Welcome to Tom's Hardware Forums,
XFX, Corsair, SeaSonic are all good brands - I personally would be looking at the SeaSonic X750 here
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
or the CORSAIR Gaming Series GS800 here
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
those are both in the upper cost area.
If budget is an issue then perhaps the SeaSonic M12II 750 SS-750AM here
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
or the CORSAIR Enthusiast Series TX750M
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
or even the XFX P1-750X-XXB9 here
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Just a few options for you.

With the 3570k being a low power cpu (77wTDP) along with the GTX 670 also haveing a low TDP (149w) you can get a 650w and still power SLI , so if your budget is tight you can save a few bucks and get a quality 650w psu that has a nice high efficiency rating.

SeaSonic M12II 650 SS-650AM 650W ATX12V / EPS12V SLI Ready 80 PLUS BRONZE Certified Modular Active PFC Semi-modular Power Supply $104.99

CORSAIR Enthusiast Series TX650 V2 650W ATX12V v2.31/ EPS12V v2.92 80 PLUS BRONZE Certified Active PFC High Performance Power Supply $79.99 after rebate

You can also use the power calculator to see what you need for watts.

ASUS GTX 670 DirectCU II TOP Graphics Card Review
Quote:
Turning to power consumption, the GTX 670 just sips power, especially compared to the dual GPU beast. A solid 500 W PSU would be plenty for this GPU and an overclocked Ivy Bridge setup.


Add 177 watts

177+295=472 watts then to keep it under 80% max load 472/.8=590 watts

177+425=602 watts then to keep it under 80% max load 602/.8=752.5 watts

C12Friedman made some very excellent suggestions.

and that is also very doable . .i had added a "comfort zone"

By using the 425 watt figure given for the HD6990 instead of the 295 watt figure given for the GTX670 ?
