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.

Questions about this item

Does the Thunderbolt 4 port on the Z890 motherboard carry full 40 Gbps bandwidth?

The rear Thunderbolt 4 Type-C port supports up to 40 Gbps, matching the Thunderbolt 4 specification for display and data.

Will the 240 mm liquid cooler fit inside the Corsair 4000D case without blocking the RAM slots?

The 240 mm AIO mounts at the front or top of the 4000D; both positions clear the four DDR5 slots on the TUF Z890 board.

Do I need to install any drivers before the integrated graphics will output to HDMI or DisplayPort?

Windows 11 Pro installs the Intel graphics driver automatically; connect the monitor to the rear HDMI or DisplayPort and it will display immediately.
