the only problem i got , if i tried to connect all the 6 cards with 8+6 pins , i will run out of power source for all cards , and the only option to do this ,i'll buy 2 sata to 6 pin since i use 2 PSU , but that will only mean i'll be already used the full 2X750W cables for 6 GPU , if i'm to add more 2 gpu i wouldn't be able to do it thats why i'm confused ?
