Can I wire 2 12v power supplies from a computer in series to get a 24v power supply? One of them is 20A and the other is 10A so if it is possible I'm sure I would have to be under the 10A correct?
thanks

I don't think there is an easy answer on this. If the power supply had true isolation on the dc side you should be able too. If one of them doesn't, you won't be able to. If you can, you should be able to get 10A. There are so many pc supplies out there all costs and quality, hard telling. If your game try it.

I wonder if there is a voltage doubler circuit that would handle 30 amps or so? That way you would hook the power supplies in parallel.
I'm not much of an electronics expert though so it's also a question.

Sure with BIG components, but your couldn't get doubled voltage with the same current rating. i.e. 30amps at 12V voltage doubled would be less than 15A. Not so sure the payback is there.

jderou,
connect a 10k resistor between GND of one of your supplies and +12V on the other. Measure the voltage over the resistor. If it is 0V then you are in luck, if it is 12V then it won't work.

Thanks for the advice, I'll try it tonight!
