The Arctic Cooling Fusion 550R 550W PSU is an interesting unit. It has a few innovative ideas - mainly the fan on the outside of the box that adds to the curb appeal. It appears to be very stable in terms of voltage as well as ripple and noise. In fact, it's probably one of the most stable PSUs we've tested around here. You'd think that it would be a hands-down winner, but it does have a couple of issues. . .
