HX1000i question

[Ramses]

I keep reading that one can enable multi-rail mode in Corsair Link, but none of the several pretty through reviews say word one about this being anything but a single rail PSU.
What's the deal? It doesn't matter either way to me but I'd like to know.

Single rail (per reviewers) mean that there is only one source of 12v voltage. Multiple "rails" are created by having individual circuits from the 12v source have their own OCP unit.

http://www.overclock.net/t/761202/single-rail-vs-multi-rail-explained This explains it farely well. In the case of the HX1000i, the OCP per rail is software based rather than hardware based.

The software vs hardware based bit was confusing me.
Way happy with this power supply though..

If it's hardware based, you cannot change the values at which it would shut down. Since it is hardware based, it will not fail unless one of its components fail.

If it's software based, you can change it. Software can sometimes be buggy and unreliable.

It's more complicated than that, but from an end-user standpoint, that's really all that matters.
