...Been mining ETH and my hasharates have been 30-31 per 1070. I never thought you could have a PL "too low" if it's within the supported wattage of the card. Of course, some GPUs, like the MSI 1070 Gaming X requires minimum 115 watts but some other 1070s can go to as low as 90 so that's why I say average is roughly 100W per card. It's bee stable like this for nearly 2 weeks now so I don't see why it's a big issue if it's stable?

I'll get my "DOH!", for mining ETH with that many NVIDIA cards, out of the way right off the bat.

That being out of the way:

Granted, in the real world, the loss isn't 1:1; however, for ease of math, we'll pretend it is.
If you have a 150 TDP card and you down the output by 30%, then you have taken a 1500W set of cards and lowered them to 1000W. Now you have a 500W reduction in power that is the same as the total amount of power required to power 3.3333 cards at full power (for ease of math we will call this 3 cards). So, you have an effective rate of 7 cards and have 10 cards sitting on the rack. To what end?

Yes, it's at the lower end of stable, but what is the point?

Not counting the 1060s and your other rig(s) that make up your other 8 cards....
Even if my numbers are off by ¹/₂, and we pretend you paid wholesale ($375) prices for those cards, you have $624 worth of cards sitting idle the save $438 per year in consumption while giving up 49% of your potential earnings (by running cards at hashrates of as low as 30 when they can hit as high as 58).

It's something that makes less and less sense the more and more cards you run.

Your math doesn't make sence in real world. Either he run his 1070 at 100 or 150 wats PL, the hashrate for ETH will not increase, it will remain at 30-31 MH/s. So he is effectivly saving 50 watts per card while getting the same hashrate, what's wrong with that?
