Please let me know if it makes sense?
This is the plan

PSU1 & PSU2 are connected to the wall plug (2 separate wall plugs)
PSU1 & PSU2 are connected to each other via ADD2PSU or similar (24 pin split)


PSU1 connects to MOBO/CPU and HDD for power

PSU1 connects to 3x cards and 3x risers using 2 MOLEX (can I use 2 separate MOLEX cables?) and 3x 6 PIN total — or I can use 6 x 6 pin instead?

PSU2 connects 3x cards and 3x risers using the same (or all 6 PIN?)



I have a 1600W EVGA Platinum as main and a 1200W CM Vanguard as slave. They both have 6x 6 PIN

Can I use these cables for 6 pin to 6 pin?
