I have a sonoff wifi switch, the app tells me the effective consumption in real time

After many tries now i'm stable @116,8mh/s, 514watt

Thank you!
And what about power consumption? is 540watt a good target?

Hi all,
first of all.. I'm Tommaso from Italy and this is my first thread.
I've read many threads in here, it's full of amazing info and interesting people, congrats.

I just set up my first mining rig with 4 sapphire rx570 8gb nitro+ (hynix memory),
and a corsair rm850i psu (80+ gold).
I'm using claymore 11 on ethermine.org and I'm stable @117mh/s consuming 540watt total.

Is this a good or bad score?

THANK YOU!

Tommaso
