HP 750W Common Slot Platinum

This 750-watt proprietary server power supply uses the HP Common Slot form factor for hot-plug replacement in compatible chassis. It is built for IT teams who need Platinum-rated efficiency in dense rack environments. The unit carries part numbers 593831-B21 599383-001 591556-101 for ordering accuracy.

Sustained-load behaviour

Platinum certification means the supply maintains high efficiency across the load curve rather than only at peak. In continuous operation it delivers stable 750-watt output without the efficiency drop-off seen in lower-rated units. This reduces waste heat during long compute windows.

Thermals noise and power draw

The 2.0-pound chassis fits standard Common Slot bays and relies on system airflow for cooling. Fan speed ramps with internal temperature so acoustics stay low at typical utilisation. Power draw at the wall reflects Platinum-level conversion losses under normal server workloads.

Questions about this item

How much heat and noise does the 750-Watt Common Slot Platinum supply produce under continuous load?

The unit is rated for 750 W output with Platinum efficiency, so waste heat is lower than standard supplies; actual fan noise varies with server chassis airflow and temperature sensors.

Which server chassis or backplane must I already own for this DPS-750UB B supply to connect and power on?

It uses HP's proprietary Common Slot interface, so it only fits HP ProLiant and Apollo servers designed for Common Slot power supplies.

Will this 593831-B21 supply work in an older ProLiant G6 or G7 that still uses the earlier hot-plug form factor?

No — the Common Slot form factor is physically and electrically different from the previous hot-plug design, so it cannot be installed in those generations.
