Does my 7850 have the 7870 PCB? Tags: Graphics Cards Power Graphics Last response: September 16, 2012 9:15 AM in Graphics & Displays Share mrbeanladen September 15, 2012 3:16:01 PM I see that it has another space where the 2nd (7870 has 2 6-pin connector slots) 6pin slot should've been. Can you also tell me what power phase it uses please? BIG PIC You see, there on the bottom, those holes.

However, the 7850 has a few disabled units and is slower than the 7870. As for power phases, the 7870 is 5+1+1, the 7850 is 4+1+1.

My 7850 has 1.038v stock and 7870 has like 1.1-1.2v stock. Would it be ok running at 1.2-1.225v in games? Can't find your answer ? Ask !
