What this power supply is

The HP 503296-B21 is a 460W 12V hot-plug AC server power supply kit designed for HP ProLiant DL servers. It delivers 460 W of output power and carries 80 Plus and ENERGY STAR certifications for energy-efficient operation in compatible rack systems.

Who this suits and who it does not

This unit fits administrators maintaining HP ProLiant DL360 G6, G7, DL370 G6, DL380 G6 and DL380 G7 servers that require a 460W 12V hot-plug module. It does not suit builds needing higher wattage, different voltage rails, or non-HP chassis that lack the matching hot-plug backplane.

The specification that decides fit

The 460 W output rating and 12V hot-plug form factor determine whether this supply matches the server’s power budget and bay layout. Verify the exact ProLiant model and existing supply label before ordering to confirm compatibility.

Questions about this item

At what load does the 460 W rating become the limiting factor during continuous operation?

The 460 W output is the sustained limit; the unit delivers up to 460 W continuously while the server draws power.

What noise and heat levels should I expect when the supply runs all day in a ProLiant DL380 G7?

The 80 Plus certified unit runs efficiently, reducing waste heat; the server chassis fans control airflow and acoustic output.

Which server chassis and backplane must I already have for this hot-plug supply to install and function?

It fits HP ProLiant DL360 G6, G7, DL370 G6, DL380 G6 and G7 models with a matching hot-plug power bay.
