Replaces failed or missing 300W unit

It directly substitutes a failed or missing 300-watt server power supply in the listed HP MT chassis. The upgrade is worth it when the original unit has failed or when a spare is needed for maintenance. No higher-wattage option is referenced in the data so this unit matches the original 300-watt rating exactly.

Verify 6-pin P2 and 4-pin connectors

Before ordering confirm that your server uses the 6-pin P2 interface plus the 4-pin connector and the small cable pin described in the specification. Check the serial number on your existing supply against 503377-001 503378-001 508153-001 508154-001 611483-001 611484-001 613764-001 or 613765-001. This product is not for systems that require a different connector layout or a higher power rating.

Questions about this item

What connectors does the PS-4321-9HA use to fit an HP 8000 MT chassis?

The PS-4321-9HA uses a 6-pin P2 interface, a 4-pin connector, and a small cable pin to match the HP 8000 MT power socket.

How is the PS-4321-9HA installed in an HP MT server, and what step is often missed?

Slide the unit into the front power bay until the latch clicks, then press the small cable pin firmly into its header; the pin is often left loose.

Which part numbers identify a correct replacement for the PS-4321-9HA later?

Match the sticker to any of 503377-001, 503378-001, 508153-001, 508154-001, 611483-001, 611484-001, 613764-001, or 613765-001.
