275 W replacement for Optiplex SFF

This 275 W server power supply is built for Dell Optiplex 740, 745 and 755 small form factor systems. It fits the original chassis and connectors so the machine powers on without adapter cables or case modifications. Buyers restoring or maintaining these legacy desktops get a direct-fit unit that matches the factory specification.

Capacity and headroom

The 275 W rating covers the CPU, integrated graphics and a typical complement of drives and expansion cards that shipped with these models. It will not support discrete graphics cards that require supplementary power connectors or sustained loads above the rated output. Systems upgraded with high-wattage processors or multiple spinning drives may exceed the available headroom.
