I have a non-flashed EVGA (half-sized, PCI-powered) GTX 750 Ti, which I use to run my 4K display at 60 Hz. I currently have it installed in slot 3 of my 2009 cMP. I understand that there could be a performance hit if the card is not in a 16x slot (and I might have seen some minor screen artifacts), but I rarely use the GPU intensively. The card seems to work fine for my needs. My concern is power. My graphics card is rated at 60 W. I know that the 16x slots can provide 75 W each, and I believe that the 4x slots can provide 25 W each. My question is: can the computer's logic board be damaged by having my card installed in slot 3?
