According to one embodiment, an adjustable power capacity Power Supply Unit (PSU) includes a circuit coupled within a feedback loop of the PSU that is controlled by an internal processing system. The feedback loop configured to carry a feedback signal for regulating an output power of the PSU. The processing system includes executable instructions that may be executed to receive an output power capacity set point that represents a programmed output power rating of the PSU, and control the circuit to modify the feedback signal so that the PSU generates output power at the programmed output power rating. The programmed output power rating set on the PSU being less than an actual output power rating of the PSU.

Adjustable power capacity power supply unit (PSU) system and method

A system for controlling voltage operation of a power supply unit (PSU) for an information handling system. If the PSU is established as a High-Line power supply and is a dual wattage unit, Low-Line capabilities are disabled and the PSU turns off if power drops below a High-Line minimum voltage. If the PSU is established as a Low-Line PSU or is not dual wattage unit, the PSU is maintained in a current operational state and is either reset or turned off before making changes.
