Using PC Power Supply for Fans

Well I am very confused at how to use it to get the fans going. I have a power supply I stripped from an old computer. I have like 3 fans, but im not sure how to Get the to turn on. I have one connected to see if I can get them going but so far its not looking good. I have looked all over for guides specifically for modding it to turn on when I plug it in but no luck.

Use a cell phone charger.Im sure it will run 2.But not sure about 3?I have 2 running off of 1 charger thats also plugged into my timer to work w/lights.Good luck.

Well I used my power supply, Thanks to Toastedfox I used the paper clip trick, now the supply is working I just have to find out how to put another fan on it.

The good thing about using a psu from a computer is it can run multiple fans safely. A charger is just a charger, make sure it is rated for the current of the fan(s) your using. I am using a small 150w PSU. The 12v part is rated at 42watts. Then you can hook lots of ans up it paralel. A 3" fan is 2 or 3 watts. So you could hook up a dozen or so fans. Hook that green wire along with a black one to a switch and your set.
