i found out that for the atx psu specs, the second rail is always assigned to the cpu and the first one to the 24 pin mobo and molex,etc....

wouldn't dual rails be better for ocing since the cpu gets it own rail to take as much power from the psu as it needs? -more stability you know?

my crappy antec smart power 500 which has dual rails, when it crapped out, it only took a bit of my mobo (mobo works but doesn't read my temps correctly anymore) and hdd, but the test of my system stayed in tact.. so i would believe that chewy is right about multi rail psu's not taking out the whole system, which may help especcially if you have a expensive system...
