The higher GPU power in GPU-Z is the right value, which is the same as the HwInfo GPU chip power + ~50 W for the riser. For a RX 570 without an undervolt, ~150-160 W is about right. You can also lower the power consumption by reducing the power limit to ~-15%, if it's stable.
Oh
I was under the impression that I did undervolt though, at least with overdriveNtool(?)

I pretty much followed this guide
https://mining.help/ to do that and I thought I was undervolting, I guess I was not then?
