hi
i bought this PSU
https://www.anandtech.com/show/10820/the-zalman-zm1200-ebt-1200w-psu-review/2and it seems to run fine except the notorious issue of not having enough cables with many PSUs, i got 6x PCI cables and that was enough to run 2x 3060 ti and one dual pin 3070 and two risers !
i was thinking of using the molex cable since i got plenty to run the risers, my understanding risers use 75w ? is that consumed by the card or the riser itself

could it go more or less ??!??
what about using the molex cables isntead of PCI-E cables ??
i need a definitive asnwer regarding this please not just speculations !...
and of course am not gonna touch the sata cables !...
thanks,
the riser only consume around 15watt or less, and dont use molex to pcie, it will burn your cable, better to buy pcie spliter can handle up to 150w for safe long term use, or buying other pcie cable
