Is there any difference between this two different type of powerbricks besides the watts? Will they cause the RROD to appeared if the wrong watt powerbrick is used? You see, I got me a used xbox 360 with the RROD problem. No accessories included, just the console. In addition, I purchased a used set of the AV cable and the powerbrick w/ cord in good conditions. The powerbrick is showing the 203 watt info. I heard that not all powerbricks works with all xbox 360's. Can this be true? Can this be the problem to the RROD?
