Product information

Description

HP 865438-B21 is a server power supply unit rated at 800 W with an AC input range of 200–240 V and a stated efficiency of 96%. It is built for use in compatible HP systems where continuous, high-capacity power delivery is required. The unit’s grey housing conforms to rack-mounted server aesthetics and is intended for installation in data centers, enterprise server rooms and other environments that demand reliable, redundant power.

Advantages

The 800 W output and high conversion efficiency reduce energy losses and lower operating costs compared with lower-efficiency supplies. Its wide AC input range supports international mains voltages within the 200–240 V band and maintains stable output under typical server load conditions. The compact, industry-standard form factor and grey finish simplify integration into existing racks and chassis designed for compatible HP modules.

Suitable for

  • Rack-mounted servers in data centers and colocation facilities
  • Enterprise server rooms requiring redundant or hot-swappable power supplies
  • High-availability applications with sustained load demands
  • Environments where high efficiency is prioritized to reduce heat and energy costs

Key specifications

  • Output power: 800 W
  • AC input voltage: 200–240 V
  • Efficiency: 96%
  • Form factor: server-compatible hot-swap module (grey housing)
  • Cooling: active cooling compatible with server chassis airflow (internal fan)

How to use

Install the power supply into a compatible HP server or chassis following the server manufacturer’s installation procedure. Ensure the system is powered down or that the chassis supports hot-swap insertion if replacing an active module. Connect the AC mains to a correctly rated power distribution unit or outlet within the 200–240 V range and verify proper seating and locking of the module. After installation, confirm that the server recognizes the power supply and monitor status indicators or management software for normal operation.

Usage recommendations

For reliable long-term operation, use this PSU in systems with compatible hot-swap bays and maintain adequate rack airflow. Match the supply to system power requirements and consider redundant configurations for critical workloads. Regularly monitor temperature and status LEDs and replace units showing fault indicators to maintain availability.
