Yes, it's will work : all tensions are ok.
But be carrefull with multiples adapters.
I'm a little surprised that you have to make such cabling with an EVGA PSU : EVGA PSU are the PSU with the more GPUs output : 6 or even 8 with the 1000/1200 W and you are talking about 1600 W...
well ye, this one has 9x VGA Ports. But I want to have 4x 1080 TI (2x8pin each) and 2 1070 (1x 8pin each).
So you have 6 gpus and you need 10 VGA ports. But as told, it "only" has 9 .. so i have wanted to reuse 1 cables twice .)
