What is the 12V rail's current rating on this power supply? Both Antec's website and Newegg show it to be 24A but I recently went to a local computer store and saw something different. They had a whole bunch of retail Antecs there and the small table on the True550's box actually showed 30A on 12V (this was the normal ATX one, not the 24-pin server version). So does this PSU do 24A or 30A? Are there two different versions of it or something like that? There was also a Truecontrol 550 there, which I think is the same thing with a drive bay fan controller, but its box showed 24A on the 12V line, so I'm sort of confused now.
