Tagan SuperRock 680W TG680-U33II
 

The Tagan SuperRock 680W is a great power supply for budget aware users who are looking for a cost effective way to power their system. With 680W it should be good for almost everything you can throw at it. During our testing we found out that the PSU is running very quiet which makes it a good candidate for a silent media PC system, too.
