A 12-core workstation with 32GB DDR5, 4TB NVMe SSD, 10TB HDD and an RTX PRO 5000 Blackwell 48GB GPU for SolidWorks modelling and simulation
This business desktop is built for engineers and designers who run SolidWorks, CAD, CAM and CAE modelling workloads. It pairs a 12-core Ryzen 9 9900X3D processor with an NVIDIA RTX PRO 5000 Blackwell graphics card carrying 48GB of memory. The system ships with Windows 11 Pro 64-bit and 32GB of DDR5 RAM.
The jump is worth it when your current machine bottlenecks on large assemblies, simulation solve times or multi-tasking across several resource-heavy applications. The 4TB NVMe SSD delivers read speeds up to 7450 MB/sec and write speeds up to 6900 MB/sec for rapid project loading. A 10TB HDD with 256MB cache adds high-capacity secondary storage for archives and datasets.
The GPU connects through a PCI Express x16 slot, so total graphics bandwidth is capped by that interface generation. Network traffic is limited to 2.5G Ethernet unless a faster adapter is added internally. The motherboard provides USB4 at 40Gbps, USB 20Gbps, USB 10Gbps and USB 5Gbps ports for peripherals, while Wi-Fi 7 handles wireless connectivity. Maximum system memory supported is 192GB.

The Corsair 4000D chassis measures 490 x 239 x 486 mm and the factory build uses a 240 mm AIO cooler mounted in the front, leaving the four DDR5 slots on the TUF X870-PLUS motherboard fully accessible.
The 850 W Thermaltake Smart PSU supplies the GPU through its native 12VHPWR cable; seat the connector until it clicks and verify the card is secured by the case retention bracket.
The board has four DDR5 slots; with 32 GB installed you can populate the remaining two slots up to the 192 GB maximum supported by the Ryzen 9 9900X3D.
