An exemplary power manager is adapted to supply power from a power supply to a first component of a gaming machine. The first component consumes a larger amount of current during a second time interval than during a first time interval, where the first component alternates between the first and second time intervals during operation. A rechargeable energy storage device is used to supply a substantial portion of the current to the first component during the second time interval from energy stored in the energy storage device prior to the start of the second time interval. This causes the current supplied from the power supply to the power manager during the second time interval to be less than the total current required by the first component during the second time interval and thus reduces the peak current load of the power supply during the second time interval.
