Hey bitcoiners, I've got a bit of a problem here and was hoping you could assist me.  I'm planning on upgrading my single Nvidia GTX580 to 4 (yes four) AMD 6970's in my primary rig.  Now, the problem is, my power supply, while rock solid, is only 850W  and with a solid state, a hard drive, 12GB of ram, an i7 970, and an asus rampage extreme all in there, newegg's Calculator told me, very clearcut, that i should have 1650W... wait, what?  1650W?   they dont even come that big, so i'm turning to you miners, what the heck do i do?  do i stick with my 850W power supply and buy like 2 supplementary PSU's @ 450W each to power my gpu's?  I'm at a loss here and welcome your input.


Cheers!
