24-Core Ultra 9 Workstation

This Adamant Custom tower ships with a 24-core Intel Core Ultra 9 285K processor, 64 GB of DDR5 memory and an Nvidia GeForce RTX 5090 graphics card with 32 GB of video memory. It targets professionals who need heavy parallel throughput for rendering, modelling or AI training workloads. Windows 11 Pro is pre-installed.

Upgrade Path From Older Workstations

The system replaces an ageing workstation that struggles with modern multi-threaded render queues or large dataset processing. The jump is worth it when current projects exceed the memory or GPU VRAM limits of the older machine and deadlines demand faster frame output.

Compatibility Checks Before Ordering

Verify that the 447 mm depth, 215 mm width and 469 mm height fit the intended desk or rack space. Confirm the 1200 W power supply matches the available mains circuit and that the front-panel USB 3.2 Gen 2x2 Type-C port meets peripheral connection needs.

Questions about this item

What case dimensions and drive bays does the Adamant Custom Ultra 9 285K tower use?

The chassis measures 447 x 215 x 469 mm and provides two 3.5-inch and two 2.5-inch internal bays for storage expansion.

How is the 360 mm liquid cooler mounted, and what step is often missed?

The 360 mm AIO radiator installs in the front of the case; the step often missed is connecting the pump header and PWM fan cables to the motherboard before closing the panel.

Which components can be upgraded later and what are the limits?

Memory can be expanded to 192 GB across four DDR5 slots, and the two 3.5-inch bays plus two 2.5-inch bays accept additional SATA drives; the board also has two free M.2 slots for NVMe SSDs.
