ok, i just ordered the fortron ax500a last nite. i read a lot of posts from these forums that all agreed this is a pretty darn good psu, especially for the price. now i'm reading a lot of posts [mostly about sli] that are saying to avoid dual 12v rails. i have no plans for sli at the moment [nor do i see it in the close future], but should i still be avoiding the dual 12v rails?
