GS logic board power connector as follows:


7   -5V
6   -12V
5   +12V
4   +5V
3   No connection
2   GND
1   GND

The pins are numbered as above when you are sitting in front of the
computer with pin 7 is closest to the back of the motherboard.

A standard PC power supply should work just fine.  It is better
than the "proper" power supply (more amps).  Steve Buggie sells
modified PC power supplies for the GS.
