DELL Precision 3650 Mid-Tower i7-11700K 16GB 2TB NVMe Quadro P620 Windows 11 Pro

Entry-level professional workstation

The Dell Precision 3650 mid-tower workstation is built for engineers, designers and analysts who need dependable performance for CAD, 3D modelling and content-creation workloads. An 8-core Intel Core i7-11700K processor runs at 3.6 GHz with a 5.0 GHz turbo boost, while 16 GB of DDR4-3200 memory and a 2 TB NVMe SSD provide fast access to large project files. The Nvidia Quadro P620 with 2 GB GDDR5 drives up to four displays via mini DisplayPort 1.4.

Check motherboard memory slots and PSU connectors

Before ordering, verify that your existing DDR4 modules match the 3200 MHz speed and unbuffered specification if you plan to expand toward the 128 GB maximum capacity. The board uses an LGA 1200 socket, so any CPU upgrade must remain within that platform. Confirm that the 460 W 80PLUS Gold power supply includes the necessary PCIe power connectors for the graphics card you intend to keep or add.

Thermals noise and power draw

The 460 W Gold-rated supply delivers efficient power conversion for typical workstation loads. Under normal CAD or modelling tasks the CPU and Quadro P620 run within their thermal envelopes, keeping fan speeds moderate and acoustic output low in a standard office environment. Heavy sustained rendering will raise component temperatures and fan RPM, but the mid-tower chassis provides adequate airflow for the factory configuration.
