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.

Questions about this item

Does the PC ship with the Corsair 4000D case, liquid cooler and 1200W PSU already installed, or must I buy any of them separately?

The system arrives fully assembled inside the Corsair 4000D tempered-glass mid-tower with the 360mm AIO liquid cooler and Thermaltake Toughpower 1200W 80 PLUS Gold PSU pre-installed; no extra case, cooler or power supply purchase is required.

Should I choose the 128GB DDR5 configuration or the maximum 192GB supported by the four memory slots?

The board has four DDR5 slots populated with 128GB; if your rendering, modelling or AI workloads regularly exceed that capacity you can add modules later up to the 192GB limit, otherwise the shipped 128GB is sufficient.

What does the RTX 5090 32GB GPU mean for 4K gaming and AI training once the PC is running?

The 32GB frame buffer lets you run modern 4K titles at high settings and train large AI models locally without offloading to system memory, while the 24-core Core Ultra 9 285K at up to 5.70 GHz keeps the CPU side from bottlenecking those tasks.
