imac--->ATX Questions - 07/18/05 04:50 AM

I am working on re-casing my tray loading imac into a PC case, I have almost finished but have become a little hung up on the wiring. I know there are a few different solutions for powering the computer, and I have decided to go with the pinouts and soft power coverter from http://www.radiomods.co.nz/imactoatxconversion/index.html. I am having a littl problem with the soft power though, I do not know which way to solder the transistor, The 3 pins are collector, base, and emitter. I am guessing this means that the imac line connects the the emmitter, the ground is the base and the PC is the collector. Can anyone on here look at his diagram and tell me if I am right, worong or have no Idea at all what I am doing? Any help would be greatly appretiated.

Assuming both your diagram, and the transistor itself follow the usual conventions, you have an NPN transistor here. The iMac (brown) should connect to the base, the +5V/ATX to the collector, and the ground to the emitter.

Sounds like a tight mod you have going. I look forward to seeing it when its finished. Just remember to BE CREATIVE! I would love to see a mod guide with all of the electirical work, that is something that can be scary to most newb modders. Good luck.
