420W ATX power module

This 420W ATX power module from Replace Power is built as a direct replacement for several HP Media Center desktops including the m7050e, m7050y, m7060n, m7100y CTO, m7163w and m7167c. It delivers standard ATX output through a single 80mm fan and a grey chassis.

Suits owners of listed HP Media Center models

It suits owners of the listed HP Media Center models who need a like-for-like 420W unit with the original connector layout. Builders working on custom ATX chassis or systems that require PCIe power, multiple SATA drives or higher wattage should look elsewhere.

Fits HP Media Center bays with switchable input

The unit fits the proprietary bays of the compatible HP models and accepts 110V or 220V input via a manual switch. Included cables provide one SATA connector, a 20+4 pin ATX connector, a 12V ATX connector, two large peripheral connectors, two short peripheral connectors and one small peripheral connector, freeing the builder from sourcing adapters.

Questions about this item

Does the RPSU-C99-xa include the 20+4 pin ATX and 12V ATX cables my motherboard needs?

Yes, it ships with one 14-inch 20+4 pin ATX connector and one 14-inch 12V ATX connector for the motherboard.

Will the grey 80mm fan unit fit the original HP Media Center m7050e chassis mounting points?

The supply is built as a direct replacement for the listed HP Media Center models including the m7050e, so the mounting holes and 80mm fan align with the original chassis.

How can I confirm the 110V/220V switch is set correctly after installation?

Before powering on, check the rear voltage selector; it should show 110V for North America or 220V for most other regions, matching your local mains supply.
