GeekaPC 'Apex' (RTX 5080)

The GeekaPC 'Apex' is a powerful gaming PC for those looking to play their favourite AAA games at 4K. This system is housed inside a black Phanteks NV5 MK2, a gorgeous dual-chamber chassis with two tempered glass panels and integrated RGB. This system is equipped with the NVIDIA GeForce RTX 5080, an incredibly powerful card built to handle the intensity of 4K gaming.

As the brains of this PC build, handling all of your everyday tasks and workloads is the AMD Ryzen 7 9800X3D. This is one of the most powerful gaming CPUs, equipped with AMD's almighty 3D V-Cache designed to uplift performance in your favourite games. This CPU features eight cores and sixteen threads at a whopping boost clock speed of 5.2GHz, a perfect pairing for the NVIDIA RTX 5080.

Ensuring thermals are under control is the Phanteks Glacier D360. This is a black 360mm liquid cooler that utilises magnetic fans that connect together via daisy-chaining. They offer RGB on the outer chassis of the fan and on the fans, and provide ample cooling for the AMD Ryzen 7 9800X3D.

Providing a home for all of the PC components in this PC build is the Phanteks NV5 MK2. This is a case we've used a number of times in the past due to its robust design, simple build assembly, and fantastic aesthetic. This chassis features an RGB strip on the power supply shroud, and comes shipped to you with Phanteks D30 fans on the side, bottom and rear panels.

For the RAM, we've stuck with a firm favourite across many of our builds, the Corsair Vengeance RGB kit. This is a powerful and reliable RAM kit and provides gamers with additional RGB lighting. Those looking to increase the performance of this build even further also have the option to upgrade from 32GB to 64GB.
On the storage front, the Apex PC build is equipped with either a 1TB Samsung 990 Pro or Crucial P310 as standard, providing read speeds up to 7000MB/s, and writes up to 6000MB/s. Both drives offer very similar performance and are ideal for those looking to minimise load and boot times. If you're running out of space for your favourite games, you also have the option to increase the capacity from 1TB up to 2TB and 4TB for those that need plenty of storage room.

Last but not least is the Corsair RM850e. This is an incredibly reliable and efficient 850W power supply, providing all of the juice for this build. Its Cybenetics Gold efficiency rating ensures that any additional power draw will be minimised across the board.

This build has a dedicated video on the GeekaWhat YouTube channel where the host, James Cousins, details the entire step-by-step process. He covers each component's pros (and cons), along with a suite of gaming benchmarks at the end, providing an idea of how this system performs.

*Note: The GPU model shown in the video and attached photos is the NVIDIA GeForce RTX 5080 Founders Edition card. GeekaPC reserves the right to use any model of the RTX 5080 as selected, depending on real-time availability.
