Typically, one +12v rail goes to the motherboard (ATX/SSI, 4pin +12, 8pin +12), and the other rail covers everything else...including the standard 4pin molex, SATA power, and any SLI power connectors. Unfortunately, the dual rail system was developed before SLI became a reality, and is a piss poor design when SLI is considered.
But if the average motherboard only uses 0.4A on the 12V line, what else is powered by the motherboard rail? Devices directly attached (USB, PCI, AGP, mouse and keyboard?)
