Compatible 400W server power supply

This 400W unit replaces the DPS-400AB-5 in H-P SE316M1 and DL320G6 servers. It suits administrators who need a direct-fit replacement to restore power redundancy or fix a failed module. Builders working with other chassis or custom enclosures should verify pin-out and form factor before ordering. The part numbers 532478-001 and 509008-001 confirm the correct match for these specific models.

Thermals and power draw

Rated at 400W, the supply delivers the wattage specified for the supported server platforms. Normal operation relies on the host system’s airflow design to manage thermals and acoustic output. No independent fan curve, efficiency rating or noise figure is provided in the data, so exact thermal behaviour under load cannot be stated. Installers should ensure the server’s cooling path remains unobstructed.

Included hardware

The unit ships as the power supply module only. Administrators must reuse existing brackets and connectors from the original installation. Buyers who require extra cabling or a rail kit for a different chassis will need to source those separately.

Questions about this item

How do I install the DPS-400AB-5 into an HP DL320 G6 and what step is often missed?

Slide the unit into the chassis until the latch clicks, then secure the retention screw; the step often missed is tightening that screw after the latch engages.

What maintenance or replacement will the DPS-400AB-5 need over time?

The internal fan bearings will eventually wear; plan to replace the entire supply or have the fan serviced when noise or airflow drops.

What limit appears first when the DPS-400AB-5 runs at full 400 W continuously?

Thermal protection triggers first; sustained 400 W load raises internal temperature until the over-temperature circuit shuts the unit down.
