I have tried it on two PSU, the second a Thermaltake Toughpower. And when I say 'in the red' I mean that literally. The board changes text colour for high voltages, Ive tried upto 2V for northbridge and so on. Its not the operating voltages, this is 9 hours prime at 3.6GHz with a quad at 1.47v and its rock solid. Its just won't boot from standby unless the psu power is reset. You can see it restart itself, the other thing I don't trust is the FSB voltage overvolts itself without being set. Select 1.5v, goes to 1.8v. Somethings not right.
