Workstation-class desktop for CAD and modelling

This desktop is built around a 24-core Intel Core Ultra 9 285K processor and an Nvidia RTX PRO 4000 Blackwell graphics card with 24GB of video memory. It ships with 128GB of DDR5 system memory and a 2TB NVMe solid-state drive alongside a 10TB SATA hard drive. The combination targets engineers and designers who need high core counts and professional GPU drivers for SolidWorks, CAM and CAE workloads.

Check motherboard memory limits

The Gigabyte Z890 UD board provides four DDR5 slots and supports up to 192GB in total, so the installed 128GB kit leaves room for expansion. Four M.2 connectors are available, one of which is occupied by the Samsung 990 PRO NVMe drive. The Antec P10 FLUX case offers three internal 3.5-inch bays and three 2.5-inch mounts; the 10TB hard drive uses one 3.5-inch bay. Verify that your peripheral mix fits the rear I/O, which includes one USB4 Type-C, five USB 3.2 ports and four USB 2.0 ports.

Liquid CPU cooling and a quiet 850W supply manage

A 360mm quiet-edition all-in-one cooler handles the Core Ultra 9 285K, while the case includes three 120mm front fans, one 120mm PSU-shroud fan and a 120mm rear fan. Sound-dampening panels line the chassis. The Thermaltake Smart 850W 80 PLUS Bronze unit uses a 140mm low-noise fan and Japanese main capacitors. In typical workstation use the system runs cool and quiet, with the GPU’s professional drivers optimised for sustained compute loads.

Questions about this item

What comes in the box and what must I buy separately?

The system ships fully assembled with the Intel Core Ultra 9 285K, 128GB DDR5, 2TB NVMe SSD, 10TB SATA HDD, Nvidia RTX PRO 4000 Blackwell 24GB GPU, 850W 80 PLUS Bronze PSU, liquid CPU cooler, Windows 11 Pro, Wi-Fi 6E and Bluetooth5.3. Only a monitor, keyboard and mouse are needed separately.

Which memory capacity should I choose for this workstation?

The board has four DDR5 slots and supports up to 192GB. The 128GB kit fills all slots with high-performance modules, leaving no free slots for future expansion; choose 128GB now if you need maximum capacity immediately, otherwise a smaller kit leaves room to add more later.

What does the 24GB GPU memory mean for real workloads?

The RTX PRO 4000 Blackwell provides 24GB of video memory, allowing large SolidWorks assemblies, high-resolution textures and multi-GPU compute tasks to stay on the card without swapping to system RAM, which keeps frame rates stable and render times predictable.
