20-Core AI Workstation

The Adamant Custom desktop pairs a 20-Core Intel Core Ultra 7 265K processor with 64GB DDR5 memory and an Nvidia RTX PRO 4000 Blackwell GPU. It targets engineers, researchers and educators who need certified drivers for SolidWorks modelling and local AI inference. The system ships with Windows 11 Pro 64-bit and 2.5G Ethernet for wired network integration.

Sustained Load Behaviour

A 240mm liquid cooler handles the CPU while a 140mm PSU fan and three 120mm case fans move air through the Pop Air chassis. The 850W 80 PLUS Bronze supply delivers stable power under continuous compute workloads. Two 4TB Samsung 990 PRO drives provide up to 7450 MB/s read and 6900 MB/s write speeds for large dataset streaming.

Installation Notes

The ATX motherboard occupies the full case width, so the four M.2 slots and four SATA ports sit behind the long GPU; route cables before seating the card. Front-panel USB 20Gbps Type-C and 5Gbps ports connect to mid-board headers that face the drive cage. The 10TB HDD fits one of two 3.5-inch bays, leaving the second bay free for expansion.

Questions about this item

How loud and hot does the 240mm liquid cooler and 850W PSU run during extended workloads?

The system uses a 240mm Quiet Edition AIO liquid cooler for the CPU and a Thermaltake Smart 850W 80 PLUS Bronze PSU with a 140mm ultra-quiet fan; front and rear 120mm RGB fans provide case airflow.

Which display cables and monitor inputs do I need for the RTX PRO 4000 Blackwell GPU?

The graphics card occupies a PCI Express x16 slot and drives displays through its own video outputs; a compatible monitor with matching inputs such as DisplayPort or HDMI is required and not included.

Can I keep my existing 3.5-inch SATA drives and USB 2.0 peripherals with this Z890 motherboard?

The motherboard provides four SATA 6Gb/s ports for 3.5-inch drives, two front USB 5Gbps ports, rear USB 5Gbps and 2.0 ports, plus internal USB 2.0 headers for legacy devices.
