I cant say that I've heard any unusual noise from the unit. Obviously the PSU testing equipment creates quite a bit of noise its self, but normally PSU's that make high pitched noises stand out above the low-pitched hum of the fans.
As for the single 12v rail, I can see where you're coming from. However I've not heard of any cases where a failure of a single rail PSU was any more catastrophic than a multi-rail PSU. At the end of the day 1200w is 1200w. Even if its split cleverly by OCP, it still has the potential to go wrong. Unless a PSU is physically split (different transformers etc) then it's naive to assume multi-rail is safer.
I did also get a gut feeling that the AX1200 was safer than a lot of other units I've tested before. It handled overloading extremely well and shut down gracefully without me wincing and expecting a *bang*. That is just a gut feeling though.
