Please post your full specs here. Including your CPU, RAM, and PSU to calculate the bottleneck effect.
Most likely "YES" if it's paired only with your motherboard and CPU.
But absolute "NO" if you have PSU under 500w.
Uhh if it's a good quality PSU it does not need to be 500W.
Running a 430W seasonic fanless with my i7-3770 (lightly overclocked) and gtx 1070 for a while now with absolutely no stability issues. I've tested with a prime95 and furmark simultaneously for a few hours without an issue. Testing using a kill-a-watt I think it peaked around 250W max.
Ahh... I forgot to mention that one:
GOOD QUALITY PSU
Of course you can get GTX1070 and i7 running on a 430W PSU, It's
Seasonic PSU. They are well known for reliable and built with high-quality components.
I also use a high-quality 400w PSU to power my old C2Q+GTX960 build. No problem for 4 years (I swapped the PSU on 2013, if I not wrong) until the motherboard died, I'm surprised that my FSP PSU is not causing the problem and still going strong.
And for the OP, No need to upgrade anything. Just plug it into your motherboard, install the driver, and enjoy.
Your i5 will not bottleneck the 1070.
