Single 400W server supply

The Athena Power P2H-5400V delivers 400W in a single 2U form factor. It targets IPC and server builds that need one reliable unit rather than a redundant pair. The unit ships new and fits standard server chassis bays.

Sustained 400W at 50 °C

Rated for continuous full-load operation up to 50 °C, the supply maintains its 400W output without derating. MTBF is 100000 hours at 25 °C under maximum load, and hold-up time reaches 17 ms at nominal input. The 12V rail supplies 32A for CPU-heavy workloads.

Fixed cables for 2U installs

A 24-pin ATX, one 4-pin P4, two 8-pin EPS, three SATA, three Molex and two floppy leads are permanently attached. The cable set covers typical dual-socket boards and drive arrays in 2U enclosures. Input range spans 88-264 V at 47-63 Hz for global deployment.

Questions about this item

How much noise and heat does the 400W unit produce when running all day at full load?

The supply is rated for continuous operation at up to 50 °C and carries a 100,000-hour MTBF at 25 °C, indicating the cooling system is built for sustained full-load use.

What connectors must my motherboard and drives already provide for this supply to work?

Your board needs a 24-pin ATX socket, one 4-pin P4 12 V header and two 8-pin EPS 12 V headers, while drives require three SATA power ports, three Molex ports and two floppy ports.

Will the dual EPS 12 V 8-pin connectors work with my older single-CPU server board?

Yes, the two EPS 12 V 8-pin cables are compatible with single-socket boards that accept an 8-pin or 4+4-pin CPU power plug; simply leave the second connector unused.
