180 W Replacement Power Supply

This 180 Watt ATX unit replaces the HP 5189-3964 or Bestec ATX-180D5WA in compatible desktops. It delivers the original power rating through a standard ATX form factor with a single cooling fan. The 2.2 kg module fits the same mounting points as the factory supply. It is not for systems that require a higher wattage unit.

Direct ATX Swap for HP Desktops

The supply uses the standard ATX connector layout so it plugs into the existing motherboard and drive cables without adapters. One fan handles airflow while the chassis vents handle exhaust. No extra cables or brackets are included in the package. Builders needing modular cabling or higher continuous output must choose a different unit.

Questions about this item

Will the 180 W rating limit sustained loads?

The unit is a 180 W replacement module; continuous draw above that level will trigger protection and shut the system down.

How much heat and noise does the single fan produce during all-day operation?

One fan cools the 180 W ATX module at 2.2 kg; expect moderate airflow noise and noticeable case warmth under full load.
