Well, if u upgrade from a HD 5450 to HD 7770 , u will nid a 6pin power connector ~
I would recommend u upgrade to HD 7750 better as it same as HD 5450 no need addition power connector ~
Well like I said, I've already purchased it. If worse comes to worse I can sell it online, but even though I will have severe bottlenecking, could I play a game like Battlefield 4 on low-medium with no real issues?
