Exact OEM Replacement

This 180W power adapter is a direct replacement for the HP PA-1181-6HY and D16-180P3A units. It matches the original 95×72×165mm dimensions and mounting hole layout for the HP ProDesk 280 Pro G3 MT chassis. No case modification is required for installation. The unit includes a dedicated 4+4Pin CPU power cable and the proprietary 7Pin mainboard harness with factory wiring lengths.

Suitable For & Not Suitable For

This unit suits repair shops, corporate IT maintenance teams, and individuals replacing a failed power supply in the specific HP ProDesk 280 Pro G3 MT desktop. It supports standard office, document, and light business workloads with 80PLUS Bronze efficiency. Builders working on any other chassis, form factor, or motherboard pinout should look elsewhere, as the proprietary 7Pin connector and physical dimensions are unique to this model.

Deciding Specification

The proprietary 7Pin mainboard connector combined with the fixed 95×72×165mm housing is the single specification that determines compatibility. Only the HP ProDesk 280 Pro G3 MT uses this exact connector pinout and chassis mounting pattern. If the target system does not require this specific 7Pin harness and physical footprint, this adapter will not function.

Questions about this item

Which version of this 180W adapter matches my HP ProDesk 280 Pro G3 MT?

The unit is built to the original PA-1181-6HY and D16-180P3A part numbers, with identical 95×72×165 mm dimensions and mounting holes for a direct swap.

What does the 180W rating mean for daily office use?

It delivers stable continuous output for document editing, web browsing and light business workloads while the 80PLUS Bronze circuit keeps idle power loss low.

How does the 4+4Pin CPU connector work with the proprietary 7Pin mainboard harness?

Both cables follow the factory pin-out and length, so the PSU plugs straight into the motherboard without adapters or rewiring.
