That is recomended, but not esential for NF4 boards like this.
The ATX 2.0 spec's where developed for server applications well before the advent of of SLI motherboards. In a server environment dual rail power supplies are very usefull in supporting multiple hard drive arrays. The ATX 2.0 specs did not take into account the high power requirements of the motherboard when running 2 high end video cards.
Dual rail power supply should not be used on this board!! unless you can find one with 25a on the primary rail.
