Hello fellow weeders, I'm building a new grow cabinent and want to use a bunch of excess computer fans I have laying around. Rather than go get a bunch of transformers, I would like to use one of the excess computer power supplies I have laying around. Unfortunately, even if I jumper the power switch to the "on" position, they all need to be plugged into a motherboard to power up. Has anyone figured out how to solve this or know of a way around it that doesn't involce permanently placing a CPU power supply tester on it? Any and all info is greatly appreciated. Thanks much!
