I have an ASUS 4090 TUF OC edition that comes with the power adapter (4 X 8-pin lines connected to my EVGA 1600W T2 PSU). I don't see how the PD12V_PWR cable is relevant? Manual says:
"To support 60W, please install the power cable to the 6 pin PCIe Graphics Card connector (PD_!@V_PWR) else only 27W will be supported."
1st, the cable that came with my ASUS 4090 TUF OC edition uses 12 pins for power and 4 additional pins for power verification.
2nd, the cable provided by my X670E Extreme MB is about 3 inches long, there is no way this could connect to anything?
Do I need this connection give the above, don't really understand what this PD_12V_PWR is supposed to do nor what I can connect it to?
