The HP power supply unit is designed for HP Compaq dc7100 series desktop computers. It is an internal PC power supply unit with switching PSU technology, likely corresponding to a 340W configuration for dc7100 tower models, although lower wattage versions are also available for other form factors, such as SFF. It is compatible with HP desktop systems from the dc7100 family and may also be listed as a replacement for dc5100, dc7600, and dc7700 SFF systems. The product is intended as an alternative power supply for supported HP systems and is usually sold only as a power supply unit, without additional accessories unless specified otherwise by the seller.
