Replacement ATX unit for legacy HP systems

This 300-watt ATX power supply replaces a wide range of original HP and third-party units. It matches the 0950-4107 part number and fits systems that shipped with 250-watt models. The grey enclosure and single fan keep the original form factor intact.

300 watts with 24-pin and SATA connectors

The unit delivers 300 watts across its rails and includes one 24-pin ATX connector, one 12-volt ATX connector, two SATA power connectors, three Molex connectors and one floppy connector. This covers most period motherboards and a pair of SATA drives, but leaves no spare SATA leads for additional storage.

Built-in overload protection and compact mounting

Voltage overload protection is integrated to guard connected components. Dimensions of 3.3 by 5.9 by 4 inches allow direct mounting in the original chassis without modification. The single 24-pin and single 12-volt ATX connector limit use to boards with those exact headers.

Will the 24-pin ATX connector fit the motherboard I kept from my older HP?

How can I confirm the 300-watt unit is delivering stable power once installed?

The supply includes built-in voltage overload protection; if the system posts and runs without shutdowns under load, the protection circuit is functioning.
