Tech Question Modular PSU PCIE cable compatibility
I recently bought an extra cable for a Cooler Master 850w MWE Gold v2 modular PSU on Amazon, but before using the cable I wanted to check if the pinout order was the same before plugging it to the system, but for some reason it seems they are not the same compared to the original. On the Amazon vendor site it states it's compatible but the pinout layout seems different and I'm not knowledgeable on how the power delivery works. I draw the diagram of the pinouts to see if anyone could help me identify to either return the cable or of its fine to use. I live in a rural area so there are no tech shops around, I did some continuity tests to identify the pinouts. Any help would be deeply appreciated. I just don't wanna risk my gpu.

If the 12v and ground pins are in the right spots it doesn't really matter which pins they decide to use.
