sorry to bump an old post...

but is this confirmed to be working safe?

i have 6x asus strix oc rx470's that run on 6 pin pcie, was thinking about running mobo/cpu/ram/ssd/pcie risers off a 650w corsair and powering the gpu's from bitmain apw3+ 1600w (s7 spu) .. just dont want to risk fkn anything.

or would running dual atx be a saver option? as i have a Corsair 1000W RMX sitting idle atm too?
