YINGHUA 500W server power supply 4Pin+7Pin PA-5501-2HA

SKU CH-982M-X3XM0

Delivers 500W via 4Pin, 7Pin and 6+2Pin connectors for compatible HP desktops

  • 500 W output supports demanding server workloads
  • 100-240 V input works worldwide without a converter
  • 4-pin + 7-pin + 6+2-pin connector fits listed HP models
  • 168 mm length matches standard server chassis dimensions
  • Replaces PA-5501-2HA and compatible part numbers directly

Replacement PSU for HP G3 G4 servers

This 500W server power supply replaces the HP PA-5501-2HA unit used in 480, 280, 288, 680, 800, 600 and 400 G3 G4 systems. It accepts 100-240V input at 50 60hz and delivers up to 500W through a 4Pin + 7Pin + 6+2Pin connector arrangement. The unit measures approximately 168mm in length.

Connector layout determines fit

Installation requires matching the 4Pin + 7Pin + 6+2Pin interface to the motherboard headers found in the compatible HP models. The proprietary pin-out means the supply will not work in standard ATX chassis or servers lacking those exact headers. Builders should verify the part number PA-5501-2HA against the label on the original unit before fitting.

Steady 500W output under continuous load

The supply is rated for a maximum output power of 500W across the 100-240V input range, supporting sustained server workloads rather than brief peaks. Active cooling maintains stable voltages during extended operation in rack or tower configurations. The 168mm form factor fits the original HP bays without modification.

Questions about this item

How can I verify the 500W PSU is working after installing it in my HP 680 G4?

The unit powers on when the server starts; listen for the internal fan and confirm the front-panel LEDs show normal power status.

What comes in the box and do I need any extra cables for the 4Pin+7Pin+6+2Pin connectors?

The package includes one power supply only; the 4Pin, 7Pin and 6+2Pin cables are fixed to the unit so no separate cables are required.

My server is an HP 400 G3 — is the PA-5501-2HA the correct 500W replacement?

Yes, the PA-5501-2HA is listed as compatible with HP 400 G3 and G4 models as well as 280, 288, 480, 600, 680 and 800 series.
