I was wiring a fan up to put in my case either i crossed the ground and +12 or it was shorted inside when i powerd the pc up i smelled smoke and saw white smoke puffing out my psu i yanked power fast and looked at fan as you will see soon not much left of the power cable on it. I took the fan and left over wires out and decided to be brave and try to power and everything works fine the enermax didnt fry and it saved all my parts lol and probly saved me from a heartattack if i fried everything in my pc.
