Dynamic converter control for efficient operation

Dynamically managing power consumption in a computer system having at least two parallel power converters in order to improve efficiency. A maximum power capacity for each of the power converters is determined and then power consumption of the computer system is monitored. If the power consumption of the computer system can be provided by less than all of the parallel power converters then one or more of the power converters is turned off, such that a reduced number of parallel power converters remains turned on. A reduced maximum power capacity of the reduced number of parallel power converters is determined and a power cap value is set for the computer system that is less than or equal to the reduced maximum power capacity. The computer system is throttled at the power cap to prevent power consumption of the computer system from exceeding the power cap value.
