Marvell chip claims to make PCs more energy efficient

Filed under: ,

Mark this down as a little out there, but a new Marvell chip claims to improve the efficiency of desktop and laptop power supplies by determining and then optimizing the amount of energy each particular application needs. Named a “power factor correction controller,” the chip enables computers to comply with new Energy Star guidelines that require computers to use at least 80 percent of the energy supplied to power them. It’s not the only chip out there that claims to improve efficiency using this method, although Marvell has already started producing the chips with the aim of hitting full volume production in Q1 2008, and seeing them in PCs thereafter.
