A method for providing stable and reliable power to electronic devices is disclosed. In one embodiment, such a method includes providing a backplane having several power supplies coupled thereto. The method further provides connectors to connect multiple power-consuming devices, such as storage drives, expansion cards, memory expansion cards, or the like, to the backplane. In certain embodiments, the backplane provides a data transfer path and shared power distribution to the power-consuming devices. In the event a power supply is electrically decoupled from the backplane, the method enables a supplemental power-supplying device to supply power to the backplane by way of one of the connectors. A corresponding system is also disclosed.
