1. An information handling system comprising:
a power supply unit having an input for receiving an alternating current input waveform and converting the alternating current input waveform into a direct current waveform on a bulk capacitor for storing charge; and
a controller configured to, based on at least one parameter of one or more information handling resources of the information handling system, determine a configurable under-voltage threshold defining a minimum direct current voltage to be delivered by the power supply when the alternating current input waveform is withdrawn;
wherein the at least one parameter comprises a minimum voltage requirement of a particular information handling resource of the information handling system that is operable to allow a cache in a volatile memory to be flushed to a non-volatile memory when the alternating current input waveform is withdrawn.
