Workstation core

This Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K with 64GB DDR5 and an Nvidia RTX PRO 4000 Blackwell GPU. The combination targets engineers and creators who need strong multi-thread compute and certified drivers for SolidWorks, CAD, CAM and CAE workloads. Windows 11 Pro ships pre-installed on the 4TB NVMe boot drive.

Build foundation

A TUF Gaming Z890-PLUS motherboard provides four DDR5 slots, four M.2 connectors and four SATA ports, so the 64GB kit leaves three memory slots open for expansion up to 192GB. The 360mm liquid cooler and 850W 80 PLUS Bronze PSU are already fitted inside the Antec P20 mid-tower, which offers front-panel USB 3.2 Gen 2 Type-C, 2.5Gbps LAN and Wi-Fi 7 connectivity.

Storage and graphics headroom

The 4TB Samsung 990 PRO NVMe drive delivers up to 7450 MB/s reads for active project files, while a 10TB HDD with 256MB cache holds bulk archives. The RTX PRO 4000 Blackwell carries 24GB VRAM, giving ample frame-buffer for large assemblies, though buyers needing more GPU memory or a second card would need a different platform.

Questions about this item

How long can the 360mm AIO liquid cooler keep the 285K CPU at its 5.70 GHz boost before thermal throttling?

The 360mm quiet-edition AIO is designed to dissipate the 285K's sustained heat load, allowing the 24-core CPU to hold its 5.70 GHz maximum turbo frequency during extended workloads without hitting thermal limits.

What noise level does the 140mm PSU fan and 360mm AIO produce when the system runs 24/7 at full load?

The Thermaltake 850W Bronze PSU uses a 140mm ultra-quiet fan and the 360mm AIO is a Quiet Edition model; together they keep acoustic output low even when the 285K and RTX PRO 4000 run continuously at peak power.

Which display cables must I already own to use the RTX PRO 4000's video outputs?

The RTX PRO 4000 Blackwell uses standard DisplayPort and HDMI connectors, so you only need the corresponding DisplayPort or HDMI cables that match your monitor inputs.
