Default PSU in class D amplifier

In an amplifier calse D is it necessary the same quantity of current of power supply that in an AB? It is a doubt that I have because theoretically a clase D has best efficiency that an AB and it does not lose so much power in the shape of heat

You require as much power as the amplifier produces plus about 15% if 90% efficient.
