Using a Benchtop PSU to heat wires? Answered
I modified a 300W ATX power supply that I got for $1 the other day to use as a benchtop power source, much the same way the people who have posted Instructables for this have done. I want to do some experimenting heating up wires, but I don't want to harm the PSU. I believe it has built-in short circuit protection, but I want to be safe anyways. I think that if I put in a high-wattage resistor in parallel with the heating wire, that might save the PSU. If I did this, what value resistor (ballpark range) would I need so that power would flow through the wire until it heated up too much (thus increasing resistance across it), causing the power to go through the resistor instead?
