20-Core Ultra 7 Workstation

This business desktop pairs a 20-core Intel Core Ultra 7 265K processor with 32GB DDR5 memory and an Nvidia RTX PRO 2000 Blackwell graphics card. It runs Windows 11 Pro and uses liquid cooling for the CPU. The system targets SolidWorks CAD modelling and AI workloads.

Suits CAD and AI users

Engineers and designers who need certified drivers for professional 3D applications will benefit from the RTX PRO 2000 Blackwell GPU and high core count. Buyers who require ECC memory or multi-GPU rendering farms should look at a different platform.

Straightforward desktop setup

The Corsair 4000D chassis arrives assembled with the 240mm AIO cooler pre-installed, so only power, display and peripherals need connecting. The motherboard offers four M.2 slots and four SATA ports for future storage expansion.

Questions about this item

Does the Z890 motherboard require DDR5 memory for the Intel Core Ultra 7 265K to function?

Yes, the Intel Core Ultra 7 265K uses the LGA 1851 socket and the Z890-PLUS TUF motherboard only supports DDR5 memory, so DDR5 modules are mandatory for the system to boot.

Can I keep my existing SATA hard drives and connect them to the four SATA 6Gb/s ports on the Z890 motherboard?

Yes, the motherboard provides four SATA 6Gb/s ports, so any existing 2.5-inch or 3.5-inch SATA drives you own can be installed in the case's internal bays and connected directly.

After building the system, how can I verify the Samsung 990 PRO SSD is running at its advertised PCIe 4.0 x4 speeds?

In Windows 11 Pro, open Task Manager, select the Performance tab, click the 4TB NVMe drive, and confirm the link speed reads PCIe 4.0 x4; then run a sequential benchmark to see read speeds approach 7450 MB/s and write speeds near 6900 MB/s.
