Abstract
An information handling system includes active and standby power supplies and a power assist unit. The power supplies provide power to a power rail. The standby power supply supplies current to the power rail when a current demanded by a load is greater than a proportion of a maximum current demand, and is off when the current demand is less than the proportion. The power assist unit is coupled to the power rail and includes a power storage element, a converter coupled to the power storage element and to the power rail, and a controller. The controller receives a current level indication that indicates the current demanded by the load, and in response to the current level indication indicating that the current demand peaks to greater than the proportion of the maximum current demand, directs the converter to provide power from the power storage element to the power rail to prevent the second power supply unit from turning on.
