What size PSU should I buy?

[Guest]

Right now I'm buying a nice setup for my computer, and I'm not sure what PSU I should buy as I'm seeing variable ideas about different power supplies.

Setup (still ordering):
~i5 2500k
~7950 CF (waiting for these to eventually come out)
~128GB Crucial SSD
~Corsair Vengeance 4x4GB RAM @1600
~Asus P8Z68-V/Gen3 Mobo
~1TB HDD
~All in a Raven RV-02E
~Windows 7 64bit HP

Will eventually water cool both GPU's and the CPU with a 180x2 Rad and about another 240mm Rad.

Looking roughly for a 800-900w PSU, and modular. Anybody have any ideas? Trying not to spend over $150...

There is a PSU calculator here, that could help you. Buy a quality PSU, at least 80% efficient Bronze, like Corsair, Power PC and Cooling, Antec. Please read the reviews before you buy - newegg has extensive customer reviews of the products it sells.

I try not to base my decision on the reviews because a large chunk of bad reviews most likely come from user error because the idiots don't know how to install hardware into a computer >.<

Also, would the single 12v+ rail on the XFX be enough?

That XFX Davcon recommended is a very high quality power supply and would have no problem running 2 x 7950s.

This list is not perfect but in general is correct.
