Compatible HP Pavilion 420W ATX PSU

This 420W ATX power supply replaces the original unit in HP Pavilion a1230n, a1235c, a1243w, a1245c, a1250n, a1253w and a1267c desktops. It delivers 420 watts through a single 80mm fan cooled grey chassis. The unit includes a switchable 110V or 220V input for global mains compatibility. It is a direct swap for a failed or ageing factory PSU.

Suits owners of listed HP Pavilion models

Builders assembling a new custom system should look elsewhere because the connector lengths and form factor are tailored to the specific Pavilion chassis. Users needing higher wattage for discrete graphics cards or many drives cannot use this 420W unit. Systems requiring a different main power pinout or proprietary motherboard connector are not supported.

20+4 pin ATX motherboard connector

The supply provides a 14-inch 20+4 pin ATX connector that fits both 20-pin and 24-pin motherboard headers found in the target HP models. One 15-inch SATA connector, one 14-inch 12V ATX connector, two 15-inch large peripheral connectors, two 6-inch large peripheral connectors and one 6-inch small peripheral connector complete the loom. This specific connector mix decides fitment.
