Can't tell, unless you tell us your full specs or the Power Supplies and Video Cards at least.

Reply with these information:

PSU1 and PSU2 Brand and Model
GPU Brands and Model, which of them are connected to PSU1/PSU2
Each GPU's overclocking settings

Then, others/I may try find out the reason why.

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 )
