I had the same thought last time mine crapped out. Instead of doing the
science as you propose, I replaced with an over capacity wall wart (3-4A I
think) and that's the one that just failed.
I don't know enough about PS electronics to say if anything other than
over-drawing current could stress the PS.
It also makes me worry about getting power from the USB of the Myth box.
It's one thing to kill a $15 wall wart and another to kill a $100 PC power
