Some sort of fuse. There are resettable circuit board fuses that might work.

There are also tantalum capacitors that have built in fuses. Obviously they will not prevent the capacitor or power supply from failing, but they will create a graceful failure.

Good point. I guess the question for the OP is where will there be a short circuit?
