I'm looking at upgrading my psu to allow and upgrade of a gtx 970.
What the benefits of having either and which one do you prefer and why?
Thanks everyone
Your Q is a little old and you have no doubt gone out and bought a new psu by now. But if it helps I have had several single 12v rail power supplies fail on me after a relatively short time and am certain that dual rail psu's over otherwise very similar spec running on identical hardware last longer!
