1500W Common Slot Platinum Plus power supply

The HPE 684532-B21 is a 1500 watt hot-plug server power supply built to the Common Slot form factor. It carries 80 Plus Platinum certification with efficiency above 90 percent and accepts a 100 to 240 volt input range at 50 or 60 hertz. The unit operates as a single module rather than a redundant pair.

Suited for HPE Common Slot bays needing

Data-centre racks that use HPE Common Slot infrastructure can insert this supply for hot-swap maintenance without downtime. It is not for systems that lack a Common Slot chassis, for builds requiring redundant paired supplies, or for environments restricted to 100 volt circuits where the rated output cannot be delivered.

1500W maximum power at 200-240V input

The supply delivers its full 1500 watt rating only when fed from a 200 to 240 volt source, with an apparent power draw of 1681 VA. At lower input voltages the available output drops, so the 200-240V requirement is the single specification that determines whether this part matches the installation.

Questions about this item

Is the 1500W rating delivered at any input voltage or only on the higher range?

The 1500W output is specified for AC 200-240 V input; at lower voltages the available power will be reduced.

What does the 80 Plus Platinum label mean for daily server operation?

It certifies efficiency above 90% at typical loads, lowering electricity cost and reducing waste heat inside the chassis.

Does the Common Slot design limit this unit to 1500W or can higher-wattage modules fit the same bay?

Common Slot standardises the physical and electrical interface, so higher-wattage Platinum Plus modules can occupy the same bay if the server supports them.
