Professional Workstation Configuration

The Lenovo ThinkStation P620 tower workstation is built for CAD, 3D rendering, engineering and creative production workloads. It ships with Windows 11 Pro and a 1000W power supply to support demanding components and future expansion. This system targets professionals who need certified stability for complex project files and GPU-accelerated applications.

PCIe Gen 4 Storage and Expansion Limits

Onboard storage relies on two built-in PCIe Gen 4 NVMe M.2 slots for high-speed solid-state drives. Additional GPU, networking and NVMe scaling depend on available PCIe Gen 4 expansion slots inside the chassis. Buyers who require more than two native M.2 devices must add compatible add-in cards to reach their capacity goals.

Tower Build Quality and Daily Implications

The tower form factor provides physical space for the 1000W supply, 8-channel DDR4 ECC memory architecture and full-length graphics card. Front and rear I/O placement follows workstation conventions for rack or desk deployment. Users who need a compact chassis or silent operation for noise-sensitive studios should evaluate the acoustic profile before purchase.

Questions about this item

How do I decide between the 4TB HDD and the 2TB NVMe for my primary workload?

Use the 2TB NVMe for the operating system, active projects and applications that benefit from PCIe Gen 4 speed; keep the 4TB 7200rpm HDD for archives, backups and large media libraries that do not need low latency.

What does the 4.0 GHz base clock mean when the workstation is running a sustained render job?

The 12-core Threadripper PRO 3945WX holds 4.0 GHz across all cores under load and can boost to 4.30 GHz on lighter threads, giving predictable multi-thread throughput for long renders.

Which expansion standard do the two onboard M.2 slots use and what bandwidth ceiling does it set?

Both slots are PCIe Gen 4 NVMe, so each drive can reach the full Gen 4 x4 limit without sharing bandwidth with the RTX A2000 or other add-in cards.
