Friend is getting the "please power down and connect the pcie cables to the graphics card" error when installing a used PNY GTX 960. She currently has 600W and only 1 6pin connector. Old card still works when she puts it back in. This is what she currently has for specs, however she has something different for power than whats listed in the group.
