Hello,
 
The card has space for a 6 pin and an 8 pin connection. I currently have all pins connected to a 750 W Gold Power supply. Do I need to do this or is I too many connections?
I ask as it runs fine but I do get screen flickering now and then. 

Thanks, that is what I did. I was just curious as I saw another 2070 RTX card from another company and it only used 6 so I wondered if the additional 8 was for using multiple cards or so.
