"Turn off the fridge, Bob, the sun is beginning to fade" That might be the very shouts of the general populous as ecological crisis flourishes over the next few years; most experts worth their farthing would agree that we need to turn our wasteful ways around.
A damned good way of doing that might be chucking out the power-hungry PSU in our computer and replacing it with one that merely sips at the AC juice. That's where ColdWatt steps in.
Their magnetics-based technology reduces power consumption by 30-percent through far less of the electricity being wasted as heat; 45-percent less, in fact. So far, they're making PSUs for servers, hoping to tempt in network admins with the promise of $50,000 a year savings for a data centre running 400 servers.
Apparently AMD have expressed interest, and Intel showed demo models last year that used ColdWatt technology.
