Workstation for CAD and CAE modelling

This desktop is built around a 12-core AMD Ryzen 9 9900X3D processor and an NVIDIA RTX PRO 4000 Blackwell graphics card with 24GB memory. It targets engineers and designers who run SolidWorks, CAM or CAE workloads that demand high single-thread frequency and certified professional drivers. The system ships with Windows 11 Pro and 128GB of DDR5 memory.

Sustained compute with liquid cooling

A 240mm liquid cooler keeps the CPU near its 5.50 GHz boost during long simulation or rendering jobs rather than throttling after a short burst. The 4TB Samsung 990 PRO NVMe drive delivers sequential reads up to 7450 MB/s and writes up to 6900 MB/s, feeding large assemblies without stalling. The 10TB hard drive adds 256MB cache for bulk project archives.

Quiet 850W power and 2.5G Ethernet

The Thermaltake 850W 80 PLUS Bronze supply uses a 140mm fan rated for low noise and Japanese main capacitors for stable delivery under load. Intel 2.5Gb Ethernet and Wi-Fi 7 provide fast wired and wireless connectivity for collaborative workflows. The Corsair 4000D case offers internal bays for future storage expansion.
