nope, the cord is there so that if Foxlinks POS power supply just happens to short, the Power cord's fuse pops, thus saving your xbox, but not fixing the problem. If those two joints look really nasty, just re-heat them with a soldering iron, adding a little solder as well, but not too much. btw, if it DID fry the entire thing, PM me cauz I have one I'm selling.
