Actually, benching is the scenario when the most power is drawn.

2600K @ <1.45v ~170W(Prime95, Large FFT), and <150W in anything else
6970 @ <1.2v ~270W(Furmark), and <230W in anything else
everything else <70W

^An AX750 will easily deal with this 'worst case scenario'

That would be true if I intended to keep the exact same system for the next four years or so, but things change so I would appreciate the extra headroom for future changes.

Ordered the Corsair AX 850w in the end, thanks for all the suggestions.

Good choice. I have one myself too, I had AX650 but blew up. I sent it back and grabbed AX850 instead. One more chance for Corsair. It is very quiet, no coil whine at all, hope it will last some time to come.

That's true, they are both Seasonic models, but the Seasonic versions has less ripples and a bit higher efficiency across all power loads but the difference is small 2-4%.

Go with the Seasonic if you want the best performance you can get, they both have similar noise profiles (fanless in low load and pretty damn quiet). If you want to sleeve them yourself, then go with the Seasonic still. The Corsair model has a mixed bunch of cables (has flat and sleeved cables) while the Seasonic are all sleeved so sleeving would be much easier on the Seasonic. The two PSU's are so similar that they have almost (not sure on this) the same cable layout.

Both PSU's can also handle 1000W easy =)
