That doesn't even matter in this case.

40 amps = 40 amps, no matter how many 12V rails you have. If you have multiple rails, you simply add the amps up.
Not really. Each rail can supply a maximum of 20A, but the total amperage of both the rails will be inferior to 40A.

= 2 x 20 amp rails doesn't equal 40 amps but closer to 36 amps.

That's pretty precise It all depends on how far the manufacturer is willing to bend the truth.

True true. Manufacters like Antec, Corsair, Cooler Master, and OCZ tend to be more honest about their figures because they've got a reputation to hold up.

I see. I was always under the impression you were supposed to add them all up.
