HPE 460 W Common Slot Power Supply

The HPE 656362-B21 is a 460 W Common Slot Platinum Plus hot-plug power supply kit designed for Hewlett Packard Enterprise server and storage platforms. It shares a common electrical and physical form factor that enables tool-less, hot-swap installation in compatible bays. The unit delivers up to 94 % efficiency to reduce energy waste and lower operating costs in data-centre environments. It helps avoid trapped power capacity by letting administrators right-size each deployment.

Suited for HPE CS bay servers needing 460 W

This supply fits administrators running HPE ProLiant or storage systems equipped with Common Slot bays that require a 460 W Platinum Plus unit. It supports hot replacement without downtime and integrates with HP Power Discovery Services for improved power management. Buyers whose hardware lacks a Common Slot interface or who need a higher or lower wattage rating should look at other form factors or capacities. The kit does not serve non-HPE chassis or proprietary power designs.

460 W maximum output decides fit

The single specification that determines compatibility is the 460 W maximum power rating matched to the Common Slot Platinum Plus form factor. Only systems that list this exact wattage and slot type in their qualified options list will accept the unit. Efficiency reaches 94 % under typical loads, contributing to reduced data-centre power draw. Verify the server or storage product quick-specs before purchase to confirm the correct power supply kit.
