Hi guys, i'm building new rig with 8 x EVGA GeForce GTX 1070 SC GAMING ACX 3.0 Black Edition and i have 2 Corsair HX1000i psu's.
I'm wondering what is the proper way to connect the psu's. I'm using add2psu to connect the 2 psu's.
First psu will power the motherboard, cpu, ssd, 4 raisers and the 4 cards connected to them.
Second psu will power other 4 raisers and the 4 cards that are connected to them.

Is this right?

Because i read somewhere that the first PSU have to power all the raiser+mobo+cpu and ssd, but this way i will not have enough connectors to do it.

Please, give me some advice!

I have the same setup also. I used RM1000x instead and it have 4xPCIE, 3xSATA, which is enough to supply 4 cards per psu. But if HX1000i have only 3xPCIE cable then you can temporary share 1 of PCIE for 2 cards until you buy an extra PCIE cable.
