255W ATX replacement for Dell OptiPlex SFF

This 255 watt ATX power supply is built as a direct replacement for the original L255ES-00, AC255AS-00 and AC255ES-00 units found in Dell OptiPlex 3020, 7020 and 9020 small form factor desktops. It is intended for system builders and IT technicians who need a tested, working unit to restore power to these specific chassis.

Restores factory power delivery in supported models

The unit replaces a failed or ageing original supply in the listed OptiPlex SFF systems, returning the machine to its rated 255 watt capacity. The jump is worth it when the existing power supply has failed, shows voltage instability or prevents the system from posting. It is not suitable for larger tower chassis, higher wattage configurations or proprietary form factors outside the named models.
