Default Power Supply ? - Amperage / Rail

1. This is the power supply that I have, Antec CP-850: http://www.antec.com/Believe_it/product.php?id=NzIw.

First Question: It has 4 12 volt rails with two of them at 22A and the other two are rated at 25A with all rails 5%. If all of the Amps are converted to Wattage, then it comes out to 1128 Watts. Now at the lowest (-5%) on all the amps, it comes out to 1071.6 Watts. Is the company practically saying that the Amps listed are the absolute maximum power the power supply can handle with Wattage?

Second Question: If a video card requires 42 Amps on a single rail (for ex: a GTX 580), would it be sufficient to combine two rails to power a 42 Amp video card that recommends 42 Amps on a single rail? The reason I ask, is because, the gaming series Antec PSU's max Amp on a rail is 40A. I am only experienced with Antec Power Supplies and BFG (what use to be) power supplies. So, I don't know what kind of power other companies are loading into their PSU's.

Thanks for any help / input!
