am i right to assume that since w = v*a, a total system power consumption of 446w under furmark (according to the link above) divided by 12v would give 37.17a, exactly what EVGA requires. According to http://www.techpowerup.com/reviews/ASUS/GeForce_GTX_570/25.html,
the card itself could use up to 298w, (24.9a), more than a single rail on my psu can supply.
am i completely wrong with those? how can i make sure that the system is balanced over all 5 rails. does it do it automatically?
