Here's a question for you.

The Mac Mini (and most if not all motherboards) use switchers to do their DC-DC conversion. (An example would be generating a CPU core voltage around 1.0 volts from a 12 volt bus.) Switchers work by disconnecting the source supply from the load (e.g. through a flyback circuit) for significant portions of the switching cycle.

Given that the load is disconnected from the source much of the time, why is system performance determined by the "speed" of the regulation of the source power supply?
