I have a power supply with dual 6 pin and I bought this card used so I dont have an adapter and all the adapters I look at online look like they dont fit. Could someone link me a dual 6 pin to 8 pin adapter that fits a gtx 960 please and thank you.
Most GTX 960 have a 6-pin connector. Some have the 8-pin. The only concern I would have with recommending an adapter is the quality of the adapter and the thickness of the wiring used. There's no regulation on that so they could (and sometimes do) have too think of wire and can melt if too much power goes through it.
Best solution is to get a power supply with the proper connectors.
