Hey everyone, I just upgraded to a 780 and am debating with the idea of getting a second. I was not originally planning on it so I have a xfx pro 850w power supply. Which is gold rated. I also have a I5 3570k overlooked to 4.6 ghz. I might be watercooling in the future so add in a pump and small amounts of voltage for more fans. I'm thinking I might have to upgrade if I wanted to sli. However I've been looking around and everyone seems to have a different opinion.

Thanks guys, and merry christmas!

gtx 780 requires 250W, so 2 780 will be 500W

another 340W for the rest of the components is more than sufficient. (the psu can provide 840w on the 12v rail)

you will be good.

3.Difference (GPU load) = 488W
4.Add average IDLE wattage ~20W
5.Subjective obtained GPU power consumption = ~ 508 Watts

GeForce GTX 780 2-way SLI - On your average system the cards require you to have a 750/800 Watt power supply unit as minimum.

So you will be fine. Don't worry. And the PSU is solid.
