16-Core Workstation for Engineering Modelling

This Adamant Custom desktop pairs a 16-core AMD Ryzen 9 9950X3D with an Nvidia RTX A4000 16GB GPU, 128GB DDR5 memory and a 4TB NVMe SSD. It targets engineers running SolidWorks, CAD, CAM or CAE workloads that demand high single-thread frequency and certified professional graphics drivers. The system ships with Windows 11 Pro on a mid-tower chassis.

PCIe 4.0 Storage and USB 40Gbps Rear I/O

The Samsung 990 PRO SSD operates over a PCIe 4.0x4 link with sequential reads up to 7450 MB/sec and writes up to 6900 MB/sec. Rear connectivity includes two USB4 ports at 40Gbps, three USB 10Gbps ports, four USB 5Gbps ports and one USB 2.0 port. Internal expansion uses four M.2 connectors and two SATA 6Gb/s headers on the TUF X870-PLUS motherboard.

Verify 360mm Radiator Clearance

The 360mm liquid cooler requires a case that can mount a 360mm radiator; the supplied Corsair 4000D chassis supports this. The Thermaltake Smart 850W 80 PLUS Bronze PSU delivers 850 watts with Japanese main capacitors and protections for over-voltage, under-voltage, over-power and short-circuit. Buyers adding further drives or cards should confirm the remaining power headroom.
