HP 750 W Common-Slot Power Supply

The HP 593831-B21 is a 750 W hot-plug power supply built for HP ProLiant servers. It uses the Common Slot form factor and delivers 94 % efficiency at 240 V AC input. The unit carries 80 Plus Platinum certification and supports AC 100-240 V operation. It is designed for internal mounting in compatible rack servers.

Installation notes

The supply slides into the Common Slot bay and locks with a lever, so no cables need routing inside the chassis. Because it is hot-plug capable, it can be swapped while the server remains powered if a redundant unit is present. The single fan draws air through the module; ensure the server fan wall is clean to avoid thermal throttling. Verify the chassis supports Common Slot before ordering.

Who should buy

This unit suits administrators maintaining DL380 G7, DL385 G7 or DL1000 platforms that require a 750 W Common Slot replacement or a second supply for redundancy. It is not for desktop ATX builds, non-HP racks or systems needing a different wattage or form factor. Buyers who need higher output or a different connector layout should look elsewhere.

Questions sur cet article

How can I confirm the 593831-B21 is delivering 750 W at 94 % efficiency after installation?

Monitor the server’s iLO or BIOS power telemetry; it reports real-time input and output watts so you can verify the 94 % efficiency figure under load.

What comes in the 593831-B21 kit and what must I source separately?

The kit includes the hot-plug Common Slot power supply module; cables and any required rail kits for DL380 G7, DL385 G7 or DL1000 are sold separately.

Which Common Slot version should I choose for a DL380 G7 running on 240 V AC?

Select the 750 W Platinum unit (593831-B21) — it supports 100-240 V AC input and matches the DL380 G7’s Common Slot bay.
