Hi Guys.
I think I am way over my head with this one!
I have:
Asus M5A99X EVO Motherboard
700W Cool Master Silent Pro PSU
AMD FX-8120 Clocked at 4.500GHz
Corsair H100 with 4 fans.
16Gb Corsair Vengeance RAM
Two 12V Corsair Tower fans
Two Radeon Sapphire 6900 Series Graphics Cards

Do I have enough power from my PSU to run these?
And how can I power both Graphics Cards when they both need 2×6pins from the PSU? I have looked at the PSU and there is only one for the Graphics Card. Do I need a splitter cable or a bigger PSU?

Your shared wisdom will be very much appreciated ;-)
