Basically, the card will suck the juice out of the PSU, and if the PSU can't handle it, well, it will minimize again. The best way to measure your 3.3v rail is to use a multimeter, much more acurate than any type of software, plus they are ~10 bux at a local hardware store.
I do have a great multimeter,and I can use it. I just need a quick heads-up on how much fluctuation there can be at the 3.3 pins (heck, at all three voltages) is tolerable, and when they should be taken. Under 'load' I only have software to sensor readings to trust (Speedfan, etc)...static readings, I am to take it is where we start then? I have 1.38, 11.62, 3.25 (all vdc) right at the moment--With only browser and speedfan running.
How much tolerance is acceptable--or is it smoothed in the 'good' PSU to precise voltages?
