Arctic Cooling Fusion 550RF is a 500 W continuous 550 W peak power supply from Arctic Cooling with an external 80-mm fluid dynamic bearing fan. To start off, we must say that we were really disappointed with the name chosen by Arctic Cooling for this product. 550RF leads you to believe that this is a 550 W product, when in fact it is a 500 W power supply. The 550 W on the name is the peak power, which according to the manufacturer can be sustained for only ONE SECOND. This kind of gimmick is typically used by low-end manufacturers and we wouldn't expect this from a Swiss-based company. But besides that, is Fusion 550RF a good product?
