Dell Precision 3650 Mid-Tower Workstation

The Dell Precision 3650 is a mid-tower workstation built for professional workloads such as CAD, 3D modelling and financial analysis. It runs on an Intel Core i9-10900K 10-core processor with a 5.3 GHz turbo frequency and 128 GB DDR4 2933 MHz memory. A 2 TB PCIe NVMe SSD and Nvidia Quadro P620 2 GB GDDR5 graphics provide fast storage and certified driver support. Windows 11 Pro is pre-installed.

Suited for professional applications

This system suits engineers, designers and analysts who need ECC-capable memory architecture, ISV-certified graphics drivers and a 460 W 80PLUS Gold power supply in a mid-tower chassis. It is not for buyers who require multiple high-power GPUs, higher-wattage power delivery or rackmount form factors. The four mini-DisplayPort 1.4 outputs support multi-monitor productivity setups.

128 GB DDR4 2933 MHz maximum memory capacity

The workstation supports a maximum of 128 GB DDR4 2933 MHz across four slots, populated here as 4 x 32 GB unbuffered modules. This ceiling determines whether the platform can accommodate your dataset size or virtualisation density. No further memory expansion is possible beyond this limit.

Questions about this item

How much power does the 460 W 80PLUS Gold supply draw when the i9-10900K runs at 5.3 GHz all day?

The 460 W 80PLUS Gold unit is sized for the 10-core i9-10900K and its 128 GB DDR4 memory; under sustained load it delivers up to 460 W with Gold-rated efficiency.

Which display connectors must my monitors already have for the Quadro P620 2 GB card?

The P620 provides four Mini DisplayPort 1.4 outputs; monitors need mDP 1.4 inputs or suitable adapters.

Will my existing DDR4 2933 ECC modules work alongside the installed 4×32 GB kit?

The board has four slots filled with 128 GB total, matching the 128 GB maximum; no free slots remain for additional memory.
