280W replacement for Dell OptiPlex XE SFF

This 280 watt ATX power supply is built as a direct replacement for the Dell OptiPlex XE small form factor desktop. It matches the DPS-280MB A A and D499R part numbers used in those systems. The unit is supplied new and has been tested for working operation before shipment. It suits owners who need a like-for-like unit to restore power to a compatible chassis.

Limited to proprietary Dell SFF pin-out

The supply uses a Dell-specific connector layout and physical size that fits only the OptiPlex XE SFF and the listed server models such as the Y738P and L280E-01. It will not connect to standard ATX motherboards or fit full-size cases without an adapter. Builders planning a custom build or a different Dell model should verify the exact part number before ordering.
