Replacement for Legacy HP Systems

This ATX power supply from Replace Power is built as a direct swap for several older HP Pavilion desktops including the a1419h a1420 a1423w a1428x a1340n a1440n and a1445n models. It delivers the standard connectors those systems expect so the machine powers on without adapter cables.

80 mm Fan Cooling and Switchable Input

A single 80 mm fan handles airflow while over current over power and over voltage protection circuits guard the rails. The unit accepts 115 V or 230 V input via a manual switch making it suitable for different mains supplies.

Compact Depth Frees Case Space

At 5.9 inches high and 3.4 inches wide the reduced depth chassis fits tight legacy enclosures where longer units would foul drive cages or motherboard headers. The connector set includes one SATA one 20+4 pin ATX one 12 V ATX two large peripheral plugs and one 6 inch small power lead covering the original wiring loom.

Questions about this item

How do I install the RPSU-C99-19 and which step is often missed?

Mount the unit using the standard ATX screw holes, connect the 20+4 pin ATX, the 12V ATX, one SATA, two large peripheral and one small 6-inch connector, then set the 115/230 V switch to match your mains voltage before powering on.

What maintenance or replacement will the RPSU-C99-19 need later?

The single 80 mm fan is the only moving part; clean dust from its intake every 6–12 months and replace the fan if noise or speed drops appear.

What limit appears first on the RPSU-C99-19 under sustained load?

The 80 mm fan’s airflow capacity is the first bottleneck; prolonged high draw will raise internal temperatures until the over-temperature protection engages.
