Adamant Custom Ultra 9 285K RTX 5090 64GB 8TB Gaming PC

Built for rendering and AI workloads

This Adamant Custom tower pairs a 24-core Intel Core Ultra 9 285K with an Nvidia GeForce RTX 5090 32GB GPU and 64GB of DDR5 memory. An 8TB NVMe array built from two Samsung 990 PRO drives feeds data at up to 7450 MB/s read and 6900 MB/s write. A 360mm liquid cooler and a 1200W 80 PLUS Gold PSU keep the system stable under sustained compute loads. Windows 11 Pro ships pre-installed.

Suits creators and researchers needing local GPU

The 32GB frame buffer on the RTX 5090 lets large models and high-resolution assets stay resident without offloading to system RAM. Builders who need more than four memory slots or who want ECC support should look elsewhere, as the Z890 UD board provides four standard DDR5 slots only. Users without 2.5Gb Ethernet or Wi-Fi 6E infrastructure will not benefit from the onboard network controllers.

64GB DDR5 handles multi-app creative pipelines

The installed capacity runs modern editing, modelling and inference tasks comfortably, while the motherboard supports up to 192GB for future expansion. Storage headroom is generous at 8TB of high-speed NVMe, though the case offers only two 3.5-inch and two 2.5-inch internal bays for additional drives. The 1200W power supply delivers ample headroom for the current GPU and CPU, but leaves no margin for a second high-end graphics card.
