Power Supply Advice

[JSG]

Hello

I am looking to order a build in the next few weeks and I would like some advice on a power supply. The build is: i7 950 (will oc) Asus Rampage III Formula, 6gb Gskill PI 1600, 60 vertex ssd, Gtx 570 in a Antec 902 case. Eventually I will add another ssd as they become cheaper and I would like to be able to SLI a second 570 later on. From what I've read I think 750w will be enough to power this I would like a quality psu that I can take to future builds.

Should I purchase this one:

Or could I save some money and go with one of these:

Also are these big enough?

Thank you for your advice.

All of those PSUs are very good, all of them are more than enough.

The Seasonic won't give you any more performance or power from its parts, but it will be a little quieter. It will be more efficient. Whether that is worth an extra $30 is up to you.

Or how about this one instead? http://www.microcenter.com/single_product_results.phtml?product_id=0335251

Any of those should be fine. I powered a GTX 275 SLI system (similar power consumption to the GTX 570) and an overclocked Phenom II 1090T (similar power consumption to the i7 950) just fine on a Seasonic M12D 750 watt (exactly the same as the XFX power supply).

The best bang for your buck would be the XFX. It's an excellent PSU and it's the cheapest of the bunch. My next choice would be the 1000W Sparkle PSU from Microcenter. The other PSUs you listed are also excellent units, but they aren't as well-priced.

Thanks for the input guy... I am going to microcenter to get my i7950 for $200 (awesome) so I might just get the 1000w sparkle.
