Actually there should not be any cross loading problems by design here as this PSU uses DC/DC converters to regulate +5V and +3.3V independently of +12V.

I suspect that the problem might rather be related to the voltage regulation on the mainboard.
It's good to know however that the Power Supply Idle Control option is part of an AGESA update.
