Difference between Rail and Dual Rail?

[Ghostay]

The Corsair RMI has a rail feature where it can be dual or single, what does this mean and when would it be useful?

 

Thanks.

It's basically marketing noise, its allows the PSU maker to make a more stable output without the need of as thick of wiring (which allows for more amps), or as much quality of power control, it's pretty much standard at this point for PSUs so it means nothing (that psu is good though btw but usually expensive)

Ok, thanks!

Well usually if a PSU has multiple rails then for example, you have a dual rail 850w psu with 70amps, since it has two rails, each rail would have the capacity of 425w with 35amps each where as if it was a single rail 850w psu with 70amps then the single rail would have the full capacity of 850w and 70amps.

 

The single rail is best to leverage every single watt from the PSU where as a multi rail psu would allow the use thinner wires while still retaining the same quality of power.
