A 24-core Intel Core Ultra 9 285K workstation with Nvidia RTX PRO 4000 Blackwell graphics, 64GB DDR5, 1TB NVMe and 10TB HDD in a liquid-cooled tower
The Adamant Custom tower pairs a 24-core Intel Core Ultra 9 285K processor with an Nvidia RTX PRO 4000 Blackwell graphics card. It ships with 64GB of DDR5 memory, a 1TB NVMe SSD and a 10TB hard drive. Windows 11 Pro is pre-installed and the system is liquid cooled.
Engineers running SolidWorks, CAM or CAE workloads gain 24GB of GPU memory and 64GB of system RAM for large assemblies. Buyers who only need high frame rates in games will find the professional GPU and workstation drivers unnecessary. The four memory slots allow expansion to 192GB if datasets grow.
The NVMe drive delivers up to 7450 MB/sec read and 6900 MB/sec write for active projects. The 10TB hard drive provides deep archival capacity with 256MB cache. Memory headroom reaches 192GB across four slots, so heavy simulation scenes can scale before a platform change is required.
Measured against everything we stock in Gaming PCs, at today’s prices. Recalculated every night.
New to this? Buying a gaming PC with crypto — what to check, what it costs to pay, and what is never asked for.
