Corsair HX850 has as many amps on 12V, plus it's better quality, more efficient, and has a longer warranty.
The Op asked to pick between the Antec and Cooler Master, I don't see Corsair up there anywhere. Second, I have the right to my opinion just like you have the right to yours, respect that.
I frequently find that many posters over estimate what wattage is required for a particular build. Kudos to xbitlabs for helping me in my wee 'mythbusters' quest.
Jonnyguru is my preferred site for PSU reviews, they do very thorough work. But their ability to cover all PSU models is limited by their very thoroughness, so xbitlabs is for me, a good second choice.
