Direct replacement for HP Pavilion desktops

Suitable for owners restoring those models

Builders fitting standard ATX boards or cases requiring different connector lengths should look elsewhere. The fixed cable lengths and HP-specific pin-outs limit use outside the listed chassis.

The harness includes one 14-inch 20+4 pin ATX connector, one 14-inch 12V ATX12V connector, one 15-inch SATA connector, two 15-inch and two 6-inch large peripheral connectors plus one 6-inch small connector. Input voltage is selectable between 110V and 220V.

Questions about this item

How loud and hot does the 80 mm fan get when the 420 W unit runs all day?

The single 80 mm fan provides active cooling; noise and temperature will depend on case airflow and load, but the unit is designed for continuous desktop operation.

Which existing cables or connectors must my HP Pavilion a1330n, a1637c or a1726x already have for this replacement to work?

Your system needs a standard 20- or 24-pin ATX motherboard socket, a 12 V ATX12V CPU connector, SATA drive ports and peripheral power sockets — all supplied by the unit.

Will the switchable 110 V / 220 V input and the 20+4 ATX connector work with older motherboards that only have a 20-pin socket?

Yes, the 20+4 pin ATX connector fits both 20-pin and 24-pin motherboards, and the voltage switch lets you match local mains without changing hardware.
