1. A method of controlling power supplies in an information handling system (IHS), comprising:
- receiving a power request from a first electrical device in the IHS, the IHS having a number of operating power supplies;
determining if there is sufficient power to satisfy the power request;
determining an excess power supplied to the IHS, wherein the excess power is the difference between an amount of power allocated to a plurality of electrical devices in the IHS compared to an amount of power consumed by the plurality of electrical devices by calculating an average power consumption of each device over a time period and multiplying the average power consumption by a service factor; and
providing power to the first electrical device using only the number of operating power supplies if the excess power can satisfy the power request.

8. An information handling system (IHS), comprising:
-
a plurality of electrical devices; a number of operating power supplies electrically coupled to the plurality of electrical devices; a chassis management controller coupled to the plurality of electrical devices and the number of operating power supplies, whereupon receiving a power request from a requesting device, the chassis management controller is configured to; determine if there is sufficient power to satisfy the power request; determine an excess power supplied to the plurality of electrical devices, wherein the excess power is the difference between an amount of power allocated to the plurality of electrical devices compared to an amount of power consumed by the plurality of electrical devices multiplied by a service factor; and direct only the number of operating power supplies to provide power to the requesting device if the excess power can satisfy the power request. - View Dependent Claims (9, 10, 12, 13, 14)
