1. A method of estimating peak power usage of a computing system having a CPU, comprising:

  • identifying a computing system among a plurality of computing systems installed in a data center;

    determining a plurality of components in the computing system;

    determining a peak power usage value for each component of the plurality of components as the computing system is operating at an operating condition that comprises an application being performed by the computing system;

    adding the peak power usage value for each component of the plurality of components together to result in an actual peak power value;

    based on the resulting actual peak power value, aggregating actual peak power draws of the plurality of computing systems to determine an actual peak power draw of the data center that comprises the plurality of computing systems;

    determining that the actual peak power draw of the data center is less than a sum of a maximum rated power draw of each of the plurality of computing systems;

    based on the determination, deploying an additional plurality of the computing systems in the data center, wherein a sum of the maximum rated power draw of each of the plurality and additional plurality of computing systems is greater than a design power capacity of the data center;

    determining a design power density of the data center based on the maximum rated power draw of each of the plurality and additional plurality of computing systems;

    determining an average power density of the data center based on the aggregated actual peak power draws of each of the plurality and additional plurality of computing systems; and

    determining an oversubscription ratio of the data center based on a ratio of the design power density to the average power density for the plurality and additional plurality of computing systems.
