Replacement PSU for HP Pavilion and Elite desktops

This 420W ATX power supply replaces the original HP 5187-1098 unit found in Pavilion a1300la, a1410n, d4990y CTO and Elite HPE-210Y systems. It delivers 110V or 220V input via a manual switch and uses an 80mm fan for cooling. The grey chassis weighs 0.1kg and fits standard ATX mounting points.

ATX connector limits and cable reach

The single 14-inch ATX connector supports both 20-pin and 24-pin motherboard headers, while the 14-inch 12V ATX plug feeds the CPU. One 15-inch SATA connector serves a single drive, and two 15-inch plus two 6-inch large peripheral connectors handle older devices. A 6-inch small floppy connector is also included. Cable lengths restrict routing in larger chassis.

Upgrade from a failed or undersized OEM unit

This unit replaces a faulty original supply or one that cannot sustain the 420W rating under load. The jump is worth it when the existing PSU has failed, lacks the 20+4 ATX flexibility, or cannot power the installed SATA and peripheral devices. It is not for builds needing multiple SATA drives, PCIe graphics power, or higher continuous wattage.
