I believe they also do 500/600w versions. I wouldnt mind giving one of the higher wattage ones ago, to see if this efficiency & stability runs thru the whole range.
Yep, there are 500W and 600W versions. 500W retails for about $105 and the 600W for about $135 right now. Both boastin pretty high efficiency which is pretty cool... Strange that the 430W isn't listed on CM's US site...
