Replacement ATX PSU for HP Pavilion 550-106a

This Replace Power ATX supply is built as a direct replacement for the HP Pavilion 550-106a desktop. It delivers standard ATX power through a 20+4 pin main connector and a +12V 4-pin CPU connector. The unit includes three SATA power connectors and one 6-pin connector for internal drives or expansion cards. It suits owners restoring or upgrading that specific chassis.

Single-fan thermal profile

A single fan manages airflow through the grey enclosure during normal operation. Power draw follows the load presented by the host system and installed components. Acoustic output will vary with fan speed under different thermal conditions. No further thermal or noise specifications are provided.

Upgrades the original factory unit

This supply replaces the original power supply shipped with the 550-106a when that unit fails or when added drives require more SATA power connectors. The jump is worthwhile if the existing PSU no longer starts reliably or lacks the 6-pin connector needed for a discrete graphics card. Builders needing more than three SATA connections or a different form factor cannot use this model.

Questions about this item

How do I connect the 20+4 pin ATX and 4-pin +12V cables to the motherboard?

Plug the 20+4 pin ATX connector into the main board socket and the +12V 4-pin connector into the CPU power header; the 6-pin cable goes to the graphics card if required.

Will I need to replace the single fan or clean it later?

The unit uses one internal fan; periodic dust removal with compressed air keeps airflow steady and avoids overheating.

What limits sustained load before the supply shuts down?

The 550 W rating and fixed connector set cap continuous delivery; exceeding rated output triggers protection.
