The HPE P44712-B21 is an 1800W–2200W Flex Slot Titanium hot-plug power supply kit for supported HPE servers and storage systems. It accepts 200–240 VAC and is specified for up to 96% efficiency, with 80 Plus Titanium certification.
Its HPE Flexible Slot form factor is 25% smaller than the previous-generation Common Slot format. Tool-less hot-plug access makes it easier to service the system without removing it with tools.
HPE lists compatibility with ProLiant Gen10, Gen10 Plus and Gen11 servers, selected Apollo Gen10 and Gen10 Plus systems, and Alletra 4100 data-storage servers. On Gen10 and Gen10 Plus systems, maximum output is 1600W. The kit can serve as a replacement or additional power supply in these supported deployments, subject to that platform limit.
