[kayawish24]

i want to know that i have corsair TX850 850watts PSU in which 12V is 70A and its only one 12V rail so the question is can i put Three 8800 gtx cards on it to have Tri SLI? or i have to go for 1000 PSU??????

I think Anandtech ran a tri-SLIed setup with 3 8800 GTXs on a 860 watt PCP&C. You may be able to get away with it.

However, Id buy the 1kw Corsair myself just to be safe.
