305W Replacement for Dell Optiplex MT

This 305 watt power supply replaces the original unit in Dell Optiplex 360, 380, 580, 745, 755, 760, 780 and 960 mini-tower systems. It matches the L305P-01 form factor and connects to the existing motherboard and drive cables. The unit accepts 100 to 240 volt input at 4.7 amps for worldwide use. Builders restoring or repairing these specific chassis will find a direct mechanical and electrical fit.

Input range and output ceiling

The adapter operates on 100 to 240 volt mains at 50 to 60 hertz without a voltage selector switch. Maximum continuous output is capped at 305 watts, so the unit cannot support upgrades that push total system draw beyond that limit. High-wattage graphics cards or additional drive arrays may exceed the available headroom. The fixed limit also means the supply cannot be repurposed for platforms requiring higher peak power.

Mini-tower mounting and connector layout

The PSU uses the standard Dell mini-tower bracket and screw pattern, aligning with the original four mounting points at the rear of the case. Its wire harness carries the proprietary mainboard connector and peripheral plugs found on the listed Optiplex models. Cable lengths are tailored to the MT chassis depth, so routing reaches the motherboard and drive bays without strain. The design does not fit small-form-factor or ultra-small-form-factor variants, which use a shorter housing and different connector keying.
