I am running a dual rail, and it has been awesome. Now, that said, I have not OC's yet, as I am relatively new to OC's and want to replace my ram first.
I did a lot of research on the Dual Rail thing, and because of the SLI configuration and the VC's needing a steady reliable source of power, I chose this one (in my Sig).
My power Sup has been extremely useful in preventing the shorts that could have occured, but DIDNT because the PSU found them and turned off first. (Bad Floppy). The stats are pretty good and according to the specs in the book it should support whatever I decide to do with the OC'ing when the time arrives. Of course, it was a little expensive.
