Dell M8811 220W Adapter for OptiPlex USFF

This Dell M8811 AC adapter delivers 220 watts of power for OptiPlex SX280 and GX620 ultra-small-form-factor desktops. It is a direct replacement unit built to the original manufacturer specification. The power cable is not included and must be sourced separately. Buyers needing a higher-wattage supply for upgraded components cannot use this model.

Installation notes and common issues

The adapter plugs into the dedicated port on the USFF chassis and requires no tools to seat. Ensure the connector is fully engaged or the system will not receive power. A missing or faulty power cable is the most frequent reason the unit appears dead on arrival. Verify the cable and wall outlet before assuming the adapter has failed.
