Hello, I just stumbled upon an old PC power supply. I thought it would be a good idea to reuse it. I am thinking making out of it a simple voltage source, as it is already voltage source. Can somebody explain me how can I safely get that voltage from those hanging cables that go into HDDs, CD roms etc. And would anything special happen if I accidentally short circuit that output(12 V DC or so). Voltage source is pretty old, it has 175 W and a bunch of other technical stuff written on it. Peak amperage, voltage etc. If you are interested I can write that down too.
