Built for CAD and engineering workloads

This desktop pairs a 16-core AMD Ryzen 9 9950X3D with an Nvidia RTX A4000 16GB GPU to handle SolidWorks, CAM and CAE modelling. 64GB of DDR5 memory and a 4TB NVMe SSD keep large assemblies responsive. Windows 11 Pro is installed and the system is AI ready for supported workflows.

Pre-assembled with liquid cooling and a 360mm

The CPU cooler arrives filled and mounted inside the Corsair 4000D chassis so there is no loop to build. The Thermaltake 850W 80 PLUS Bronze PSU uses a single 140mm fan and standard ATX cables. Motherboard headers follow the X870 layout; check the manual if you plan to add front-panel USB 20Gbps or extra M.2 drives.

Verify case clearance

The mid-tower measures 490 x 239 x 486 mm and offers two 3.5-inch and two 2.5-inch internal bays. Rear I/O includes two USB4 40Gbps Type-C ports, three USB 10Gbps, four USB 5Gbps and one USB 2.0 port plus Intel 2.5Gb Ethernet and Wi-Fi 7. Ensure your workspace accommodates the dimensions and that the ATX standoff pattern matches the TUF X870-PLUS board.

Questions about this item

How can I confirm the 360 mm liquid cooler is keeping the Ryzen 9 9950X3D at safe temperatures?

Open the case side panel and verify the pump and three 140 mm fans are spinning; then run a CPU stress test in Windows 11 Pro and watch core temperatures stay well below the 95 °C throttle point.

What components ship inside the Corsair 4000D case and what must I supply myself?

The box contains the complete PC — Ryzen 9 9950X3D, 64 GB DDR5, 4 TB Samsung 990 PRO NVMe, 10 TB HDD, RTX A4000 16 GB, 850 W PSU, Wi-Fi 7 and Windows 11 Pro — only a monitor, keyboard and mouse are needed separately.

Should I choose the 64 GB DDR5 configuration or plan to expand to the 192 GB maximum?

Start with the installed 64 GB DDR5; the motherboard has four slots supporting up to 192 GB total, so you can add matching modules later if workloads such as large SolidWorks assemblies demand more memory.
