I have a 4 GPU build: 3*1070 + 1*1060 + PSU Corsair RM750 (4*6+2 pin)
Would it be right just to connect only GPUs directly from PSU to the 8 pin connector on the card without powering risers?

still, need power because Riser needs power max 75W both Molex or 6 pins.

Is PSU power would be enough for that build?

Every time I want to build a Rig, I always calculate a standard GPU that needs Powering because my rig is stable and rarely problematic. (Yes, I know if doing it with undervolt total powering is not same.)

This's safer calculate.

1070 has a TDP of 150 W x 3 = 450 W
1060 has a TDP of 120 W x 1 = 120 W
total = GPU requires 570 Watt power then 750 W - 570 w = 180 W remaining power. Not to mention SSD, RAM, RISER that has not been calculated yet.

So 750 W, not enough

I totally disagree. I have a set of 3x570 + 1x1060 mining Eth taking 500W from the wall. Of course I undervolt them otherwise it would be close to 600Watts. So its clearly ok to have a 750 PSU for those cards (1070 are close to 570 in terms of consumption) provided that it is a good one.
