Replacement Power Supply for HP Desktops

This unit replaces the original power supply in HP models A465w A475c A500n A500y A510e A510n A518x A520n. It fits a standard ATX slot while the reduced depth increases case compatibility. The grey enclosure uses a single 80 mm fan for cooling and includes a fixed cable set with a 20+4 pin motherboard connector, a 4 pin CPU connector, three SATA connectors, two Molex connectors and one floppy connector.

Sustained Load Behaviour

The supply delivers a continuous 280 watts across the +3.3 V +5 V +12 V1 +12 V2 -12 V and +5 VSB rails with a peak capacity of 420 watts. Low ripple and noise specifications help maintain stable voltages during extended operation. Hold-up time is at least 17 ms at nominal input so brief mains interruptions do not immediately drop the output. Rise time stays below 70 ms ensuring smooth start-up under load.

Thermals Noise and Power Draw

An 80 mm fan provides airflow for long-life performance while keeping acoustic output low in normal use. The unit accepts AC input from 110 V to 220 V at 47 Hz to 63 Hz making it suitable for worldwide mains without a selector switch. Hi-Pot testing and ROHS CE compliance confirm electrical safety and environmental standards. Power factor and efficiency figures are not supplied.
