HP Pavilion ATX power supply

The HP 5188-0129 is a 300 watt ATX Sata power supply built for HP Pavilion desktops. It delivers the rated output through a standard ATX form factor and includes Sata power connectors for internal drives. The unit is supplied new and matches the original equipment specification for compatible Pavilion systems.

Replaces the original Pavilion PSU

This supply replaces a failed or degraded factory unit in an HP Pavilion desktop that requires a 300 watt ATX Sata power source. The swap is worth it when the existing power supply no longer starts reliably or cannot sustain load. It is not for builds that need higher wattage or non-Sata drive power.
