While you could simply buy one of the best gaming PCs out there, putting together your own system can be less expensive and much more rewarding. When you put together a system yourself, you have total control over everything, from how many RGB fans you want, the make and model of the motherboard to the aesthetics of the chassis.
This build-a-gaming PC won’t recoil at the challenge of pushing through high FPS at 8K. But, of course, it’s going to cost you. Still, this beast will be made of the best CPU for gaming coupled with the best graphics card and will cost you less than buying a whole new system. Let’s take a look at 2021’s best PC parts.
Building A Gaming PC – PC Custom Parts
Intel Core i9 10900K ($469.99 VIEW AT AMAZON)
Cores: 10 | Threads: 20 | Base Clock: 3.7GHz | Turbo Clock: 5.3GHz | Overclocking: Yes | L3 Cache: 20MB | TDP: 125W | PCIe 3.0 lanes: 16
The AMD Ryzen 9 5950X is a more worthy option thanks to its 16 cores and 32 threads of processing power, but it’s almost impossible to get your hands on one right now. Your next best option is the Intel Core i9 10900K. Don’t get us wrong, Intel’s gaming performance lead is still unmatched, and the 10900K, with 5.3GHz all-core overclocking chops, is still one of the best when it comes to pure frame rates. Of course, you’ll need a proper motherboard, serious cooling, and a mighty PSU to get the most from it, but we’ll get to those in a minute.
Asus ROG Maximus XII Extreme ($1,363.63 VIEW AT AMAZON)
Chipset: Z490 | Memory: 4x DIMM, 128GB, DDR4-4800 | Expansion slots: 2x PCIe 3.0 x16 (x16 or dual x8), 1x PCIe 3.0 x4 | Video ports: 2x mini DisplayPort | USB ports: 12x rear IO, 6x internal | Storage: 4x M.2, 8x SATA | Network: 10Gbps Ethernet, Intel Wi-Fi 6 | Lighting: 2x Aura RGB, 2x Aura addressable Gen 2
Up for a quick tech anatomy lesson? If the CPU is your PC’s brain, the motherboard is its nervous system that optimally keeps things running.
The Asus ROG Maximus XII Extreme operates the Z490 chipset, which means it’s designed to handle Intel’s 10th gen (and possibly later gens) processors. In addition, the beast features no less than four M.2 slots for you to get crazy with, support for Thunderbolt 3 on an extra add-in card with two mini DisplayPort connectors.
The best part is that you get access to 10Gbps and 2.5Gbps Ethernet and Wi-Fi 6 (aka 802.11ax) wireless connectivity. In addition, there are tons of USB ports, and, of course, the RGB lighting is compatible with a collection of Aura Sync peripherals.
Nvidia GeForce RTX 3090 (CHECK AMAZON)
GPU Cores: 10,496 | Boost Clock: 1,695MHz | Memory: 24GB GDDR6 | Memory speed: 19.5Gbps | Memory Bandwidth: 936GB/s
Serious gamers, If you want two graphics cards, at least for Nvidia Ampere, the RTX 3090 is your only option. This is still a $1,499 graphics card, and that’s if you net the Founder’s Edition and not a pricier third-party job. It’s the only RTX 30-series card furnished with the required connection for an NVLink bridge, but most games don’t support SLI even with that fixed.
Before committing, there are a few key concerns you’ll need to consider to make the most of it. For starters, it’s “designed” for 8K gaming, with a bit of help from Nvidia’s AI super sampling tech, DLSS. However, to do that, you’ll want one of the few 8K gaming monitors equipped with HDMI 2.1, VRR support, and high refresh rates.
Moreover, the RTX 3090 is a power-hungry card, and when coupled with the Core i9 10900K, you really want to make sure your PSU is up to the task. We recommend a PSU capacity of at least 1000W and one from a reputable manufacturer that can also offer high operational efficiency.
G.Skill 32GB TridentZ DDR4-3200 RGB (4x8GB) ($189.99 View at Amazon)
Capacity: 4x 8GB | Speed: 3200MT/s | Timings: 16-18-18-38 | Voltage: 1.35V
We absolutely love the look of G.Skill’s TridentZ RGB sticks. In addition, RAM prices have been diving lately, meaning you can now get a 32GB kit for well under $200. Besides G.Skill, you can also go for Corsair, Kingston, HyperX, Crucial, Adata, and Team as reliable picks. Most RAM modules work well, so it always comes down to price—and color, if you’re into that.
Sabrent Rocket Q 4TB ($599.98 VIEW AT AMAZON)
A tiny SSD with a whole lot of speedy storage space
Capacity: 4,096GB | Interface: M.2 PCIe 3.0 | Sequential read/write speed: 3,200MB/s / 3,000MB/s | Random IOPS: 550K read / 680K write
The Sabrent Rocket Q 4TB drive carries a tremendous amount of storage into a small SSD. Still, it maintains performance on par with MLC drives. The Sabrent’s exceptional speed and range imply you can have a fast, spacious SSD boot drive without compromising a slower data storage option. So if you want to have all your games downloaded at any point, the Sabrent Rocket Q is an incredible drive. And if you’re feeling spendy, there’s the spectacular Sabrent Rocket Q 8TB drive too. Here are the best SSD for gaming options out right now.
EVGA SuperNova 1000 G5 ($224.11 VIEW AT AMAZON)
Output: 1,000W | Efficiency: 80 Plus Gold | Connectors: 1x 24-Pin ATX, 2x 8-Pin (4+4) EPS12V, 8x 8-Pin (6+2) PCIe, 12x SATA, 4x Molex, 1x Floppy | Modular: Fully
As a wise gamer, you don’t want a cheap PSU taking down the rest of your system.
The EVGA SuperNova 1000 G5 is a great option to build an extreme rig around when it comes to power supplies. This beast offers up to 1000W of power for your new build to turn into lightning-smooth gaming experiences. If you only intend to operate using a single GPU, or a lower-tier CPU, EVGA’s SuperNOVA 850 T2 is an excellent option that will save some bucks. If you’re really short on funds, the SuperNOVA 850 P2 is every bit as good.
NZXT Kraken X62 ($159.99 VIEW AT AMAZON)
Size: 280mm | Fan speed: 1,200rpm | Airflow: 55.4 CFM | Noise level: 20.4 dB(A) | Dimensions: 315 x 143 x 29 mm | Socket support: LGA115x, LGA2011, LGA2066, AM2, AM3, AM4
We highly recommend liquid cooling when trying to get the most out of Intel’s enthusiastic chips. The NZXT Kraken X62 is an impressive piece of tech that works with all major platforms. It’s pretty easy to install and features a massive 280mm radiator and a pair of 140mm fans. However, even with the X62, you may run into temperature limitations. So if you’re a serious gamer looking to push the i9 10900K beyond its limits, consider getting a fully custom liquid cooling loop.
While we fully support gamers that build their own computers, not everyone is up for that kind of challenge. And, of course, that’s completely fine. If you’re not up for it, feel free to check out more build guides to help you find the right components for your system.
