Yes - where you buy one depends on how much current you need. If it is low current you can pick one up at Radioshack, if you need high current you'll need to find a place that sells power supplies.

What EXACTLY do you want to power with it?

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Is it an AT or ATX supply? If it is an ATX supply, grounding the green wire will turn the supply on. Breaking that connection will turn the supply off.
