Power Supply Unit HPE 775595-B21 900 W

The HPE 775595-B21 Power Supply Unit provides 900 W of AC power for ProLiant Gen9 servers in a compact form factor. Designed for server environments, this AC input module supports an input voltage range of 100–240 V and carries an 80 Plus Gold efficiency rating (up to 92%), delivering reliable, energy-efficient power for systems that require a hot-pluggable, serviceable supply.

Advantages

This 900 W HPE power supply offers high efficiency (92%) to reduce operating costs and minimize wasted energy. Its hot-pluggable AC input design enables quick replacement or deployment without powering down compatible servers. The unit’s compact dimensions and 0.4 kg weight make it suitable for tight server bay configurations where space and serviceability matter.

Suitable for

• ProLiant Gen9 servers with a compatible power bay
