I bought this power supply from "xpit" and it was made by Revain. The delivery was fast and the packaging was good. The plug type was correct (203W) but after about 8 MINUTES of use (seriously) it smelled horribly like burnt electronics and the status LED turned red and stopped working forever. To say I am disappointed in the quality of this product would be an understatement. This is a VERY cheap copy of the original Microsoft power supply. Obviously the manufacturer has no quality control which I think could pose a hazard to your console or even cause a fire.
