At least one computer system receives power from a power system having a
maximum power output based on a nominal power consumption of the at least
one computer system. The power system is operable to detect an amount of
power consumed by the at least one computer system, and compare the power
consumption to a threshold based on the maximum power output of the power
supply. The power system is operable to place one or more components of
the at least one computer system in a lower-power state to reduce power
consumption in response to the amount of power consumed by the at least
one computer system exceeding the threshold.
