New Power Supplies Could Save $3 Billion / Yr
What on Earth could save $3 billion in electric bills every year? More efficient PC power supplies!
Okay, so it's not the most fun solution, but it definitely is a no-brainer when current power supplies lose up to half their electricity as heat when converting AC to DC. This is why the newest Energy Star requirements say power supplies have to use at least 80 percent of the power going in. To capitalize on the new rules, a company named Marvell has released chips that can figure out precisely how much power your computer needs at any given time.
These chips can be put into new power supplies and help regulate their electricity use. Good news, especially when the EPA says there are more than 10 billion power supplies sucking down electricity. The chips are set to be produced in early 2008, so look out for them if you're going to be upgrading in the new year.
