Compatible Dell Optiplex models

This 180W ATX power supply is built for Dell Optiplex 3040, 5040 and 7040 desktops using the 8-pin connector. It suits IT teams refreshing office fleets or home users restoring a familiar small-form-factor chassis with a brand-new unit.

Replaces original HU180ES-00 and HK280-87PP units

The module swaps directly for Dell part numbers HU180ES-00, HK280-87PP and J1J77 when the original supply has failed or efficiency has dropped. The jump is worthwhile if the system exhibits random shutdowns, coil whine or loud fan noise under light loads.

Check chassis clearance and 8-pin motherboard header

Verify the case accepts a standard ATX-profile PSU and that the motherboard presents the proprietary 8-pin power header used on these Optiplex models. Confirm the unit’s physical dimensions match the bay before ordering.

Questions about this item

What form factor and connector does this PSU use for the Dell Optiplex 3040, 5040, and 7040?

This unit is an ATX-type supply with an 8-pin connector built for the Optiplex 3040, 5040, and 7040 chassis.

How do I install it, and which step is often missed?

Remove the old PSU, slide this unit into the bay, secure the mounting screws, then firmly seat the 8-pin motherboard plug — the step most often missed is fully latching that 8-pin connector.

What maintenance will the fan and dust filters need over time?

The Zero RPM fan mode stops the fan at low loads, reducing dust intake; clean the intake vents with compressed air every few months and the fan will only spin up when thermal load requires it.
