24-Core Ultra 9 Workstation

The Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K processor with 128GB of DDR5 memory and an Nvidia RTX PRO 4000 Blackwell graphics card. A 4TB NVMe drive and a 10TB hard drive provide fast primary storage and deep archival capacity. Liquid cooling and an 850W power supply support sustained workloads in a mid-tower chassis.

Suits CAD and simulation users.

Engineers running SolidWorks, CAM or CAE packages gain 24GB of GPU memory and 128GB of system RAM for large assemblies and simulation data. The four memory slots allow expansion to 192GB when datasets grow. Builders who need a second graphics card or more than four M.2 drives should look at a larger platform.

128GB RAM and 4TB NVMe headroom

The 128GB DDR5 kit handles complex models and multi-application workflows without paging, with headroom to 192GB via the two free slots. The 4TB Samsung 990 PRO delivers up to 7450 MB/s reads for rapid project loading. The 10TB hard drive adds bulk storage for archives, while the 24GB GPU frame buffer supports large visualisation scenes.

Questions about this item

Do I need to buy a separate display to use the RTX PRO 4000 Blackwell 24GB GPU?

Yes, the workstation has no built-in screen; connect a monitor to the GPU DisplayPort or HDMI outputs.

Can I keep my SATA 6Gb/s hard drives when moving to the Z890 TUF motherboard?

The board provides four SATA 6Gb/s ports so existing SATA drives plug in directly.

How can I verify the Samsung 990 PRO 4TB NVMe SSD is running at PCIe 4.0x4 speed after setup?

Open Task Manager Performance tab or run CrystalDiskMark; sequential reads near 7450 MB/s and writes near 6900 MB/s confirm full PCIe 4.0x4 operation.
