Professional workstation for CAD and engineering

The Dell Precision 3650 mid-tower targets engineers, designers and analysts who need reliable CPU and GPU performance for 3D modelling, simulation and financial workloads. An 8-core Intel Core i7-11700K running at 3.6 GHz with 5.0 GHz turbo drives multitasking across professional applications. Windows 11 Pro provides the operating environment.

Quadro P620 adds four mini-DisplayPort 1.4 outputs

The Nvidia Quadro P620 2 GB GDDR5 card with a 128-bit bus drives up to four displays via mDP 1.4, enabling multi-monitor setups for CAD viewport work. Certified drivers improve stability in ISV applications compared with consumer graphics. The 460 W 80PLUS Gold power supply delivers efficient power to the CPU and GPU under sustained load.

Mid-tower chassis simplifies component access

Tool-less side-panel removal exposes the LGA 1200 socket, four DDR4 DIMM slots already populated with 128 GB at 3200 MHz, and the M.2 NVMe SSD bay. Builders must verify cooler clearance for the 11700K before upgrading the air cooler. The single 2 TB NVMe drive leaves no free M.2 slot for a second boot drive without an adapter.

Questions about this item

How much DDR4 memory can I add later?

The board already holds the maximum 128 GB DDR4 3200, so no further modules can be installed.

What limits sustained CPU performance?

The 460 W 80PLUS Gold power supply caps total system draw under prolonged load.

How loud and hot does it get running all day?

The 460 W Gold-rated supply and mid-tower chassis keep thermals and fan noise moderate during extended workloads.
