Dual 12V?

[stonedwaldo420]

I am looking to buy a power supply for a DFI SLI-DR based rig, so it will probably need lots of amps on the 12V rail. What is better, a single 30A 12V rail, or two 15A? or is there no difference?
My answer is probably already somewhere on the forums, but I haven’t been able to find it in either the stickys or searching the forum.

You will probably eant an ATX12v2.0 PSU for load isolation and for future copatibility.

aaah, so all of the ATX12v2.0 supplies have dual 12V?
That would make a lot of sense since it is 2.0.
Thanks for the advice. that really narrows down my choices.
