 1TB
HDD speed: 7200RPM
Cache: 32GB
Connectivity: SATA 6Gb/s
Warranty: 5 years

Reasons to buy

A cheaper storage option
Great reliability for a HDD
High capacity for files less often accessed

Reasons to avoid

Slow compared to SSDs

Given the install sizes of most modern PC games, it's probably a good idea to get yourself a new drive for your gaming PC. While SATA SSDs are almost cheap enough to recommend as secondary storage (what a world we're living in), you'll probably look to a regular HDD to keep the cost down when you hit multiple terabyte demands.

We recommend the WD Black drive because it's a 7,200 RPM drive with a respectable 32GB cache, which offers 1TB of storage for about $70 or less. While you could get a WD Blue or Seagate Barracuda for less, the WD Black offers speed and reliability over capacity. Realistically, you'll appreciate that speed if you're planning to keep your HDD inside a gaming PC for more than a couple of years, as we already see load times creep up for the biggest games of 2022. 


Corsair TX650M 650W power supply shot at an angle on a blank background

Corsair TX650M 650W

Highly reliable and efficient power without going overkill


Output: 650W
Efficiency: 80 Plus Gold
Connectors: 1x 24-Pin ATX, 1x 8-Pin (4+4) EPS12V, 4x 8-Pin (6+2) PCIe, 6x SATA, 4x Molex, 1x Floppy
Modular: Partial

Reasons to buy

Good efficiency and price
Sane output rating
All Japanese capacitors

Reasons to avoid

650W may not cover it for some super high-end GPUs down the line, but be realistic about whether that matters to you or not

Power supplies are not the most exciting part of a gaming PC build. After all, it can be hard to tell them apart in terms of features. Even so, you don't want to skimp on your PSU. Corsair has an excellent and well-deserved reputation for its power supplies, and the TX650M comes at a reasonable price and delivers 80 Plus Gold efficiency.

Most power supplies from the bigger names are generally good, but we wouldn’t recommend that you put your money in anything with a warranty of fewer than five years or an efficiency rating below 80 Plus Gold (maybe Bronze in a pinch). The $10 or $20 saved often isn't worth the risk (opens in new tab).

We also tend to go with modular PSUs where possible. It means less cable mess inside the case since you don’t have to stash unused cables somewhere. Instead, the remaining wires have to find a home in your closet.

Here's our guide to the best power supplies for PC (opens in new tab) gaming.

Reasons to avoid

Getting on a bit

Cases can be as stylish or boring as you want. We're going to go for the former rather than the latter, with the NZXT H510, a slick, tempered glass case available in white or black. The NZXT H510 is also reasonably priced, which is always a bonus. 

If you want other options, check our guide to the best mid-tower cases (opens in new tab). The clean look goes well on any desk and doesn't stand out like many so-called 'gaming cases.' There's also the pricier H510i that integrates some smart features if you like the look of the H510 but want a few more bells and whistles.

Picking a case can be an entirely personal choice, so for more options, here are the best PC cases (opens in new tab) you can buy right now.
