The EX[34]200's do seem to have a lot more reserves when you pull power
than most kit. I actually wouldn't be surprised if you could manage to
do this, although doing it without crashing the cpu or forwarding chips
is a bit less likely.

If course if you want to do this the power supply has already failed
making this an academic concept only.
