GPU driver error

Hi, I got an issue this day.
HiveOS crashed everytimes I tried to connect my new GPUs with this message:

I explain the situation: I have only one rig with 3GPU connected to one PSU (Corsair), it works fine until I connect the second PSU (Antec) with 2GPU.

I dont know why and I need help. I also saw a HIGH load average and the CPU temperature increase by double when I connect this second PSU.
