Lenovo ThinkStation P620 Threadripper 3945WX 4.0GHz 48GB 4TB HDD RTX A2000 12GB hard drive adapter

Professional CAD Workstation

The Lenovo ThinkStation P620 tower is built for CAD, 3D modelling, rendering and engineering workflows. An AMD Ryzen Threadripper PRO 3945WX with 12 cores and 24 threads runs at a 4.0 GHz base frequency up to 4.30 GHz boost. Installed 48 GB DDR4 ECC memory across 8 slots handles large project files and virtual machines. Professional NVIDIA RTX A2000 graphics with 12 GB accelerate GPU-enabled creative applications.

1000W Power Thermal Headroom

A 1000 W power supply delivers stable current for the Threadripper processor, RTX A2000 card and storage array under sustained loads. The tower chassis provides airflow paths for the CPU, GPU and dual-drive storage configuration. Windows 11 Pro manages modern power states and remote desktop features for professional environments. The system supports PCIe Gen 4 expansion cards for additional GPU, networking and NVMe scaling.

Dual-Drive Storage Flexibility

One 2 TB NVMe M.2 SSD provides responsive boot and application performance. One 4 TB HDD at 7200 rpm adds capacity for project files, media libraries and backups. Two built-in PCIe Gen 4 NVMe M.2 slots allow further high-speed storage upgrades without add-in cards. Eight total DIMM slots support up to 1 TB maximum memory for future expansion needs.
