Professional workstation for CAD and 3D rendering

The Lenovo ThinkStation P620 tower is configured for CAD, 3D modelling, rendering, engineering and creative production. An AMD Ryzen Threadripper PRO 3945WX processor with 12 cores and 24 threads runs at a 4.0 GHz base frequency and 4.30 GHz boost. 48GB of installed DDR4 ECC memory supports large project files and smooth multitasking. Windows 11 Pro provides modern security and remote desktop features.

NVIDIA RTX A2000 graphics and mixed storage

The NVIDIA RTX A2000 with 12GB accelerates CAD, 3D visualisation, rendering and GPU-enabled creative applications. A 1TB NVMe M.2 SSD delivers responsive solid-state performance for the operating system and active projects. A 2TB HDD spinning at 7200rpm adds capacity for applications, media and backups. Two built-in PCIe Gen 4 NVMe M.2 slots allow further storage scaling.

Tower chassis with 1000W power supply

The tower form factor houses a 1000W power supply that supports demanding components, add-in cards and future configuration flexibility. Multiple PCIe Gen 4 expansion slots enable additional GPU, networking and NVMe storage upgrades. Eight DIMM slots support up to 1TB of DDR4 ECC RDIMM memory. Stock photos may differ from the exact unit configuration.

Questions about this item

How much ECC DDR4 RAM can I add to the eight DIMM slots later?

The board supports up to 1 TB of DDR4 ECC RDIMM across its eight slots, so you can expand well beyond the 48 GB installed.

Which component hits its limit first during long rendering sessions on the RTX A2000?

The RTX A2000 12 GB frame buffer fills before the 12-core Threadripper PRO 3945WX or the 1000 W supply become bottlenecks.

What noise and heat should I expect from the 1000 W supply and RTX A2000 running all day?

The 1000 W unit and RTX A2000 are cooled by the tower's thermal design; under sustained load the fans ramp up but stay within workstation-class acoustic targets.
