Also if it is continuous you really should only do 80% of the rating. This would be 1920 watts for 120v on a 20 amp circuit.
I would only run one 8 x 1080TI rig on this setup. I use 225-250w per 1080TI.
You really should run 240v with this kind of draw.
Below is my 125amp panel dedicated to mining. Yes, I did it all myself.
How much did getting the this panel installed set you back, I think in the very near future I am going to have to get a 400 amp service 200 on the house, and 200 on the mining shed quite possibly.
