500 W Platinum Hot-Plug Power Module

This HP Flex Slot power supply delivers up to 500 W of output with 94 percent efficiency at 80 Plus Platinum level. It is designed for data-centre servers that require redundant, hot-swappable power in a compact form factor.

ProLiant DL300 Gen9 compatibility and slot space

The unit fits the Flex Slot bay used across the ProLiant DL300 Gen9 family and is 25 percent smaller than the previous generation, freeing space for additional server options. Verify that your chassis accepts Flex Slot modules and that the total load stays within the 500 W rating.

Efficiency, noise and thermal behaviour

At 94 percent efficiency the module wastes less power as heat, helping to lower overall rack temperatures. Hot-plug capability allows replacement without shutting down the server, reducing service interruption while maintaining stable power delivery.

Perguntas sobre este artigo

Does the kit include the power cable or must it be purchased separately?

The kit is a hot-pluggable 500 W Flex Slot power module; the AC power cable is not included and must be sourced to match your local 100-240 V supply.

Which part numbers correspond to this 500 W Platinum unit versus the higher-wattage options?

This unit carries retail part 720478-B21 and option parts 723594-001, 754377-001 and 723595-101; the 1400 W Platinum Plus supply uses a different option number.

What does the 94 % efficiency rating deliver in a ProLiant DL300 Gen9 server?

At 94 % typical efficiency the 500 W module draws less AC power for the same DC load, cutting waste heat and lowering operating cost in the supported DL300 Gen9 family.
