Custom-built gaming workstation

The Adamant Custom desktop pairs a 24-core Intel Core i9-14900K processor with an Nvidia GeForce RTX 5090 graphics card. It ships with 64GB of DDR5 memory and 8TB of NVMe storage across two Samsung 990 PRO drives. A 360mm liquid cooler and a 1200W 80 PLUS Gold power supply support the high-end components inside a Corsair 4000D tower case.

Creators and AI developers needing maximum local

The 24-core CPU, 32GB GPU VRAM and 64GB system memory suit 3D rendering, video editing and large-model AI workloads. Buyers who only play games at 1440p or 4K will not use the full capacity of this specification. Teams requiring ECC memory or multi-GPU scaling should look at workstation-class platforms instead.

32GB GPU VRAM decides fit for large-model work

The RTX 5090 provides 32GB of video memory, which determines whether large language models or high-resolution textures fit entirely on the card. If your workflow needs more VRAM than 32GB, this configuration cannot meet that requirement.

Questions about this item

What does the i9-14900K’s 6.00 GHz boost clock mean for actual workloads?

The 24-core CPU can hit 6.00 GHz on light threads, giving snappy single-thread response, while the 360 mm liquid cooler keeps sustained all-core speeds high for rendering or compile jobs.

How does the Z790 chipset and PCIe 4.0 limit the RTX 5090 and Samsung 990 PRO drives?

The motherboard provides PCIe 4.0 lanes, so the RTX 5090 and both 4 TB 990 PRO SSDs run at their rated 4.0 speeds; no PCIe 5.0 bandwidth is available on this platform.

Will the Corsair 4000D case fit the 360 mm radiator and the RTX 5090 together?

Yes, the 4000D supports a 360 mm front radiator and has 490 mm depth, leaving room for the RTX 5090 and the 1200 W PSU without clearance issues.
