Adamant Custom Intel Core Ultra 9 285K RTX 5090 128GB DDR5 4TB NVMe 10TB HDD Gaming PC

Built for 24-core rendering and AI workloads

This Adamant Custom workstation pairs an Intel Core Ultra 9 285K with an Nvidia GeForce RTX 5090 32GB GPU and 128GB of DDR5 memory. A 4TB Samsung 990 PRO NVMe drive and a 10TB HDD provide fast primary storage plus deep capacity. The system ships with Windows 11 Pro on a Gigabyte Z890 UD motherboard inside a Corsair 4000D mid-tower case.

Suits creators who need 128GB RAM

The 128GB kit fills every slot on the board, so builders who plan to expand to the 192GB maximum must replace modules rather than add them. The 360mm liquid cooler and 1200W power supply handle the factory configuration, but buyers who want more storage bays than the two 3.5-inch and two 2.5-inch internal mounts should look at a larger chassis.

Arrives fully assembled

The 360mm AIO is pre-mounted to the CPU, eliminating the most error-prone step of a custom loop. The only common issue is transit vibration loosening the GPU bracket or a power cable; reseating the card and checking the 12VHPWR connector before first boot resolves it. Motherboard Wi-Fi 6E and Bluetooth 5.3 antennas screw into the rear I/O panel in seconds.
