Does this card,http://www.amazon.com/MSI-Graphics-Cards-N750Ti-2GD5-OC/dp/B00I6DLIE0/ref=sr_1_3?ie=UTF8&qid=1394463389&sr=8-3 require a 6 pin power connector? I know that some versions of the gtx 750 ti do require a 6 pin power connector. If this card does require one, please let me know. Thank you
