Psu req for sli 570

Im building the same rig as you. I asked a moderator in the psu section what his thoughts were and they were about the same as your link. I have a seasonic x750 and he said that would be fine. So you'll be fine with an 850, especially if its gold certified(and its seasonic lol).

Personally I'm going to look at 850s between corsair, seasonic, and pc power and cooling. I know seasonic makes corsair's PSUs but Ive read that corsair has better customer service. PC Power and Cooling is basically on the same level as Seasonic.

Oh and Im not sure if you know already or not, but you should get a modular PSU(just makes building/upgrading much easier, as you only have to plug/unplug and nothing more really). Hope this helps 

Corsair, Seasonic, PC Power and Cooling, Antec and XFX are all top tier.

My bad forgot about Antec. Ive heard a lot of people recommend the XFX 850w black edition thats silver certified, but i havent seen any 850w psu from them that are gold certified. Ive also read many consumer feedbacks on newegg saying that their XFX makes an annoying squealing sound, so i left that out.

Who do you think are the top two out of those five?

I think you can safely buy any of the five.

If you read the reviews, you will always see a couple of posters who got DOA samples; that happens. A user is more likely to complain about a defective sample than praise a unit that just works. Newegg RMA is good if you happen to get a bad sample.
Perhaps customer support might be the deciding factor. I like those products where a company rep takes the time to respond to issues raised with a problem with a product.

For what it is worth, several years ago, I had a question about a PC P&C psu(before OCZ bought them), and I called the company. A real voice answered, and said let me get a tech on the line for you. The tech was knowledgeable, and answered my question. I like that kind of service, and I think PC P&C is still largely autonomous.

My most recent psu purchase is a Seasonic X-750 which has been perfect.

I would suggest this PSU (it's the one I have   )

But they probably are all good choices.

I'm getting the bronze 850 corsair because i have budget i have to keep up with.
