Athena Power AP-U3ATX80FEP8 800W server power supply

800W single server power supply

This Athena Power unit delivers 800 watts of continuous power for 3U rack servers and high-density workstations. It operates as a single non-redundant module with active PFC meeting EN61000-3-2. The supply accepts a wide 88 to 264 volt input range at 47 to 63 Hz. It is built for environments that demand steady output across variable mains conditions.

20+4 pin ATX with dual EPS and PCIe connectors

The unit provides one 20+4 pin main connector, one 4 pin P4-12V and two 8 pin EPS-12V cables for multi-socket motherboards. Two 6 pin and two 6+2 pin PCIe leads support add-in accelerators or GPUs. Eight SATA 15 pin and two Molex 4 pin connectors handle storage arrays and peripherals. A floppy 4 pin lead is also included for legacy devices.

Dual 12V rails rated at 32 amps each

The +12V1 and +12V2 rails supply 32 amps apiece for processor and add-in card loads. Minor rails provide 20 amps on 3.3 volts and 22 amps on 5 volts. Hold-up time is 17 milliseconds at nominal input. Protection circuits cover over-voltage, short-circuit and overload events. The design suits builds that stay within these rail limits; configurations needing higher per-rail current or redundant supplies will require a different unit.
