Replacement ATX Power Supply for HP Compaq
This 420W ATX power supply replaces several older legacy units used in HP Compaq systems. It matches part numbers 5188-0131, 5188-0129 and 5188-0130 among others. The reduced depth design improves compatibility with compact chassis. It is sold new and ready for installation.
Single 12V Rail Output Rating
The +12V rails deliver 8A each, providing a combined 12V capacity that determines whether this unit can power your components. Over current and over power protection circuits guard against faults. Input voltage accepts 115 / 230 V at 50 / 60 Hz. Operating temperature range spans 0 C to 50 C under full load.
Connector Bundle for Legacy Builds
The cable set includes one ATX 20+4 pin connector, one P4 12V 4-pin connector, three SATA 15-pin connectors, three LP4 4-pin connectors and one floppy 4-pin connector. This mix supports older motherboards, IDE drives and floppy devices. Systems requiring additional SATA or PCIe power cables will need adapters or a different unit.
