The rail is implemented on the PSU, not in the cable. You may have a rail for each PSU connection (in a modular PSU). It depends on how its implemented.

As noted in the link to jonnyguru, multiple rails is for safety. It prevents any single 12V rail from having too much current. You DO NOT want 1000W (83A) of power going down a single connector!! Multiple rails prevent that.
i see, then if i get this right, is possible that a cheap psu has a single rail (pcb goldy line thinigies) powering multiple (12v) connectors, leading to an overload.

if i get this right, the multiple rails COULD mean that in the aforementioned example, 6+2 connectors have a rail for each one of them, right?

makes me wonder, however, why would theres even a selector for single or multi, seems like multi is the best way to go, no?
