Oh my god not again no the Gigabyte does not need or draw 450 watts its the cooler that can do up to 450 watts worth of HEAT its not power draw they are talking about

And you dont need more then 650-700 watts for GTX 770 SLI

it's oc'd 3930k, which is pretty much highest power draw cpu on the market iirc (hence 750-850w for simultaneous max cpu + gpu loads being comfortable)

My OC is very light, just the turbo at 4.0 instead of the default 3.8. But when the two cards will be at max, the CPU will only be at 10% tops, so it should be fine.

I am running 780 SLI on 850w PSU and an overclocked I7

you should be pretty fine with 850w PSU for 770 SLI
