In a multirail PSU each rail is limited by dedicated OCP. In a silgle rail PSU all rails are limited by one powerful OCP. So the overcurrent shutdown is less possible in case of single rail PSU. Also as far as I know a multirail PSU with OCP equal or less 20A per each rail have the only one advantage - accordance to EN-60950 safety standard (it's considered that burning etc is less possible with 240VA / 12V = 20A limit per each rail). But such PSUs are not suitable for building modern highend systems because of modern powerful PC components that can easily draw more than 20A from the one rail.

How are they limited then?
Why do they not exist anymore?
