Redundant 2 x 500W Server PSU

This Athena Power AP-RRP4ATX6508 is a redundant EPS12V power supply delivering two 500W modules in a mini-redundant form factor. It targets server builders and operators who require continuous uptime and hot-swap capability for critical workloads. The unit provides N+1 redundancy so a single module failure does not interrupt operation. It suits environments where power reliability is a primary design requirement.

Hot-swap EPS12V with 20+4Pin main connector

The supply accepts 88 to 264 Volts AC at 47 to 63 Hz and fits standard redundant bays measuring 5.9 x 3.4 x 8.9 inches. Each module shares the load equally during normal operation and the surviving module instantly assumes the full load if its partner fails. Active PFC and a remote ON/OFF function simplify integration. The 20+4Pin main connector mates directly with compatible server mainboards without adapters.

500W per module with 80 PLUS efficiency

Each module delivers up to 500W maximum power with combined rails rated at +12V x 3@11A, +5V@11A, +3.3V@11A and auxiliary outputs at lower currents. The 80 PLUS certification reduces waste heat, supporting the rated MTBF of 100,000 hours at +25°C on maximum load. Headroom covers typical dual-socket server configurations; loads exceeding 500W per module or sustained operation above 40°C at full output exceed the design envelope.
