I read a guy mentioning on a system that he could not run two
Nvidia 660's on this power supplys. The rating is kinda iffy on NewEgg as it is. I jsut want to make sure it is good enough and it will run an SLI with two 670's. I also am overclocking my I7 to 4.5. Here is the card's link http://www.newegg.com/Product/Product.aspx?Item=N82E168....

What is the real difference between

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

and

http://www.newegg.com/Product/Product.aspx?Item=17-139-...

the only difference I see is the lack of crossfire on the second one, which is negligable since I do not use ATI

here is my system

Hi - The TX series is a step up from the CX(budget) series. I suggest if you are purchasing a PSU, whichever brand
you choose, always try to get above the budget/opening price point series.

Yes - You will be able to SLI with the unit you linked, it also has 4 pci-e connectors which you
will need to SLI if the 670's each take two, which I haven't dbl checked.

Tom

Hi again - Yes most 670's require 2 pci-e connectors each
