I am running an I7 4770k CPU with and Asus Maximus VI Hero motherboard. And i have 1 256gb SSD and 1 1tb Hard drive and, an H100 hydro cooler. I am using a GTX 780 ACX graphics card and its all being powered by a Corsair AX850 and i have no problem with power or anything like that. My question is, I am going to buy another GTX 780 ACX and I'm not sure if I need a bigger PSU or if the 850 is enough to power everything I have plus another 780. I have seen videos on YouTube from Asus's channel and they have 2 780's power by an 850 PSU. So do I need more power or is an 850 enough power to run my system plus 2 780's in SLI?

The 850w will do , but I'd go for some extra headroom.
