I also need advice. I already have 2x 3 1080 ti. I can get 1080 ti for 700euro, and 1060 6gb for 275. I plan to mine eth until difficult dont jump, then maybe ubiq or something. 1080 ti for zcash or something. What is better 1070 8gb 420 or 1060 6gb 275. I think 6 1060 6gb with 750w psu is rly good deal.
why the 1060 6gb? good for gaming, but no use for crypto. the 3gb version is under 200.
only 750w (peak) for six 1060 did not work (for me). a 750W psu will give you just 750W * 85 - 92% = ca. 650 - 700W (max).
but each 1060 takes 100 W and the CPU / MB another 120 W. you should not run 24/7 on max.
i use 2 psu (1 x 550W and 1 x 650 or 750W) for each mining rig with 6 x 1060 3gb. i found this solution more stable than 1 x 1000 W psu
