1U 400W server power supply

The Athena Power AP-U1ATX40P8 is a single 400W unit built for 1U rackmount servers. It delivers +12V across two rails at 11A each with a 20+4 pin main connector and an EPS 8-pin CPU connector. The supply suits integrators assembling dense compute nodes that require standard ATX and EPS power in a compact chassis.

80 PLUS Bronze 88-264V AC input

Efficiency meets 80 PLUS Bronze certification with active PFC compliant to EN61000-3-2. The full-range input accepts 88 to 264 volts AC at 47 to 63 Hz without manual switching. Hold-up time is rated at 17ms minimum at nominal voltage. The unit provides over-voltage, short-circuit and overload protection but lacks redundant or hot-swap capability for high-availability clusters.

Dual-fan cooled 3.0lb chassis with SATA

Two internal fans are managed by a smart auto speed controller for thermal balance. The enclosure measures 3.93 by 1.57 by 7.87 inches and weighs 3.0lbs. Connectors include three SATA, two PCIe 6-pin, two Molex, one floppy and dual P4 4-pin plugs. Operating temperature range is 0°C to 50°C at full load with MTBF of 100,000 hours at 25°C.

Perguntas sobre este artigo

Should I choose a single or redundant 400W supply for my 1U server?

This model is a single 400W unit; it does not support redundant operation.

What does the 400W rating mean for actual 12V delivery in a server build?

The two 12V rails each provide up to 11A, giving a combined 12V capacity within the 400W total.

Does the EPS 80 PLUS Bronze rating limit the input voltage range I can use?

The unit accepts 88–264 V AC at 47–63 Hz, so the efficiency rating does not restrict the input range.
