At the end of this month I will be getting a second 6970 for crossfire and need to know if my current psu (Ultra X3 800-watt) will cut it.

Specs of the Ultra X3 800-watt:

Specs of my rig are in my signature. I'm using 11 fans in my rig in addition to what's in the sig. I used one of those PSU calculators and it told me I'd consume around 900 watts with a 90% load. However, I know how unreliable those psu calculators are.

If my current PSU isn't enough...do you think a Corsair AX850 would suffice or should I opt for an AX1200 instead.

AMD recommends a 550W to power a system with one 6970 in it, so that means a quality 650-750W power supply would be enough.

Edit: your PSU's +12V is 660W which means it's basically just a 700-750W power supply (except, it still has enough power).
So, I'd basically be cutting it really close then?

No, it has enough power. I'm just being a little judgmental about this PSU.
