Arctic Cooling Fusion 550RF PSU Review @ BayReviews.com

"When shopping for a new power supply unit (PSU), most people just look at the advertised watts and base their entire purchase on that alone. That's fine for most average users but when you get into more power hungry systems, you want to have the best and most stable power supply that can provide consistent and stable power at all times. This may require investing in a higher quality power supply."
