24-Core Workstation for Professional Modelling

This Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K with an Nvidia RTX PRO 4000 Blackwell GPU carrying 24GB of video memory. It ships with 32GB of DDR5 RAM, a 4TB NVMe SSD and a 10TB hard drive. The system targets engineers and designers running SolidWorks, CAD, CAM or CAE workloads that demand both high single-thread frequency and certified professional graphics drivers.

Pre-built Liquid-Cooled Chassis

The PC arrives fully assembled in an Antec P20 mid-tower with a 360mm AIO cooler already mounted on the LGA 1851 socket. A Thermaltake 850W 80 PLUS Bronze unit powers the build through standard ATX cables. Builders adding drives must use the two internal 3.5-inch bays or the two 2.5-inch bays; the four M.2 slots on the TUF Z890 motherboard are occupied by the boot SSD, leaving no spare M.2 connectors for extra NVMe devices without removing the existing drive.

32GB DDR5 with 192GB Ceiling and Dual High-Speed

The 32GB kit fills two of four DDR5 slots, leaving headroom to reach the platform maximum of 192GB. The 4TB Samsung 990 PRO delivers sequential reads up to 7450 MB/s and writes up to 6900 MB/s for active project files, while the 10TB hard drive with 256MB cache stores archives and bulk datasets. When simultaneous GPU compute and large-assembly RAM usage exceed the installed 32GB, the system will page to the NVMe drive, increasing latency.

Questions about this item

How do I confirm the 24-core Intel Core Ultra 9 285K is running at up to 5.70 GHz after setup?

Open Task Manager or HWMonitor to view the CPU clock speed; under load it should reach the rated 5.70 GHz boost across the 24 cores.

What components are included and what must I purchase separately?

The box contains the complete PC with Antec P20 case, 850 W PSU, Z890 motherboard, 32 GB DDR5, 4 TB Samsung 990 PRO NVMe, 10 TB HDD, RTX PRO 4000 Blackwell 24 GB GPU, liquid CPU cooler, Windows 11 Pro, Wi-Fi 7 and Bluetooth 5.4; only a monitor, keyboard and mouse are needed.

Which memory capacity should I choose — 32 GB or the maximum 192 GB?

Start with the installed 32 GB DDR5 for typical CAD and modelling workloads; upgrade later to 192 GB if projects exceed current capacity.
