Replacement ATX Power Module

This Replace Power FSP300-ATXPA-4 unit is a 300 W ATX power supply designed as a direct replacement for the HP Pavilion a1742n 8400F. It fits standard ATX cases and uses a single fan for cooling. The grey chassis weighs 0.1 in the listed unit.

Capacity and Headroom

The 300 W rating supports typical office or home PCs with integrated graphics and a few drives. It provides one 20+4-pin ATX connector, one 4-pin ATX12V connector, three SATA power connectors, two peripheral connectors and one floppy connector. High-efficiency operation with low ripple and noise is specified alongside over-voltage protection. Systems with discrete graphics cards or many drives will exceed the available power and connector count.

Upgrade Context

This unit replaces a failed or ageing original power supply in the named HP Pavilion model and compatible systems. The jump is worth it when the existing PSU no longer delivers stable voltage or has missing connectors for added SATA drives. It is not for builds that require higher wattage, additional PCIe power connectors or modular cabling.

Questions sur cet article

Will the 20+4-pin ATX and 4-pin ATX12V connectors on the FSP300-ATXPA-4 fit the motherboard in my HP Pavilion a1742n?

Yes, the 20+4-pin ATX and 4-pin ATX12V connectors match the standard ATX layout used by the HP Pavilion a1742n motherboard.

How can I confirm the FSP300-ATXPA-4 is delivering stable power after installation?

The unit includes over-voltage protection and low ripple and noise output; a system that boots reliably and runs without random shutdowns indicates it is working as intended.

Does the FSP300-ATXPA-4 box include SATA power cables for my drives, or must I buy them separately?

Three SATA power connectors are built into the unit, so no separate SATA cables are required for up to three drives.
