24-Core i9-14900K Workstation

This desktop pairs a 24-core Intel Core i9-14900K with 128GB DDR5 and an Nvidia GeForce RTX 5090 32GB GPU. Liquid cooling and a 1200W 80 PLUS Gold PSU support sustained workloads. Windows 11 Pro is pre-installed on a Corsair 4000D tower with WiFi6 and Bluetooth 5.2.

Suits AI, Rendering and Modelling Builds

Buyers who need 24 cores, 128GB memory and a 32GB GPU for local AI training, 3D rendering or complex simulation will match this spec. Users who only game at 1080p, need ECC memory or require more than 8TB of fast storage should evaluate other configurations.

32GB VRAM on RTX 5090 Decides Fit

The graphics card provides 32GB of video memory, which determines whether large models or high-resolution textures fit entirely on the GPU. If your workload exceeds that VRAM limit, the system will swap to system memory and performance will drop.

Questions about this item

Will the 360 mm liquid cooler fit in the Corsair 4000D case?

The 360 mm radiator mounts in the front or top of the 490 mm deep Corsair 4000D, leaving room for the 140 mm fan and tubing clearance.

What is the first step when installing the 128 GB DDR5 kit on the Z790 PRIME board?

Seat all four modules in the labelled slots until the retention clips click, then enable the XMP profile in BIOS before booting Windows.

Which component will need thermal-paste renewal first, the CPU block or the GPU?

The CPU water-block paste typically dries after two to three years; the RTX 5090 uses a factory vapor-chamber that rarely requires service.
