I keep seeing people post about needing different power supplies for red and green GT but I am still not sure why they are not interchangeable. From what I can see, the green board just needs 2 12v connectors plugged into it and 1 into the hard drive. I am sitting next to a couple power supplies I just yanked from a couple old computers that have the same connectors. Are they usable for a green board?
 
Maybe, sometimes the older green boards will pull the 5V rail down to 4.9 and since it has no adjustment knob on it you will always get a voltage low warning and the game will never boot.

Sometimes it does work though. I currrently have a red board BBH2 and a Green GT Complete running at the same time in my GT cab. I just have to flip the jamma harness (have a 2-way jamma switch and now also a perfect solutions switcher I haven't installed yet).
 
It looks like this won't be an issue for me after all. I just bought a GT Complete on ebay and talked the guy into selling me the power supply (that he wasn't planning on including) for only another $20 more. I am still curious though. Is there any possibility of damaging the PCB if I were to try a computer power supply, just to see if it works, in the name of science...sort of?
