20-Core Workstation for AI Tasks

The Adamant Custom desktop ships new with a 20-core Intel Core Ultra 7 265K processor, 128GB of DDR5 memory and a 1TB Samsung 990 PRO NVMe drive. Windows 11 Pro is pre-installed on the Z890 TUF motherboard. The system targets professionals who need high multi-thread throughput and AI-ready performance in a single chassis.

Liquid-Cooled ATX Build with Front I/O

A 240mm quiet-edition AIO cooler handles the CPU while a 750W 80 PLUS Bronze unit with a 140mm fan supplies power. The Corsair 4000D tempered-glass case provides front USB 3.2 Type-C, two USB 3.2 Gen 1 ports and an audio combo jack. Rear connectivity adds Thunderbolt 4, USB 20Gbps and 10Gbps ports, 2.5Gbps LAN, Wi-Fi 7 and Bluetooth 5.4.

Upgrade Path from Lower-Core or Air-Cooled Systems

Four DDR5 slots support up to 192GB, and four M.2 connectors plus two 3.5-inch and two 2.5-inch bays allow storage expansion. Integrated graphics drive HDMI and DisplayPort outputs, so the platform suits compute workloads that do not require a discrete GPU. Buyers needing dedicated graphics acceleration or more than 192GB of memory should consider a different configuration.
