As far as i know, yes. I think each card take up around 250? Not 100% sure though.
EDIT: Crossfire with them takes about 600W
I was reading Crossfired they take 442w roughly. Idk how much the system itself needs though.
I believe that it should, but it would be best if you link the good fellows with more knowledge your current computer specs and which 6970s you want to crossfire.
I believe it should be able to, but more info would be helpful. PC specs, do you overclock your CPU, plan on OCing your GPUs, do any Folding@Home, etc?
Edit: Beaten to the punch
Cooler: CPU COOL NOCTUA|NH-D14 R 1
Video Card: VGA XFX|HD-697A-CNFC HD6970 2GB
Memory: 4G|GSKILL F3-12800CL9S-4GBRL X 2
PSU: CORSAIR| CMPSU-750HX 750W
Processor: INTEL|CORE I7 2600K 3.4G 8M
MoBo: ASUS|P8Z68-V PRO Z68 LGA1155
Hard drive: 1T|WD 7K 32M SATAIII WD10EALX
Haven't overlocked yet, was open to the idea, but nothing major.

With a 650W PSU its fine with one card a I5 OC + watercooler +9 fans and all the other usual thing (3 HDD) with 6950 OC higher than any 6970 (more power needed) I am pretty confident that a 850W PSU would be way enough.
AnandTech GPU Power Consumption
This is measured at the wall (so take off ~10-20% for PSU efficiency) for a full system, including IIRC an overclocked i7-950 @ 3.8GHz, so this is pretty representative of what you'll be pulling with an overclocked 2600K. This is also with FurMark running, a GPU power hog... with Crysis it goes down another 40 watts.
Your 850W is fine. My 650W would be fine, really.
Super casual.
