Is the Corsair 850watt Single Rail PSU enough for Tri-SLI GTX 260's 216 core?

Which 850W Corsair?

I would recommend 2x GTX275 instead.

I think he's referring to the "new" modualr 850W Corsair PSU I think.

The PSU size calculator doesn't provide for 3-way SLI, but doing some extrapolating (another 117W for card #3), I got only 557W. That makes some assumptions, of course, including a CPU overclock and a total of 4 standard 120mm fans.
In any case, the answer appears to be a clear "Yes."

or the TX850.
Either way they should both be similar in performance.

Yes it has enough power do run the 3 x SLI GTX 260s. However, as noted and if you don't already own the 260s, 2 x 275s would a better option all around.
