PhoenixMiner 3.5b works stable for my only 2x Sapphire RX580 Nitro+ rig but I don't see any change on my GPUs power draw when using new green kernels.
I get same hashrate (30.3MH) with same GPU only power draw in GPU-Z sensors tab (90W for every card) when using new kernels.

Never use GPU-Z for power measurements, hardware watt meter is the only sure way. Everything else is just software estimate
that is often pretty wrong

Theyre not expensive, either:

We have found even some plug-in watt meters are not accurate and can easily become uncalibrated.

Depending on your voltage you can find a cheap metered PDU that will tell you your amperage draw for under $150.
