Is this PSU big enough?

I already own everything in this parts list and am using it now however I want to add another 970 in sli to it but I'm worried my psu isn't big enough. I've gone to a few power supply calculator websites and they say I shouldn't need anymore than 550 watts however I've also seen some forum posts saying 600 watts isn't nearly enough for two 970's in sli. So help? Will it be enough? I haven't overclocked anything nor do I intend to. Any help is very appreciated, thanks! http://ca.pcpartpicker.com/p/KYW4cf

First, that CX doesn't even have enough PCIe connectivity. Listen to PCPP when it says there's an incompatibility.

Second, I'd use a different PSU; the 600W CX model is very mediocre. Typical recommendations are Antec, XFX, Seasonic, and EVGA (G2, GS, GQ, B2).

Last, 650W may work, depending on how over clocked the 970s are. 750W would be a very safe option. I'd get a second opinion before pulling the trigger.

No this will not work. That is a low quality PSU with not enough connectors. Absolutely do not do that.
