Compact 1U server power supply

The Athena Power AP-U1ATX30A is a 300W single-unit PSU built for 1U rackmount chassis. It fits space-constrained industrial servers that need standard ATX power delivery in a shallow 1.55-inch height. The unit includes a 20+4-pin main connector, one 4-pin CPU connector, three Molex, two SATA and one floppy connector. It is not suited for builds that require PCIe power cables or redundant hot-swap capability.

Dual 40mm fans with auto speed control

Two ball-bearing fans spin under a smart thermal controller that adjusts speed to load and temperature. At full 300W output and 25°C ambient the design targets 100,000 hours MTBF. Input accepts 88–264 V at 47–63 Hz with active PFC meeting EN61000-3-2. Hold-up time is at least 17 ms at nominal voltage. Protections cover over-voltage, short-circuit and overload conditions.

Replaces older 1U units lacking active PFC

The jump is worthwhile when a legacy supply cannot deliver stable +12V current up to 15A or lacks SATA power for current drives. It also upgrades systems that need the 20+4-pin ATX v2.2 header instead of a 20-pin-only design. Builds requiring 6-pin, 8-pin or 6+2-pin PCIe cables must look elsewhere.

Questions sur cet article

How do I install this 1U server power supply and which step is often missed?

Slide the unit into the 1U chassis bay, secure it with the mounting screws, connect the 20+4Pin main connector, the 4-pin CPU connector, two SATA connectors and three Molex connectors, then plug the IEC power cord; the step often missed is attaching the 4-pin CPU power cable.

What maintenance or replacement will this unit need later?

The dual 40mm ball-bearing fans are the only moving parts; after long-term operation they may require cleaning or replacement, while the electrolytic capacitors inside will eventually age and the whole unit should be replaced once it reaches the 100,000-hour MTBF rating.

What limit appears first when this supply runs at full 300W load continuously?

The +12V rail is rated for a maximum of 15A, so sustained loads drawing more than 15A on the 12V line will trigger overload protection before the overall 300W or thermal limits are reached.
