Another question for anyone. Is 33 amps on the 12v output enough? I am trying to think of any reason I am having such a hard time with this Q6600. My Powerstream is spec'd at 33 amps for the 12v. I am not sure if it has duel rails or not, can't remember. But it is the SLI model I do know that the 12v output is holding steady at 12.36. I am grasping at anything I can think of.
