Question Powering riser with 2nd end from PCI that's also in another GPU.

[Arnie699]

Bear with me,

If I were to plug 1 end of my PCI x8 into my mdb and on the other side the first x8 into a GPU could I then use the 2nd end x6 to power the riser of another GPU?
My issue is I want 1 PSU to power 4x gpu and 4x riser but I only got 6 PCI slots which will all be used for the GPUs (2x 3080 (4 PCI slots) and 2x 3060TI (2 PCI slots)) and I only have 3x molex cable so 1 riser is left without power.
Am I a mad genius or crazy?

Thanks in advance so I don't burn down my house.

What? Make a drawing or something. Can't understand anything.
List full specs of your system. Include also model name of PSU.

What is "mdb"?
"PCI x8" - is this PCIE x8 raiser cable? or PCIE 8pin power cable? or what?

Based on your prior post you are going to overdraw this PSU. Stop trying to take shortcuts and buy the proper PSU to do what you need, or yes, you will burn down your house.

Hope my inner artist can explain what my words couldn't. It's still somewhat simplified but detailed enough I think.
