    Somewhat over-voltaged by the looks of them. Had that happen to an old Masuda or similar TV with my head right over the top of the board once. Scared the craappp out of me..

    I have replaced the 2 x 2200uf and the 220uf and ordered a new fan

    sooooo it seems the fan fails first, then the power supply failed due to overheating..........

    Not being familiar with your particular type of power supply, it's hard to comment. But I'd be checking all the electros in the power supply for high ESR. Also be checking all the semi's in the power supply, and if it was a massive overvoltage on the output of the power supply (which is what usually causes such catastophic failure of the electros) there is a possibility it has taken out other components further down stream.
    As for the cause of the original failure..?? maybe as simple as a couple of small electro caps in the front of the power supply dried out.

    That's somewhat nasty

    I'd be replacing the supply after verifying that the Xbox itself didn't suffer any damage.
    A clone supply can be had for $24 from a local supplier. I got one of these a while back and the only criticism I have is the fan's a bit noisy.



    These supplies are fairly simple with only 2 outputs, 5V standby and 12V main supply. If there was a serious overvoltage on the 5V output the 3.3V regulator in the xbox will likely be toast, if not more than that. Overvoltage on the 12V output could do some serious damage (mosfets caps etc) in the console.

    Those coils are the capacitor plates which are coiled around each other and separated by electrolyte soaked matting (cat's fur ). The electrolyte is usually soaked into what looks like fibreglass matting between the plates.
