24-Core Ultra 9 Workstation

This Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K processor with 64GB of DDR5 memory and an Nvidia GeForce RTX 5080 graphics card. A 4TB Samsung 990 PRO NVMe drive provides primary storage. The system ships with Windows 11 Pro installed and uses a 360mm liquid cooler on the CPU.

Suited for rendering and AI workloads

The 24 cores, 64GB DDR5 and RTX 5080 16GB combination handles 3D modelling, video editing and local AI inference. Builders who need more than 64GB of memory or multiple graphics cards should look at a different platform. The mid-tower chassis and single 1000W power supply limit internal expansion.

4TB NVMe and 192GB memory ceiling

The Samsung 990 PRO delivers up to 7450 MB/s reads and 6900 MB/s writes, feeding large project files without bottleneck. Four DIMM slots support up to 192GB total DDR5 for heavier datasets. The single GPU configuration caps graphics memory at 16GB, so workloads needing more VRAM will require a different system.

Questions about this item

Does the Corsair 4000D case include the required 400mm radiator clearance for the 360mm AIO liquid cooler?

Yes, the 4000D supports up to 360mm radiators in the front panel, matching the installed 360mm Quiet Edition AIO exactly.

Will the Z890 UD motherboard’s four DDR5 slots and 192GB maximum let me keep and expand the 64GB kit later?

The board has four DDR5 slots with a 192GB ceiling, so the existing 64GB kit occupies two slots and leaves room for two more modules.

How can I confirm the Samsung 990 PRO 4TB SSD is delivering its rated 7450 MB/s read and 6900 MB/s write speeds after setup?

Run CrystalDiskMark or AS SSD Benchmark; sequential read should approach 7450 MB/s and write 6900 MB/s on the PCIe 4.0x4 link.
