I mined Ethereum about 3 years ago using the Nvidia 1060 and they never drew max power. Conversely, you could use nvidia_smi to limit their power draw without making much of an impact on hash rate.
I’d be surprised if it was any different with the current lineup of cards.
It would be really interesting to see what the M1 draws doing this. Probably not much. But then it’s not doing a whole lot of hashing either.
I didn’t like the noise and the price had collapsed. I sold the cards for a very good price. I would have made 5 or 6 figures if I had just left them on. Oh well, it’s not the worst financial decision I’ve ever made. Hell, I bought TSLA at $15 and sold at $30. F me.
