Adamant Custom 24-Core Ultra 9 285K 128GB DDR5 1TB NVMe RTX 5090 gaming PC

24-Core Workstation for AI and Rendering

This desktop pairs a 24-core Intel Core Ultra 9 285K with 128GB of DDR5 memory and an Nvidia GeForce RTX 5090 32GB GPU. The configuration targets professionals running local AI inference, complex 3D rendering, and multi-application workloads that demand high thread counts and large video memory. A 360mm liquid cooler keeps the processor stable under sustained load.

Samsung 990 PRO SSD and 1200W Gold PSU

The 1TB Samsung 990 PRO PCIe 4.0x4 drive delivers sequential reads up to 7450 MB/s and writes up to 6900 MB/s, reducing project load times and texture streaming bottlenecks. The Thermaltake Toughpower 1200W 80 PLUS Gold unit provides certified efficiency headroom for the 5090 and 24-core CPU combination, with Japanese main capacitors and full protection circuits.

PCIe 4.0 Storage Ceiling and Mid-Tower Constraints

The Z890 motherboard wires its M.2 slots to PCIe 4.0 lanes, capping any current or future NVMe drive at the 990 PRO's 7450 MB/s read ceiling; PCIe 5.0 storage cannot operate at its rated speed on this platform. The Ceres 300 mid-tower fits the 360mm radiator and RTX 5090, but its 475mm depth and 245mm width leave no room for a second full-length graphics card or additional 3.5-inch drive bays beyond the single convertible bay.
