Slot draw (riser) is included in the card's TDP.
Yes, that's why I use safer calculated, also with how much power that motherboards needed.
I never use software calculation about power consumption, it will give more gap between what shown on a software and the real (at Wall), trust me.
I always calculate max power draw for each part.
The motherboard and the CPU draw less than 50 watts, not to say 20.
yeah, but I never found even at old computer that has 100 Watt PSU. It's called safer.
750W is perfectly enough for these cards. It will run at about 600W on stock load and 450-500W when undervolted.
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.
but isn't safe and will kill your cards slowly
