Do you have to plug in both PCIe cables into the graphics card? Tags: Graphics Cards Cable Graphics Last response: October 31, 2011 9:31 AM in Graphics & Displays Share wanderer October 31, 2011 6:59:43 AM Or is that not enough to power it properly? I recently got another 6950 so that I could use it in crossfire, but the cables that it came with won't work with my PSU. Right now I have 2 6 pin cables plugged into my old 6950. I'm just wondering if I could take one out and use it on the new card, or if I'll need to buy another dual 6 pin cable.
