Adamant Custom Core Ultra 9 285K Workstation

This Adamant Custom gaming desktop PC targets creators and AI developers who need a 24-core Intel Core Ultra 9 285K processor, 128GB DDR5 memory and an Nvidia GeForce RTX 5090 32GB GPU.

Check Motherboard Connectors And Case Clearance

Verify that your existing peripherals match the rear I/O: one USB4 Type-C, one USB 3.2 Gen 2, four USB 3.2 Gen 1 and four USB 2.0 ports. Internal front-panel headers provide one USB Type-C, two USB 3.2 Gen 1 and four USB 2.0 connections. The mid-tower Corsair 4000D case measures 490 x 239 x 486 mm and holds two 3.5-inch and two 2.5-inch drive bays. Four M.2 slots and four SATA 6Gb/s ports remain on the Gigabyte Z890 UD motherboard for future storage expansion.

360mm Liquid Cooling And 1200W Gold PSU

A 360mm quiet-edition AIO cooler handles the CPU thermal load while a 140mm fan in the Thermaltake Toughpower 1200W unit keeps power delivery quiet. Japanese main capacitors and over-voltage, under-voltage, over-power and short-circuit protection underline build quality. The tempered-glass side panel shows the black interior. Integrated Realtek 7.1 audio, Intel 2.5Gb Ethernet, Wi-Fi 6E AX211 and Bluetooth 5.3 cover daily connectivity without add-in cards.
