Since Tom has mentioned
ONLY 2 8pins. We can sorta workout the max power consumption. 8pins can provide up to 150w, while PCIe can provide 75w of juice, which means.
150+150+75=375w. Which is the maximum, considering 570 2way SLI uses ~400w it suggests Nvidia has either pulled out some sort of hat trick, or the card is gonna be underclocked and make all the Green team fanboys go
, while the Red team goes BOOOYEAH!!!!!!!!!!!!!!!!
EDIT: But looking at the brighter side, it shouldn't be hotter than the 6990.
