Good PSU for i5 8600k + GTX 1070?

[ElementAMD]

I'm upgrading from a GTX 1060 to a 1070, and I've been spending a couple hours browsing different sources and sites about whether or not my system would need a different PSU than what I have (Which is a Seasonic S12II-520 Bronze).

My system would be as follows:
CPU: i5 8600K (Stock speeds)
Cooler: Corsair H100i v2
MOBO: MSI Z370 SLI Plus
RAM: 16GB HyperX Fury
GPU: GTX 1070 8 GB SC GAMING ACX 3.0 Black
Fans: 3x 120mm HD120 Corsair RGB

Would my current PSU be fine with a 1070, or should I look for something with a bit more headroom?

https://www.evga.com/power-meter/ (for future ref it can estimate the size psu u need based on a few questions about your parts)

for stock speeds the 520 is fine.
if you ever do wanna overblock (and given unlocked cpu and z370 board are designed for it) you may wanna try for a 550.
