Hot-plug power supply design
Left-hand module orientation
HPE MPN 865408-B21
Server power supply kit
Designed for supported HPE platforms

Keep supported HPE server platforms powered with a 500 W hot-plug left-hand power supply kit. In dense infrastructure, power modules are not just spare parts — they are the difference between a controlled maintenance event and an avoidable outage. Hot-plug design matters when uptime is measured in service windows, not marketing claims. This kit is built for environments that need quick replacement without taking the full system offline, helping operations teams preserve continuity while addressing a failed or aging power module. The left-hand form factor is important for exact chassis fit and service planning. For procurement teams, that specificity justifies the part over generic alternatives: it is selected for compatibility, replacement speed, and the operational discipline expected in enterprise server fleets. When a platform is carrying production workloads, the right power supply kit protects both availability and the maintenance schedule.
