Replace Power 480 W ATX PSU for HP systems

This Replace Power ATX power supply provides 480 watts of rated output and is built as a direct replacement for HP part numbers 5188-2625, 5188-2627, 5188-2626 and 5187-5008. It uses a single fan for cooling and includes over-voltage, over-power and short-circuit protection. The unit is supplied new and has passed 100 % hi-pot, function and burn-in testing at 50 °C ambient temperature.

Suitable for HP Pavilion owners needing

The unit fits the listed HP part numbers and delivers 420 W maximum power on the 12 V rail, so it supports the original system configuration. Builders who need higher wattage, modular cables or a different form factor should look at other options. It is not intended for custom builds that require non-standard pin-outs or additional PCIe connectors.

Continuous-load behaviour with single-fan cooling

Under sustained load the power supply maintains its rated output while the single fan manages thermals within the tested 50 °C environment. Protection circuits engage cleanly if voltage or current exceeds safe limits. The burn-in validation suggests stable operation during extended sessions rather than only short bursts.

Questions about this item

Which HP part numbers must my chassis already support for this 480W ATX unit to fit?

The supply replaces HP part numbers 5188-2625, 5188-2626, 5188-2627 and 5187-5008, so your case must accept one of those.

Will the single fan keep an older motherboard with a 12V rail cool enough under load?

The unit was burn-in tested at 50°C ambient and delivers up to 420W continuous on the 12V rail, so a legacy board should stay within thermal limits.

How can I verify the over-voltage and short-circuit protections are active after installation?

Power the system on; the supply runs its internal self-test at start-up and the fan spins, confirming the protection circuits are functional.
