from www.cyberguys.com or computergeeks.com. Radio Shack doesn't have as complete a stock of computer repair parts.
The capacitors in the supply can hold a charge for quite a while be careful. They can jolt you a little but melt a screwdriver tip in you short one to ground.
I have a Gateway pc in a microatx case. The fan built into the power supply is going bad. I was wondering if I can just replace the fan or if I have to replace the whole supply? If I found a fan...say at radio shack or comp usa with the same demensions and specs couldn't I just cut the two wires to the fan and replace it or is there more to it than that?
