Compatible Dell MT power supply

This 305 W unit replaces the M8805 L305P-01 PS-6311-5DF-LF NH493 in Dell 755 and 745 MT chassis. It fits the original mounting points and connector layout for direct installation.

Practical limits of proprietary Dell MT design

The supply uses Dell-specific pin-outs and mechanical keying, so it cannot power standard ATX motherboards or third-party cases. Builders needing generic ATX compatibility or higher wattage must choose a different form factor.
