Lenovo ThinkStation P620 Threadripper 3945WX 4.0GHz 32GB 2TB NVMe 12TB HDD RTX A2000 1000W W11 Pro

Professional Workstation Tower

The Lenovo ThinkStation P620 is a tower workstation built for CAD, 3D modeling, rendering and engineering workloads. It ships with an AMD Ryzen Threadripper PRO 3945WX processor running at 4.0 GHz base frequency with 12 cores and 24 threads. Thirty-two gigabytes of DDR4 ECC memory are installed across eight DIMM slots, leaving room for expansion up to 1 TB. Windows 11 Pro provides the operating environment.

Storage Interface and Expansion Limits

The system includes two built-in PCIe Gen 4 NVMe M.2 slots for high-speed solid-state drives. A 2 TB NVMe drive occupies one slot, while a 12 TB 7200 rpm hard drive adds bulk capacity. Additional PCIe Gen 4 expansion cards can add further GPU, networking or NVMe storage, but the total number of lanes and slots is fixed by the platform. Buyers who need more than two native M.2 devices must add a compatible add-in card.

Build Quality and Daily Connectivity

The 1000 W power supply supports the installed RTX A2000 graphics card and leaves headroom for future add-in cards or storage upgrades. Tower form factor allows tool-less access to drive bays, memory slots and expansion bays for routine maintenance. Front and rear I/O ports are positioned for permanent desk placement rather than frequent transport. Buyers who need a compact or mobile chassis should consider a different form factor.
