Ryzen 9 9900X3D workstation desktop

This business desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with 128 GB of DDR5 memory and an NVIDIA RTX PRO 4500 Blackwell graphics card. Liquid cooling and an 850 W power supply support sustained workloads. Windows 11 Pro is pre-installed. The system is built for professional CAD, CAM and CAE modelling.

Suits GPU-accelerated modelling.

Engineers running SolidWorks or similar GPU-accelerated applications will benefit from the 32 GB video memory and PCI Express x16 link. Buyers who need multiple graphics cards for render farms should look elsewhere. The single GPU configuration also limits virtual desktop density for shared workstations. Wi-Fi 7 and 2.5G Ethernet cover modern connectivity.

32 GB RTX PRO 4500 Blackwell decides fit

The NVIDIA RTX PRO 4500 Blackwell provides 32 GB of video memory on a PCI Express x16 interface. This capacity determines whether large assemblies and simulation datasets fit in GPU memory. If your workflow demands more video memory, this card will not suffice. All other specifications scale around this graphics subsystem.

Questions about this item

Will the PRIME X870-P motherboard's AM5 socket let me reuse my existing DDR5 memory kits alongside the installed 128GB?

The board supports up to 192GB total, so you can add compatible DDR5 modules to the four slots, but the 128GB already installed uses high-performance sticks that set the speed baseline.

How can I verify the RTX PRO 4500 Blackwell is running at full PCIe x16 bandwidth after assembly?

In Windows Device Manager check the GPU link width — it should show x16 Gen 4, and NVIDIA's control panel will report 32GB VRAM and driver version matching the Blackwell architecture.

Which storage drives come pre-fitted and what extra bays remain for my own drives?

Two 4TB Samsung 990 PRO M.2 NVMe SSDs and one 10TB 3.5-inch HDD are installed; the case still has one free 3.5/2.5-inch bay and one dedicated 2.5-inch bay for additional SATA drives.
