So my AMD RX 580 Graphics card has been crashing a lot and not performing up to what it should be. When I originally installed it I upgraded from an RX 560 and since the power cord fit the card I decided not to use to one provided with my new card. I could just be worried for nothing but I want to know if I need to put the other cord in or not. The current idle wattage is 7 for my pc but I checked online and it says it was normally around 16 or more, I'm not sure if that amount of difference really matters but I want to check. (Edit: So could it also be the power supply? Mine is a 400 volt when the 580 wants a 500 volt.)
