PSU1 AX1500i Corsair (MB connected to this one)
PSU2 x miner 1600
GPU : 1080ti Gigabyte 11g gaming (all the 8 GPus are the same)
OC the same for all ( Core 125 Memory 100 Power 225 )

Ok, the PSUs are different, this is pretty normal for two different Power Supply. Read the bottom part of my previous reply.

In addition, Corsair is a reputable brand which strongly suggest that your first PSU has a good power efficiency.
The second one is a Chinese Brand? (I never heard of it, honestly), it could be less efficient that makes it more power-hungry than the 1st one.

How can I calculate each gpu power draw with my OC setting and MB

Because before I got the Corsair 1500 I had EVGA 1600 and ran 9 Gpu's Now I barley ran 8, So I try to find the problem (The shitty Chinese PSU been fine with the EVGA and I dont belive the 100 W diff between EVGA and Corsaie made the diff
