I have an original xbox 360 and it needs the 203 power supply. I order this one as it was advertised as a 203. When I got it the sticker said it was a 175. Since the plug that plugs into the xbox is very specific to the 203 I looked at it closely. The plug was a 203 plug. So I used it on my xbox and it worked fine. So I guess it was incorrectly labeled at the factory.
