Yes, like I said I did do my homework with this one as the PSU is kind of vital. The single 12V rail delivers 50A. And I saw a thorough test that showed that it really does deliver what it says on the tin. See the specs here, and the test I read is here. (The link is straight to page five of the test which is where the numbers are.) Really, I'm not too worried about this one.
