Compatible HP Desktop Power Supply

This 550W ATX power supply replaces the original unit in HP Pavilion P7-1010, P7-1003W, 550-110 and Envy H8-1534 desktops. It delivers 550 Watts of power through a standard 24-pin main connector and a 4+4-pin CPU connector. The unit fits the standard ATX form factor used by these specific HP models.

Suitable For Standard HP Upgrades

This unit suits owners of the listed HP Pavilion and Envy desktops who need a direct replacement for a failed or ageing power supply. It provides the exact connectors required by those motherboards. Builders working on custom ATX chassis, systems requiring additional PCIe power cables, or proprietary small-form-factor HP units not listed above should look at other options.

550W Output With 24-Pin And 4+4-Pin

The single specification that decides fitment is the combination of 550W rated output, a 24-pin ATX motherboard connector and a 4+4-pin CPU power connector. These three details match the power and connector requirements of the compatible HP models exactly. Verify your motherboard uses these same connectors before purchasing.

Questions about this item

What does the 550W rating mean for a desktop build?

The 550W rating is the maximum continuous power the unit can deliver to components; it suits typical mid-range systems with a single graphics card.

What does the AT type designation indicate for motherboard compatibility?

The AT type means this unit follows the legacy AT form factor and pin-out, so it will not fit standard ATX motherboards without an adapter.

Will the 24-pin and 4+4-pin connectors reach the motherboard sockets in a standard tower case?

The fixed cables are sized for typical ATX chassis layouts, but exact reach depends on your specific motherboard and case dimensions.
