Power supply for HPE ProLiant servers

The HPE 656363-B21 is a 750W Common Slot Platinum Plus hot-plug power supply designed for compatible HPE ProLiant server platforms. It delivers single-module output for installations that do not require redundant power configurations. The unit accepts 100-240V AC input at 50/60Hz for worldwide deployment.

Hot-plug Common Slot form factor

The supply uses the HPE Common Slot design measuring 1.5" x 3.4" x 7.5" and weighing 3 lbs, allowing tool-free replacement while the server remains operational. Platinum 80Plus certification confirms 94% typical efficiency, reducing heat output and operating cost in dense rack environments. The kit includes part 69061R for immediate installation.

750W single-module capacity

Maximum rated output is 750W, which determines whether this unit can support the configured processor, memory, storage and expansion cards in your specific chassis. Verify the total system power budget against this limit before purchase; configurations requiring higher wattage or N+N redundancy will need a different power supply.

Questions about this item

Does the 80 Plus Platinum rating keep efficiency at 94% across the 100-240 V input range?

The unit is certified 80 Plus Platinum and rated at 94% efficiency at 220 V AC input.

Will the 1.5 x 3.4 x 7.5 inch Common Slot form factor fit an HPE ProLiant DL360 Gen9 bay?

Yes, the Common Slot Platinum Plus design matches the DL360 and DL160 series bays listed in the compatibility data.

Can I hot-plug this 750 W supply into a live DL160 without shutting down the server?

The module is hot-plug rated; insert it firmly until the latch clicks so the power blades seat before the signal pins engage.
