Best PS for Dual 260's

I'm using a EVGA 122-CK-NF68-A1 LGA 775 NVIDIA nForce 680i mobo and have 2 GTX 260 that I'd like to both run at the same time.

Using Intel Core 2 Quad Q6600 Kentsfield 2.4GHz
4GB worth of CORSAIR Dominator CM2X1024-8500C5D

Case is this one here and the PS opening is 5.9" x 3.4"

From the list here, http://www.slizone.com/object/slizone_build_psu.html
what would be the best option with the size needing to be

Looks like I need to go with the Antec HCG-900 or the Antec TP750 so that it fits. Possibly the Corsair TX850, as all of these are 5.9" x 3.4"

Which of the 3 should I get, and if there is a better option, what would it be?

Any QUALTY 750W model will easily be enough.

Of those listed I would buy the HCGC 900W for the price only. You dont remotely need that amount of power but...

personally i would get http://www.newegg.com/Product/Product.aspx?Item=N82E16817139021
whihc will pervide adaqite wattage and high enough amps to push enough power to your computer and is a little cheaper then the listed few

Agreed. Solid choice!
