My first question is what Radeon HD Cards do you have? Two 5770's compared to two 5970's are two different animals. You don't need a 1200 Watt PSU to power those cards unless its something like two 5970's and then a ton of hard drives and fans. My personal recommendation is to stick to Corsair AX (or the older HX line) or Seasonic power supplies.

Any of these should work but let us know which cards your using to Xfire or if you have something that would justify using a 1200 Watt PSU. A PSU typically likes operating around a 50%-75% load for maximum efficiency.

1) Seasonic X750 http://www.newegg.com/Product/Product.aspx?Item=N82E16817151087&cm_re=seasonic_750w-_-17-151-087-_-Product
2) Corsair AX750 http://www.newegg.com/Product/Product.aspx?Item=N82E16817139016&cm_re=corsair_ax-_-17-139-016-_-Product
3) Corsair HX750 http://www.newegg.com/Product/Product.aspx?Item=N82E16817139010&cm_re=corsair_hx-_-17-139-010-_-Product

Like I said depending on price, and what your actually going to Xfire should make a big difference in the PSU you need.

You should not be experiencing over 500 Watts unless you have two heavily overclocked GPU's and a heavily overclocked CPU. http://techreport.com/articles.x/17618/15

Just out of curiosity, are you already running two 5870's in Xfire or are you planning on doing it or is your PSU giving you problems? Your Corsair 750TX is a very good power supply and you definitely should have no issues running it.

You should be all set. The PSU has enough amps on the 12V rails and it also has the pre-requisite of the 4xPCIe 6-pin power connectors.
