Replacement ATX power supply

The Replace Power RPSU-C99-14 is a 420W ATX power supply designed to replace faulty units in specific HP Media Center models including m7750n, m7757c, m7760la, m7760n, m7763w and m8071kr. It fits standard ATX cases and uses a single 80mm fan for cooling. The grey unit weighs 0.1 and targets owners of those listed desktops needing a direct swap.

Connector limits and voltage switching

This unit provides one 15-inch SATA connector, one 14-inch ATX connector supporting both 20-pin and 24-pin motherboards, one 14-inch 12V ATX connector, two 15-inch large power connectors, two 6-inch large power connectors and one 6-inch small power connector. A 110V/220V switch allows manual selection of input voltage. No other interfaces or modern power standards are present.

Fixed 420 watt capacity

The single specification that decides fit is the 420W rated output; systems requiring more power or PCIe graphics connectors cannot use this supply. Builders needing higher wattage, modular cabling or 80 Plus certification should select a different unit. The fixed cable lengths and connector count suit only the listed HP replacements or similar legacy builds.

商品問答

Should I pick the 420W version or a different capacity?

The RPSU-C99-14 is supplied only as a 420W unit, so there is no alternative capacity to choose from.

What does the 420W rating mean once the supply is installed in my PC?

It indicates the maximum combined power the unit can deliver to the motherboard, drives and peripherals through its ATX, 12V, SATA and Molex connectors.

Which ATX standard does the 20+4 pin connector follow, and what does that cap in practice?

The 14-inch 20+4 pin connector fits both 20-pin and 24-pin motherboards, limiting use to boards that accept the standard ATX power pinout.
