Not sure if this is the right forum, but either way, I have a Rosewill Glacier 500w 80+ bronze, also my build https://pcpartpicker.com/list/7r7f9J I am trying to get a HD 7970 but PC part picker says I need another 8 pin connector. But in my hand is a 8pin to 2 x 6+2, (8 pin going into the PSU) is this just a glitch or am I missing something? Do I need a better PSU? Thanks!
