Built for professional engineering workloads

This tower workstation pairs a 16-core Ryzen 9 9950X3D with an Nvidia RTX A4000 GPU and 64GB DDR5 memory. It targets CAD, CAM and CAE users who need certified driver stability and large local datasets. Windows 11 Pro ships pre-installed.

GPU VRAM capacity defines the model ceiling

The RTX A4000 provides 16GB of video memory, which limits maximum assembly size and texture resolution in SolidWorks and similar applications. Buyers who need larger GPU memory must select a different graphics card.

360 mm liquid cooler and 850W PSU anchor

The Antec P20 case supplies front 120 mm fans and dust filters on three faces. Motherboard rear I/O includes USB4 40Gbps, 2.5Gb Ethernet and Wi-Fi 7. Four M.2 slots and two 3.5-inch bays remain open for future storage expansion.

Questions about this item

What does the 16-core 4.3 GHz Ryzen 9 9950X3D deliver inside this tower?

The 16-core Ryzen 9 9950X3D runs at a 4.3 GHz base clock and can boost up to 5.70 GHz, with 128 MB of L3 cache, giving strong multi-threaded throughput for CAD, CAM and rendering workloads.

How fast can the two Samsung 990 PRO drives move data over the PCIe 4.0 x4 link?

Each 4 TB drive is rated for sequential reads up to 7450 MB/s and writes up to 6900 MB/s across the PCIe 4.0 x4 interface, so large project files load quickly.

Will the 360 mm liquid cooler and RTX A4000 fit in the Antec P20 case?

The Antec P20 mid-tower measures 469 x 220 x 490 mm and supports E-ATX boards, providing room for the 360 mm radiator and the RTX A4000 graphics card.
