PS for 2500k + dual 6950s

[jabberwhacky]

Closing in on my final build and it should look something like this:

2500k
2x HIS Radeon 6950 (either unlocked or just overlocked, I'll know when I set it up!)
8gb RAM
128gb SSD
1TB storage drive
Sabertooth P67 (or) Gigabyte P67A-UD7 (or) Asus Maximus IV Extreme (I can't for the life of me decide, keep reading mixed opinions about x8/x8 PCI versus the x16/x16 NF200...I do plan on going Eyefinity multi-monitor)

I read similar setups and the consensus was 850 was plenty. I found this Corsair for $190 but also this non-Gold version for just $120 (AR). Either of these good? Is the Gold worth the extra money? Should I be looking at a different brand?

Also, I'll be using this in Korea. I don't think that'll be an issue, I'm assuming most power supplies are 100-240. Last time I was there I was able to use my laptop charger with just a $.05 converter (from the line prongs to circle prongs).

I would stick with the non-gold Corsair and save the money!

850W should be fine, Corsair is great.

Personally I'd spend the extra money on the AX because of the efficiency, but there's nothing wrong with the TX.

You could also consider a middle ground and getting the HX:

80 Plus Silver and modular (except the 24-pin power I believe).

Yep an 850W would be the best choice although a quality 750W would run them as well.
Best deal XFX Black Edition XPS-850W-BES 850W -$149.99/
$109.99 after mail-in rebate

Thanks guys. I ended up with the HX; I found it on Amazon and I happen to be on a Prime member trial, which means free 2-day shipping, and Amazon doesn't tax us Californians, so after rebate the HX will be just $145.

I looked at the XFX but multiple reviews mentioned a high-pitched whine that didn't stop until you flipped the power on the unit itself, and that was enough to scare me away.
