Is my power supply causing my problems?

I have a TR2 700w thermaltake PSU, and I used it to run two GTX 660 ti's. I decided it was time to upgrade, so I got a GTX 1070 strix. Now that it's installed, my PC will turn on, then off, then back on, then off. It keeps repeating this process. Every now and then, I am able to get it to boot up, but when I play a game or something, it shuts down. I know my PSU is 700w, but I hear it is really old
