PSU in my rig question

[King Icewind]

So I have the corsair 850tx and with my mobo I have the option to do 3 way SLI + Physx.

So aside from the the physx, how much bigger of a psu will I need or will this be enough(although I doubt it)? All of the video cards will be the same as the one in my sig.

And what about with Physx?

I've used many different calculators, which gave me mixed results. I just want to hear what everyone else has to say.

Thanks.

What card do you plan on using for PhysX? And do you plan on overclocking at all? Your TX850 will be enough for tri-SLI with GTX260s plus something like a 9800GT if you won't be overclocking anything. If you will be overclocking, I'd probably recommend a 1kW PSU depending on how high you plan on going.

I've done a little overclocking. Or more like my mobo did. It has a Dummy O.C. which brings it up to 3.3ghz. Otherwise I don't think that I will overclock anymore, unless for some reason 3.3ghz isn't enough

Im waiting for the new video cards to come out, since the price will drop. Sooo, does any one know when the knew video cards come out?
