Replace Power RPMPS3420-12 300W ATX power supply

SKU CH-VFY1-BRV56 MPN RPMPS3420-12

300W ATX replacement supply with 24-pin, 4-pin CPU, three SATA, PCI-E 6-pin and multiple legacy connectors

  • Fan configuration1
  • Product typeATX
  • Product weight2
  • 300W output powers demanding desktop builds
  • 20+4 pin ATX connector fits 20-pin and 24-pin motherboards
  • Single fan keeps the unit cool under load
  • Over-voltage protection safeguards connected components
  • Multiple SATA, LP4, PCI-E and auxiliary connectors cover a wide range of peripherals

Compatible replacement PSU

This 300W ATX power supply replaces Hipro HP-A2027F3, HP-A2317F3, HP-D3537F3R and HP-P3017F3 LF units in Gateway LX6200, LX6810, LX6820 and S-5000D systems. It provides a 20+4 pin motherboard connector, a 4-pin P4-12V connector, three SATA 15-pin connectors, one PCI-E 6-pin connector, three LP4 4-pin connectors, one floppy 4-pin connector, one auxiliary 6-pin connector and one HP Video 4-pin connector.

Straightforward swap

The unit fits the same mounting points and uses standard ATX wiring, so installation is a direct replacement for the original Hipro modules. Builders must verify that the 300W rating matches the system's power draw and that the included connector set covers every peripheral in the chassis.

For Gateway desktop owners

This suits owners of the listed Gateway models who need a new-old-stock replacement for a failed Hipro supply. It does not suit builders who need more storage connectors than the three SATA ports provided, nor those whose systems require a higher wattage or additional PCI-E power cables.
