Replacement PSU for HP Media Center

This 420W ATX power supply replaces the original unit in HP Media Center models a1206n, m7077c, m7360n, a1430n, m8050br and m1082n. It fits standard ATX mounting points and uses a switchable 110V/220V input for worldwide mains compatibility. The grey enclosure houses a single cooling fan. It is built for owners of those specific HP desktops who need a direct swap.

Connector layout and daily use

The unit provides a 15-inch SATA connector, a 14-inch 20+4 pin ATX motherboard plug, a 14-inch 12V ATX plug, two 15-inch large peripheral connectors, two 6-inch large peripheral connectors and one 6-inch small peripheral connector. Cable lengths range from 6 to 15 inches to reach drives and motherboard headers in typical mid-tower chassis. A single 80mm fan handles airflow. Builders working in very compact cases should verify clearances before ordering.

420W continuous rating decides fit

The 420W maximum output is the single figure that determines whether this unit can support your installed components. Add the rated draw of your CPU, graphics card, drives and expansion cards; if the total approaches or exceeds 420W, a higher-capacity supply is required. No other specification in the data overrides this limit.
