Precision 3650 workstation for professional

The Dell Precision 3650 is a mid-tower workstation built for demanding professional tasks such as CAD design, 3D modelling, engineering analysis and content creation. It runs on an Intel Core i7-11700K processor with eight cores operating at 3.6 GHz and a 5.0 GHz turbo frequency. The system includes 128 GB of DDR4 3200 memory configured as four 32 GB modules and a 4 TB PCIe NVMe solid-state drive. Integrated Intel UHD Graphics 630 provides dual DisplayPort output for multi-monitor setups.

460 W 80PLUS Gold power supply

A Dell 460 W power supply with 80PLUS Gold certification delivers efficient power to the components. The integrated Intel UHD Graphics 630 handles display duties without a discrete graphics card, reducing overall system power draw and acoustic output during typical office and workstation workloads. Integrated Intel I219-LM Gigabit Ethernet and Realtek ALC3246 high-definition audio are also onboard. Windows 11 Pro 64-bit is pre-installed with digital activation.

Four memory slots filled at maximum capacity

The 128 GB DDR4 3200 configuration occupies all four available memory slots at the platform's maximum supported capacity, leaving no room for further memory expansion without replacing existing modules. The 4 TB NVMe drive provides substantial high-speed storage for large project files and applications. Buyers who need ECC memory error correction or discrete GPU acceleration for rendering and compute tasks should verify compatibility before purchase. No monitor is included.

Questions about this item

How do I install the 128GB DDR4 3200 memory kit into the four DIMM slots?

Power off the workstation, open the mid-tower side panel, align each 32GB unbuffered module with the keyed DDR4 slot and press firmly until the retention clips click; all four slots must be populated to reach the 128GB maximum.

When will the 460W 80PLUS Gold power supply likely need replacement?

Under typical office loads the 460W unit can run for several years; plan to swap it if you add a discrete GPU or notice unexpected shutdowns during sustained heavy workloads.

What thermal limit appears first when the i7-11700K runs at 5.0GHz turbo for long periods?

The processor will hit its thermal throttle point before the 460W supply reaches its continuous output ceiling, so sustained turbo clocks depend on the stock cooler and case airflow.
