Built for engineering workloads

This Adamant Custom workstation pairs a 16-core Ryzen 9 9950X3D with an NVIDIA RTX A4000 16GB professional graphics card. It runs Windows 11 Pro on 128GB of DDR5 memory and stores active projects on a 4TB NVMe Samsung 990 PRO drive. A 10TB hard drive adds bulk capacity for archives and datasets.

Suits GPU-accelerated CAD and simulation

The certified RTX A4000 driver stack and 16GB VRAM make this system a match for SolidWorks, CAM toolpaths and CAE solvers that rely on professional GPU APIs. Buyers who need more VRAM for massive assemblies or who require multiple professional GPUs should look at a different configuration.

Deciding spec: RTX A4000 16GB VRAM

The 16GB frame buffer on the professional GPU determines whether large models stay in video memory or spill to system RAM. If your typical scene fits inside that 16GB limit the workstation will deliver the certified stability the A4000 is validated for.

Questions about this item

Does the Samsung 990 PRO NVMe drive run at PCIe 4.0 speeds on the X870 motherboard?

Yes, the 4 TB Samsung 990 PRO is a PCIe 4.0 x4 drive and the Gigabyte X870 AORUS board provides four M.2 connectors that support that standard.

Will the 360 mm AIO cooler fit in the mid-tower case with the front 140 mm fans installed?

The case dimensions are 447 x 215 x 469 mm and it ships with two 140 mm front fans; the 360 mm radiator mounts in the roof, leaving the front fans in place.

How is the 128 GB DDR5 memory installed across the four slots, and what mistake should I avoid?

The board has four DDR5 slots; the 128 GB kit fills all four, so populate every slot — do not leave gaps or mix capacities.
