Abstract
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.
