Yes I know, but the video cards I use only need 1 pci-ex cable !!
I just want to know if the source will hold out.
Thanks

For 6 gpu's you're going to want at least 6 6pin pci-e connectors.
Ideally for versatility and efficiency you'll want 12 6pin or even better 6+2pin pci-e connectors. Because some of the higher power draw video cards require 2 pci-e wires.
1 pci-e per card, you only need 6 pci-e connectors. If the PSU you have found has that feature then you will be okay.
Worst case you can run a server PSU secondary to supply the extra pci-e power.
