I wouldn't recommend it. In a dual PSU setup, the PSU that just powers the VGA power inputs uses more power than the main PSU powering the motherboard, all of the risers and accessories. A 500W PSU also won't have all the PCI-E or SATA cables you need for all the GPU's. I would recommend getting at least a 750W PSU for the GPU's and a 650W for the motherboard. That should give you enough power for up to six cards and all the connectors you need. Just make sure it's at least a gold rated PSU from a good brand like EVGA or Corsair.

I agree. go for a 1000W PSU without hesitating, even if you have to order it online.

I am just a lowly member, so my advice goes against two above seniors, but I agree with Vann, up to a point that it has to be gold rated.
1000W PSUs are overpriced.
I would go with two 650s.
Also make sure not to use blue/black wire shorting method. Use add2psu  or cable solution.
This is perfect

In a dual PSU setup you won't have enough wattage or PCI-E connectors to run 6 full size cards on a 650W. The EVGA 650 W G2/P2 only has two PCI-E connectors. You need at least a 750W, that has four PCI-E connectors.

can one 1000 power 6 x 1070 FTW which need 2 vga for each card? I think a 1000 comes with 5-6 vga max so how do you do it?
