It's the same as in this review: http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=163

I have a feeling that since each "rail" is individually listed as 25A (which would mean 1200W output if true for each rail), but the max load on all +12V is 56A, that any concerns are unwarranted, any distinction is just the current rating of the molex connectors and wires.
