Replacement PSU for HP Pavilion 550-115a

This Replace Power unit is a new ATX power supply built specifically for the HP Pavilion 550-115a desktop. It serves as a direct replacement or upgrade for the original PSU in that model. The grey chassis houses a single cooling fan.

Connectors: 20+4 ATX, 4-pin +12V, SATA, 6-pin

The unit provides a 20+4 pin ATX motherboard connector and a +12V 4-pin power connector for the CPU. Storage and peripherals are supported by three SATA connectors and one 6-pin power connector. A mini-SATA connector for 5-inch devices is also included.

Upgrades the factory PSU in the 550-115a

This supply replaces the original power unit when it fails or when added components demand more reliable delivery. The jump is worth it if the current PSU cannot sustain the installed hardware or if the system shows instability under load. Builders needing different connector types or higher rated output should look elsewhere.
