Replacement PSU for HP Pavilion

The Replace Power FSP300-ATXPA-5 is a 300 W ATX power supply designed as a direct replacement for HP Pavilion a6142n a6120n a6009n systems. It delivers standard ATX power through a grey chassis with a single fan. The unit includes over voltage protection and low ripple and noise output for stable operation.

Check connectors and chassis fit

Verify that your motherboard uses a 20+4-pin ATX connector and a 4-pin ATX12V connector for CPU power. Ensure the case accepts a standard ATX form factor unit and that the single fan orientation matches your airflow path. Confirm the peripheral, floppy and three SATA power connectors match your drive count before ordering.

Upgrades proprietary HP power supplies

This unit replaces the original equipment power modules found in the listed Pavilion models when the factory supply fails or cannot support added drives. The jump is worth it when the existing PSU lacks sufficient SATA connectors or shows signs of voltage instability. It is not for builders who need higher wattage for discrete graphics cards or modern multi-core processors.
