The World's Tiniest Power Supply Unit
An anonymous reader writes "This year at CES members of the press got to grab a glimpse of the world's tiniest power supply. Well actually it is the world's tiniest 12V snap-in ATX DC-to-DC power supply, but you get the idea. This unit produces 120W of power and is about the size of two AA batteries. It is specifically designed for use with Mini-ITX motherboards, but can be used in many other applications."
So if I have a 480W power supply in my PC, could I somehow replace it with 4 of these? Since there's no fan, would it be quieter? Where do you get one of those bricks to convert from AC to DC, and how big/noisy are they?
