yeah i understand, but the problem is that if you have like for example 8 gpus and you need 2x 8pin vga cable for each, you will need 16 cables.
Which is ok when i consider 2x 1600 psus. BUT there is no way of having all gpus on 1 psu. and the rest on the second one.

You can run some of the gpu's to one and fill up the other PSU.. I have everything connected to one PSU (mobo, risers, sata, etc.) and an additional 2 GPUs, and then the remainder GPU's (VGA 8+6) connectors connected to the other GPU.. The EVGA power supplies comes with a little plastic black tester, I just hook that up to the 2nd PSU and then turn it on using the On/Off switch in the back seconds to booting up the mobo and it works like a charm.
