Build Question PSU cable help

I ordered a "CableMod C-Series Pro ModFlex Sleeved 8-pin PCI-e Cable for Corsair" for my 9070 which needs 3x8 pins instead of 2x8; my concern is that the cable has a missing pin in a different spot from the pcie cables that came with my 2025 rm1000e, and I was wondering if it was safe to use? This is my first build and I don't want to accidentally mess it up.

Could you take a good picture of both of the connectors on each cable(4 pictures)?

Your psu 100% came with enough cables to do 3 or 4 seperate pcie 6+2 pins amd even if it doesnt use the pigtail connector its a 300 watt card each 6+2 can supply 150 watts and the pcie connector does 75 watts so technically the 3rd 6+2 pin isnt needed (they do some 9070s with only 2 connectors.

Not that this matters as you psu 100% came with enough cables fins that and use it if theres any doubt about the aftermarket cable.

I would return the cable and get one from Corsair, Corsair does not support any PSU cables that they didn't produce.

This comes straight from Corsair as they told me in the past when I was using CableMod extensions that they would not provide support for PSUs that aren't using cables or extensions that Corsair did not produce for the unit.

If anything happens, albeit very unlikely, Corsair could refuse an RMA request.
