I'm looking to upgrade from my GTX 780 3GB SC, to 2 GTX 970s SLI, but I'm not sure if my current PSU will handle it or if I should upgrade the PSU as well. I current have a Corsair 750TX V2, and I have checked multiple different wattage calculators with results ranging from 600w to 1000w. So im not sure what is accurate here. Would the 750w be ok or is that not enough wattage? If I upgrade the PSU, I would go with the EVGA SuperNOVA 1000 P2.
