Claim 8:
9. A system comprising:
a memory storage; and
a processing unit coupled to the memory storage, wherein the processing unit is operative to:
determine a total power supply capacity comprising a sum of a plurality of power supply capacities respectively corresponding to a plurality of power supplies serving a plurality of components;
determine a total system power requirement comprising a sum of a plurality of power requirements respectively corresponding to the plurality of components;
determine a need to add a new component to the plurality of components, the processing unit being operative to determine the need to add the new component to the plurality of components comprises the processing unit being operative to determine that a temperature rise in an area on the chassis by a fan row, and wherein the new component comprises the fan row;
adding a new power requirement to the total system power requirement, the new power requirement corresponding to the new component;
determine that the total power supply capacity is less than the total system power requirement;
power up a new power supply in the plurality of power supplies serving the plurality of components in response to determining that the total power supply capacity is less than the total system power requirement; and
power up the new component in the plurality of components in response to powering up the new power supply.
