Replacement PSU for HP A1310y A1312n A1314n A1319h

This unit replaces the original power supply in specific HP desktop models including the A1310y A1312n A1314n A1319h A1320n and A1323w. It uses a standard ATX form factor with reduced depth so it fits the existing chassis without modification. The built-in cabling provides the connectors those systems expect. Grey colour matches the original aesthetic.

ATX connector limits and rail behaviour

The 24-pin motherboard connector splits as 20+4 for backward compatibility. A single 4-pin CPU power lead is provided. Three SATA 15-pin connectors and two Molex 4-pin connectors serve drives and peripherals. One floppy 4-pin lead remains for legacy devices. The unit delivers +5V -5V +12V1 +12V2 +3.3V -12V and +5V-SB rails. AC input accepts 110V or 220V at 47 to 63 Hz.

280 W continuous capacity headroom

Total continuous output is rated at 280 watts with a 420 watt peak figure. Hold-up time is a minimum of 17 ms at nominal input. Rise time stays below 70 ms. The 80 mm fan maintains airflow for stable long-term operation. Systems demanding more than 280 watts sustained will exceed this supply's capability. Builder configurations requiring additional PCIe power leads or higher 12 V current cannot use this unit.
