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.

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.
