Hi, I was wondering that when companies advertise that a power supply have multiple rails, how do you know which modular/cable connection is on which rail. They never label it at the back of the PSU. I personally have the antec TruePower Quattro 1000w power supply and the only difference I see is that some modular PCI-e connections have red modular connection instead of black. This has been bugging me for a long time and any help would be appreciated.
