Dell Optiplex SFF power supply

This genuine Dell 180 watt unit is built for Optiplex 3040 and 5040 Small Form Factor desktops. It replaces a failed or missing original supply with the exact connector layout those chassis expect. The part number H180ES-00 matches Dell reference J1J77.

Fits Optiplex 3040 and 5040 SFF only

Owners of other Dell SFF models or full-size towers cannot use this supply because the mounting bracket and cable lengths differ. Builders assembling a custom case or upgrading to a higher-wattage GPU should look at a standard ATX unit instead.

180 watt output with 4 pin ATX and 8 pin EPS

The unit delivers 180 watts through one 4 pin ATX +12 V connector and one 8 pin EPS +12 V connector. Verify that your motherboard requires both connectors before ordering.
