I5 2500K would bottleneck the processor but would get the job done. It's a very good power supply if you choose you to overclock it.
not a power supply...duh its a processor CMON MAN
I think that was a typo, anyways, an i5 2500k when overclocked is still a decent performing processor to this date. However pairing it with a 1070 or 1080 isnt a very good idea. I would say a GTX 1060 6GB would be a very good option, you may actually be enough for GTX 1070 if it is overclocked high enough.
