Compatible Dell SFF models

This 180 W server power supply replaces the original unit in Dell OptiPlex 3040, 5040 and 7040 small-form-factor desktops as well as Inspiron 3650 and 3656 SFF systems. It matches the listed part numbers including 9XD51, RWMNY, 5XV5K, WYX72, HGRMH and J1J77.

Who this suits and who should look elsewhere

It suits owners of the compatible Dell SFF chassis who need a direct 180 W replacement with the same connector layout and input range. Builders using a different form factor, a higher-wattage requirement or a non-Dell platform should look at other units.

Deciding specification — 180 W maximum output

The 180 W rating is the single figure that determines whether this supply can meet the power budget of the target system. If the build demands more than 180 W, this unit will not be sufficient.
