This is my current build: http://pcpartpicker.com/user/DanielIskander/saved/31LU
This is my PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E16817182133

I was wondering if my PSU would support another GTX 770 in SLI. I was also wondering if I could over clock both of them and my CPU without a power problem. PCPartpicker says my estimated wattage is 438 so I thought it wouldn't be a problem, but after some research, I found out that wattage isn't the only factor. It was something about amp rails that I didn't understand.

If my PSU can't handle it, would this one be able to?http://www.newegg.com/Product/Product.aspx?Item=N82E16817139056

Any help would be appreciated!
Thanks

Nvidia recommends a PSU that supplies 62A over the 12v rails. Looking at that PSU under specifications, you can see the +12V supplies 54A. This does not met the minimum requirements set by Nvidia.

That being said, I've seen people running 770s in SLI on 750W power supplies before, so I'm sure that number is exaggerated a bit, but that's your gamble to make. Personally, I'd be getting a quality 850W power supply if I were in your shoes.

Thanks for the help, I thought it would be a better idea to get the RM850 anyway.
