Adamant Custom Ryzen 9 9900X3D 128GB 2TB NVMe 10TB HDD RTX PRO 4000 Blackwell business desktop

Workstation for CAD and modelling

This business desktop is built around a 12-core AMD Ryzen 9 9900X3D processor with 128GB of DDR5 memory and an NVIDIA RTX PRO 4000 Blackwell graphics card carrying 24GB of video memory. It targets engineers and designers who need strong single-thread speed and certified drivers for SolidWorks, CAM and CAE workloads. Buyers who require more than 192GB of system memory or multiple GPU configurations will need a different platform.

PCI Express 4.0 storage and I/O limits

The 2TB Samsung 990 PRO NVMe drive runs on a PCIe 4.0 x4 link, delivering sequential reads up to 7450 MB/s and writes up to 6900 MB/s. The motherboard provides four M.2 connectors, but only the primary slot operates at full PCIe 4.0 x4 speed; additional drives may share bandwidth with the chipset. Rear I/O includes two USB4 ports at 40Gbps, three USB 10Gbps ports and four USB 5Gbps ports, while internal headers add one USB 20Gbps connector.

Memory and storage headroom

The system ships with 128GB of DDR5 installed and the board supports a maximum of 192GB, leaving room for a modest upgrade. The 10TB hard drive adds bulk capacity for project archives, while the 2TB NVMe drive handles active data sets. Users working with extremely large assemblies or simulation datasets may find the single 2TB NVMe volume limiting and should plan for external or network-attached storage.
