HP 460W Common Slot Platinum Plus PSU

This HP 460W Common Slot Platinum Plus power supply fits HP server and storage platforms that accept the Common Slot form factor. It delivers up to 460W of output with 94 percent efficiency across a 110 to 220 V input range. Hot-plug capability allows tool-less replacement without shutting down the system. The unit is new and carries part numbers 656362-B21, 660184-001 and 643931-001.

Suits HP Common Slot bays only

It suits administrators who need a 460W platinum-efficiency module for compatible HP ProLiant or storage enclosures. It is not for builders using standard ATX, EPS or proprietary non-Common-Slot chassis. It is not for deployments that require redundant units beyond the capacity of a single 460W module. It is not for environments needing a different input voltage range or a higher wattage rating.

460W maximum power at 94 percent efficiency

The single specification that decides fit is the 460W maximum power rating combined with 94 percent efficiency. This determines whether the module can support the server configuration without exceeding its thermal and electrical budget. Verify the chassis power budget and Common Slot compatibility before purchase.
