As illustrated, however, energy storage devices 805, 810, 815 are shown as separate energy storage devices, providing power to only one or a subset of components of system 800. For example, energy storage device 805 is illustrated as providing power to a central processing unit comprising four individual processing cores. Energy storage device 810 is illustrated as providing power to a memory unit, a network unit, and an input/output unit. Energy storage device 815 is illustrated as providing power to the input/output and a graphics processor. It will be appreciated that the electrical connection providing power from the energy storage devices to another component may be switchably achieved, such as by using one or more transistors, relays, or other controllable switching circuits.
