Need PSU help for first build

I'm currently looking to have 1 GTX 770, but in the near future am planning on getting another 770 for SLI. Should I get a bigger power supply from the beginning or should I upgrade my PSU when I add another 770?
Also, assuming I went bigger to start with, would this PSU:http://www.newegg.com/Product/Product.aspx?Item=N82E16817182239
be enough to comfortably support 2 of these:http://www.newegg.com/Product/Product.aspx?Item=N82E16814130919&nm_mc=OTC-pr1c3grabb3r&cm_mmc=OTC-pr1c3grabb3r-_-Video+Card+-+Nvidia-_-EVGA-_-14130919
I'm definitely willing to go gold vs silver/bronze if it means power savings in the long run.
Oh, and I don't know if it matters but I'm planning on using an Intel Core i3570k for CPU with this water cooler:

(if that's important to know for power draw).

  1. That PSU will certainly provide enough power for your system.
    Here's a JohnnyGuru review of it's big brother, the 1300 Watter:

    It is manufactured by Super Flower using one of their better designs

    Two quick questions:
    Will 850w be enough to support the 2 GTX 770's, my i5 3570k CPU, and the water cooler? I read a review on toms hardware that said running two 770's would take a minimum of 850w PSU.
    Secondly, what's the difference between certified gold and certified bronze? I plan to use the crap out of this computer so PSU efficiency/quality will be important to me.
    Ok I lied, 3 questions. Is SeaSonic the best brand in PSU's in your opinion?

    That's a little more what I had in mind.
    SeaSonic makes XFX? That PSU had very few ratings on newegg o.O
    Also, thanks for help so far. I picked you as solution.
  8. Seasonic makes all XFX PSU's.

    Ok, I think that covers everything. I'll be getting the 1050w PSU you recommended :) thanks for your help.
  10. It's a nice unit at a great price , and plenty of horsepower for your future SLI.
