A connector with a limited ampacity supplies a load which draws more current than the ampacity of the connector. A buck converter changes the power passing through the connector to a higher current at a lower voltage to energize the load.Alternatively, if the load is intermittent, the current passing through the connector may charge a large capacitor which is able to supply a larger current to the intermittent load. The capacitor may also be used to power a continuous load, such as a memory, during failure of a power supply feeding the connector.
