300 W 1U server power supply

The Athena Power AP-U1ATX30P8 is a 300 W single-unit supply built for 1U IPC server chassis. It delivers power through a 20+4 pin ATX connector and carries 80PLUS Bronze certification. The compact form factor suits dense rack or desktop deployments where space is limited.

Check chassis height and connector needs

Verify that your chassis accepts a 1U high power supply and that the motherboard uses a standard 20+4 pin ATX input. Ensure the total system draw stays within the 300 W rating. Confirm the unit’s physical depth matches the chassis mounting rails before ordering.

Dual fans exhaust heat front to back

Front and rear fans move air through the supply, pulling internal heat out the front panel. Thermal speed control adjusts fan RPM to the actual heat load. Active PFC and full-range input regulate power automatically. The design leaves internal drive bays and expansion slots unobstructed.

Questions about this item

Does the 20+4 pin connector come attached or must I buy cables separately?

The unit includes a fixed 20+4 pin ATX connector; no modular cables are offered with this model.

Is the 300 W 80PLUS Bronze unit the only capacity available in this series?

The listing describes a single 300 watt 80PLUS Bronze configuration; no other wattage or efficiency tier is shown for this part number.

Will the dual-fan thermal control keep a 1U server quiet under a 300 W load?

Front and rear fans run under thermal speed control, so noise rises with heat but stays proportional to the actual load inside the chassis.
