600W Redundant Server PSU

The Athena Power AP-RRU2ATX608 is a 600W redundant power supply built for 2U server chassis. It delivers 48A on the +12V rail and 20A each on the 3.3V and +5V rails. The unit suits administrators who need continuous uptime from a hot-swap redundant module.

Thermals and Power Draw

The supply operates from 0°C to +50°C at full load with an MTBF of 100000 hours at +25°C. Hold-up time is 17 ms minimum at nominal input, and rise time stays below 20 ms. Input frequency range covers 47 Hz to 63 Hz for global mains compatibility.

Connectors and Mounting Implications

The module provides one 24(20+4) pin ATX connector, one P4 4-pin, two EPS 8-pin, two PCIE 6+2-pin, three SATA 15-pin and three Molex 4-pin leads. Its 3.30" x 2.99" x 9.84" form factor fits standard 2U redundant bays. Builders needing more SATA or PCIE outputs than listed will require additional distribution.

Questions about this item

How do I install the redundant modules in a 2U rack and what step is often missed?

Slide each module into the chassis until it locks, connect the ATX 24-pin, EPS 8-pin x2, PCIe 6+2-pin x2, SATA x3 and Molex x3 cables, then verify both AC inlets are powered; the step often missed is seating the second module fully so the redundant bus engages.

Which component will need replacement first and how can I tell?

The internal cooling fans typically wear out before the 100,000-hour MTBF rating; listen for bearing noise or watch for rising chassis temperatures above 50 °C as early indicators.

What limit appears first when the supply runs at full 600 W continuously?

The +12 V rail is rated at 48 A; sustained loads that approach this current will hit the over-current protection before the 17 ms hold-up time or thermal limits become factors.
