Beast.

I was lucky enough to see the results prior to it going live.

It is truly epic. With a price-tag to match. Ouch.

But clearly if you want the best...

I dont think its too bad, the aging HX1000w is still selling for £190, so for all that power and gold efficiency then I dont think its too bad. Just found it at scan for £246 now too.....

Am I the only one who finds 6 pcie connectors lacking? Corsair's own 850W unit has 6, which has 30% less power. Antec's 1200W has 8 and the OC edition has 12!

OMG look at the RIPPLE! (Or lack there-of). Awesome stuff! Me want!

Have you noticed any electronics noise?

And, well, to the danger of 100A, we don't need to say anything, do we?

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.
