Professional CAD Workstation

The Lenovo ThinkStation P620 is a tower workstation built for engineering, drafting, 3D modeling and visualization workloads. It runs Windows 11 Pro and uses an AMD Ryzen Threadripper PRO 3945WX processor with 12 cores and 24 threads at 4.0 GHz base and 4.30 GHz boost. The system includes 192GB of DDR4 ECC memory across 8 slots and an NVIDIA Quadro M4000 graphics card for professional graphics tasks.

Build Integration

The chassis provides 2 built-in PCIe Gen 4 NVMe M.2 slots and supports multiple PCIe Gen 4 expansion cards for additional GPU, networking and NVMe storage scaling. A 1000W power supply delivers headroom for demanding components and future upgrades. Storage ships as a 2TB NVMe SSD and a 12TB 7200rpm HDD, combining fast boot and application response with high-capacity project storage.

Thermals and Power

The 1000W unit powers the 12-core Threadripper PRO CPU, Quadro M4000 GPU, 192GB memory population and dual-drive storage array under sustained professional loads. Tower airflow manages heat from the processor, graphics card and storage during extended rendering or simulation sessions. Windows 11 Pro enables modern power management features for efficient operation across variable workloads.

Questions about this item

How does the 1000W power supply cope with sustained full-load power draw?

The 1000W unit feeds the Threadripper PRO 3945WX, 192GB DDR4, M4000 and both drives, leaving headroom for PCIe Gen 4 add-in cards and extra NVMe storage under continuous load.

What are the typical noise and heat levels when the workstation runs all day?

The tower chassis and 1000W supply are designed for workstation-class thermal management, so fan noise stays low while the 12-core CPU at 4.0 GHz base and M4000 GPU dissipate heat during extended sessions.

Which display cables or adapters must I already own for the M4000 graphics card?

The Quadro M4000 provides DisplayPort outputs, so have DisplayPort cables or active DisplayPort-to-HDMI/DVI adapters ready for your monitors.
