I got my 2nd 1080 Ti Seahawk from Newegg last month for $709 + Destiny 2.

Currently started mining Zcash the other day and i'm running 95% power on both and getting 1400-1500 H/S

I have my computer hooked up to a backup PSU, and it shows current power usage in watts. Running idle I have about 150w-200w, and mining it jumps to 675w (Max on he backup I think).

Does this put my power usage at 500w that I should add into the calculator? If that is accurate then I'm showing about $4.20 a day with 2 1080 Ti?
