what are dual 12v rails. i know that some powersupplies have 1 12v rail and some have 2. are powersupplies with dual 12v rails more powerful. i have seen 500w antec powersupplies with dual 12v rails with 19amps on each rail which totals to 38 amps. but i have a 500w powersupply that only has one 12v rail but it has 38amps on one rail. so do both powersupplies have the same amount of power. and if both powersupplies have the same amount of power, whats the point of dual 12v rails.
