OCZ ZX 1250w PSU or Corsair CMPSU-1200AX Which is the best

I am looking for an 80 Plus Gold PSU and want the experts opinions on these 2 models. I plan on having 2 high end graphic cards eventually and playing the newest high demanding games. My system will be the Sandy Bridge with i7 2600k CPU and the Maximus IV B3 motherboard with 8GB G-Skill DDR3 ram. Will have the ASUS Radeon HD 6970 video card to start and may add another one later.

When it comes to power supplies, I usually choose Corsair, Seasonic or Antec. So, based on the choices that you have provided, I would say the Corsair.

A 1250W is probably a bit on the higher than necessary front. Maximum PC did their dream machine this year with a 1500w PSU, and the machine consisted of 3 x GTX 580 SuperClocked, 5 hard drives, and an overclock on their Core i7-2600k and they had plenty of power. I would think 1,000W would supply all of the power a dual 6970 setup would require.
