1. A method comprising:
determining, by a computing device, a total power supply capacity comprising a sum of a plurality of supply capacities respectively corresponding to a plurality of power supplies serving a plurality of components;
determining a load value corresponding to the plurality of components; and
powering down a number of the plurality of power supplies, the number comprising a value that causes a remaining number of the plurality of power supplies serving the plurality of components to operate within an efficiency range, wherein powering down the number of the plurality of power supplies comprises:
determining a current efficiency comprising the load value corresponding to the plurality of components divided by the total power supply capacity respectively corresponding to the plurality of power supplies serving the plurality of components;
determining that the current efficiency is not in the efficiency range;
powering down a first power supply of the plurality of power supplies;
determining, after powering down the first power supply, the current efficiency comprising the load value corresponding to the plurality of components divided by the total power supply capacity respectively corresponding to the remaining number of the plurality of power supplies serving the plurality of components; and
determining, after powering down the first power supply, that the current efficiency is in the efficiency range.
