Hello, I'm going to replace the graphics card with the asus gtx 970 strix which has only an 8-pin connector and my power supply has only 2x6pin for the graphics card, the power supply is "https: //www.morele.n...-he-500-387227/". Will the adapter be able to do it or do I need to replace the power supply if I want a graphics card with an 8-pin plug?
