12, or 9 volt adapters just like you have for phone chargers, just snip off the connector and the pc's connector and wire them together.
works like a charm :thumbsup:
Completely Stoned Reviewed by Completely Stoned on . New Growbox I'm going to use a new growbox that is a couple of old toyboxes. I am fine for lights and I do have CPU fans, but I don't have an old pc to wire them too. Is there a powersupply that I can connect my fans to without needing a motherboard or anything? Rating: 5
