GPU Not Detected.

Hi, my GPU (Gtx 1070 SC) is not being detected by the bios in my z370 gaming pro carbon Mobo or device manager. I’m assuming my Corsair RM750X is suffecent and I know the pci lanes are good on my motherboard because the card lights up when powered on, but it is not getting a video signal nor being detected.

I have also tried reseating the gpu and updating bios.

I have also used a different card that I know works but even that card doesn’t get a video signal.

  1. TOP SLOT near CPU.
    CMOS clear work?
  2. Why didn't you insert that actual PSU cables into the card?
  3. I tried both of these things. Ended up doing an RMA on the board.
