So I purchased some 180 degree adapters to clean up the 8 pin cables on my 3090 and I checked continuity. All the grounds are connected together and all the 12 V are connected together. I don't have an issues with the grounds all being connected, but seems odd that the 12Vs are all connected. Is this correct? Unfortunately there are no trusted companies that I could find that make these, just Chinese randomness on Amazon.
