850w uses 530w for both 1060 and 1070, so yes, you can add more 1070 units.

I believe you're mining.
You're allowed to do so unless you intend to overclock, as that would raise power consumption.
From a theoretical standpoint, you could upgrade to a 1080, because adding another GPU beyond the 1070 isn't possible.
I assume you're extracting resources.
Yes, you can, unless you intend to boost performance beyond limits, as that would raise energy consumption.
From a technical standpoint, you could incorporate a 1080, because adding another 1070 would be impractical.
You should be able to adjust them further. I mentioned using a watt reader to check a draw of 530W. This means the device is showing how much power it draws from the wall, which is the AC value that’s higher than the actual DC output. A well-rated PSU would only convert about 82% of AC to DC, so the real power inside the PC would be less than 500W. You still have room for another 350W. As discussed, this amount could cover adding a 1080TI. In terms of efficiency, I’d prefer to increase the power limits on the cards instead of upgrading hardware. It might yield better results. I’d experiment with adjusting the power settings and observe the outcome.
