One 12v rail or Two with a PSU?

[Bitpiece]

I can't seem to get a definitive answer from my research as to whether it is better to go with a PSU that has one big 12v rail or one that has two (this is for running SLI).

Basically I'm thinking of getting the PC Power & Cooling Silencer 750 Quad-SLi PCI-E 750W Power Supply. I've heard some places give it rave reviews for its one 12v rail for SLI usage.


Opinions & expertise please!!!

Thanks for the welcome and the advice. I guess 1 or 2 rails doesn't matter v. much: just watts, decent make and warranty.

I will check out the corsair which I wasn't aware of or considering.
