The Intel Core i9-12900KS is now one of the best processors for gaming money can buy. You are guaranteed blistering desktop performance and incredible FPS in-game, with zero chance of throttling.

Now on the LGA 1700 socket, this i9 features 16 cores and 24 threads. The cores are split into eight performance cores and eight efficiency cores and this can hit up to 5.5GHz in boost.

The ASUS ROG Strix Z690-F may not be the best the chipset has to offer but this is well-balanced and provides an excellent base for your next-generation components.

This board supports 128GB of DDR5 memory that can run up to speeds of 6400MHz. We also see 16+1 power stages, Thunderbolt 4, PCIe 5.0 support, and Wi-Fi6E. All in all, a great board with impressive connectivity supporting HDMI 2.0 and DisplayPort 1.4 output, quad M.2, USB 3.2 Gen 2×2 Type-C, Type-A, and Front panel USB 3.2 Gen 2×2 Type-C connectors.

The Corsair iCUE H150i Elite Capellix is magnificent for CPU cooling and it achieves this by being virtually silent in the process.

The cooling potential of the H150i matches the competition and this 360mm option is perfect for the Core i9-12900KS in this build, with the RGB fans and pump only adding to the overall aesthetics. You may need to contact Corsair for the LGA 1700 cooler bracket upon buying this.

This 32GB kit from G.Skill offers a future-proof amount of memory and some impressive speeds to go with it. Of course, Intel’s performance doesn’t really dwell on RAM Speed as much as AMD but with this kit, you are set for one incredible system.

The Trident Z DDR5 RAM kit comes with two 16GB sticks capable of running at speeds of 6600MHz, so you are never going to be bottlenecked by your RAM.

To match the almighty power of the 12900KS, we think an RTX 4070 Ti GPU provides a great performance to match. In that case, the GPU brings the latest and greatest features to enjoy. With some great efficiency and features like frame generation for the use of DLSS 3, you really do get plenty from the card.

Having fast storage has become quite the gaming necessity, improving load times, boot times, and generally making our lives a lot easier.

This gen4 NVMe SSD is one of the fastest in its class, with read and write speeds of up to 7000/500MB/ s respectively. We’ve opted for a 2TB model, giving you plenty of room for your operating system, games, and general media files, without the necessity for adding another storage device.

Corsair is a huge name in the PC case world and their iCUE 5000X mid-tower is one of the best currently available. Aside from offering high-end build quality and functionality, we have three tempered glass panels and three 120mm RGB fans, giving you the perfect place to house your new build.

Every good PC worth its salt needs a reliable PSU to keep things ticking over. We have a 750W model from Corsair here, with full modularity and a gold-rated level of efficiency, giving you all the reassurance and power you need.

Intel 12th gen gaming PC price

The overall cost can be quite staggering but this is down to the base of this build featuring the next-gen of parts. To save money, you could opt for the lesser-powered Core i7-12700K and pair it with a more affordable Z690. You could also go for a lower-speed RAM kit, while still taking advantage of DDR5, and could grab a cheaper PC case with a more affordable PSU too.

We wanted to build the best Intel 12th gen PC here but we understand that only a minority of gamers can actually afford such luxuries. Another way to save money would be to go for an RTX 3060Ti, however, we wouldn’t recommend pairing this with the i9 CPU shown in the build above, as it would be better suited to an i5-12600K.
