Re:GeForce 9600 GT, power supply questions around 12V rails? - 2008/06/02 03:13
Well it is true that they can give 20Amps each, but that's the maximum they can run individually. If you tried putting a 40Amps load on the 12V rails you would cause an overcurrent trip to occur really fast because the unit would not be able to provide that much power on the combined 12V rails. Both of the rails draw from the same source, which has its own current limit that can't be exceeded. Manufacturers list the individual current limits for the two 12V rails to make the power supply appear to provide more power than it really can.
