DELL M619f 235 W power supply for Optiplex 360 380

Dell M619f 235 W PSU for Optiplex 360 and 380

This genuine Dell power supply delivers 235 watts to Optiplex 360 and 380 desktops. It replaces the original M619f unit when the factory supply fails or an upgrade demands a direct swap. The part fits the proprietary chassis and connector layout without adapters. Builders working on other Optiplex models or custom cases cannot use this supply.

Sustained load behaviour

The 235 watt rating supports continuous operation at the system's designed power envelope. Voltage rails remain stable during extended workloads typical of office applications. The unit lacks the headroom required for discrete graphics cards or high-wattage processors. Thermal performance matches the original cooling profile inside the Optiplex 360 and 380 enclosures.
