24-Core AI Workstation

The Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K processor with an Nvidia GeForce RTX 5090 graphics card and 64GB of DDR5 memory. It ships with Windows 11 Pro and an 8TB NVMe storage array built from two 4TB Samsung 990 PRO drives. The system targets professionals running rendering, modelling and AI learning workloads.

Liquid-Cooled Tower Build

A 360mm liquid cooler handles the CPU while the Ceres 300 mid-tower case uses four 140mm fans rated at 1500rpm and 30dBA for airflow. The Thermaltake Toughpower 1200W 80 PLUS Gold power supply includes over-voltage, under-voltage, over-power and short-circuit protection. Front I/O provides one USB 3.2 Gen 2 Type-C, two USB 3.0 and HD audio; the rear adds Thunderbolt 4, USB 20Gbps and 10Gbps ports alongside 2.5Gbps LAN, Wi-Fi 7 and Bluetooth5.4.

Platform Limits and Expansion

The Z890 motherboard supports up to 192GB of DDR5 across four slots and offers four M.2 connectors plus four SATA 6Gb/s ports for additional drives. The case accepts one 3.5-inch or two 2.5-inch bays for supplementary storage. Buyers who need more than 8TB of high-speed NVMe capacity or a second graphics card will find the current configuration restrictive.

Questions about this item

What Thunderbolt 4 bandwidth does the rear Type-C port provide?

The rear Thunderbolt 4 Type-C port delivers up to 40 Gbps for displays, storage and docks.

What case clearance is needed for the 360 mm liquid cooler?

The Ceres 300 mid-tower fits a 360 mm radiator at the front or top; allow 475 mm depth, 245 mm width and 463 mm height.

How are the two 4 TB Samsung 990 PRO drives installed, and what step is often missed?

Both drives slot into the motherboard M.2 sockets; the common miss is forgetting to remove the protective film on each thermal pad before securing the screws.
