PCIe on the second rail and everything else on the first rail. I haven't seen that in a while. I'll check to see whether it's actually split up like that or not in the Dissection section.

There's some creative math going on with the 12 rails, 45 amps of 12v is 540w and 65 amps of 12v is 780w. If you add the two together you get 1320w, which is the same as two 660w rails. Of course either way you look at it you're over the 1275w unit limit. Not really sure what's up with that. The PSU label itself has the wattages calculated correctly.
Last chart, finally, is the protection limit chart:

|
|

|
I'm assuming that the 12v rail limit is for both combined, it doesn't specifically state either way.
That was intense, and that isn't all the data from Thermaltake.com either! If you're curious head on over there and check it out.
Next, lets take a look at the box and the PSU itself.
