Custom Workstation for AI and Rendering

This Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K with an Nvidia GeForce RTX 5080 16GB GPU and 64GB of DDR5 memory. It targets professionals running local AI learning workloads, complex 3D modelling scenes and high-resolution video editing. The 8TB NVMe array and liquid CPU cooling support sustained compute throughput in a tower form factor.

Suits Single-GPU Compute; Not Multi-GPU or More VRAM

The single RTX 5080 16GB configuration fits workflows that scale across CPU threads and one accelerator. Buyers who need a second graphics card for render farms or simulations should look elsewhere. Users requiring more than 16GB of video memory for massive textures or LLMs will find the GPU frame buffer limiting.

8TB NVMe Storage Decides Fit

Two 4TB Samsung 990 PRO drives deliver up to 7450 MB/s reads and 6900 MB/s writes over PCIe 4.0 x4. That capacity and speed combination determines whether the system ingests raw footage and model checkpoints fast enough. If the project library exceeds 8TB or demands sustained writes beyond the quoted peaks, a larger or faster array is required.

Questions about this item

What clearance does the 360 mm liquid cooler need inside the Corsair 4000D case?

The 360 mm radiator fits in the top or front of the Corsair 4000D, which measures 490 mm deep, 239 mm wide and 486 mm high, leaving room for the 140 mm fans and tubing.

Which motherboard power cables must be seated for the Core Ultra 9 285K on the Z890 UD?

Connect the 24-pin ATX and both 8-pin EPS cables from the Thermaltake 1000 W unit; the CPU will not post if either EPS connector is missed.

How many M.2 slots remain free after the two 4 TB Samsung 990 PRO drives are installed?

The Z890 UD provides four M.2 connectors; two are occupied by the 4 TB drives, leaving two open for future NVMe upgrades up to the board's 192 GB memory limit.
