Probably.
Guru3d recommends 700w although their figures suggest a good quality 650w ought to be fine
I had a XFX 550w PSU fail after running HD 7850 crossfire overclocked with this rig after about 3-6 months so I'd make sure you have at least 850w imo, especially as you have a higher powered CPU (I didn't have a overclock back then on my i5).

Your SuperFlower Leadex GOLD 650W PSU used 54.1A +12V, A GTX 970 card used 28A, SLi will add 15A so GTX 970 SLi will used about 43A. I think your PSU will do fine as long you don't overclock.
