Replacement PSU for Dell Optiplex MT

The Vszerda 305W NH493 unit replaces the original power supply in Dell Optiplex 360, 380, 580, 745, 755, 760, 780 and 960 Mini Tower systems. It matches the L305P-01, N305P-06 and related Dell part numbers listed for those chassis. Buyers restoring or repairing these specific models receive a direct swap component. This adapter is not for small form factor, ultra-small or proprietary non-MT Dell cases.

Tested unit with standard ATX connectors

Each power supply is tested before shipment and arrives in new condition. The housing fits the Mini Tower mounting points and supplies the motherboard, drive and peripheral connectors required by the listed Optiplex models. Universal 100-240V input at 4.7A allows operation on global mains voltages from 50 to 60Hz without a voltage selector switch. Builders needing redundant or hot-swap server supplies cannot use this unit.

305W maximum output capacity

The supply delivers up to 305W total power across its rails, matching the factory rating for the compatible Optiplex MT platforms. Systems upgraded with high-wattage discrete graphics cards or multiple additional drives may exceed this budget. Verify the combined load of your components against the 305W limit before installing.
