My Psu is Corsair RM750. I didnt have any spare cable as well but I did try it in different pcie slots. When ever I would turn it on with the GPU it would give a slight kick to the CPU fan and then everything would be dead. Actually I just gave the card to the service centre.. Let's see.. hope I get a 1080ti as replacement. ? I did go through the trouble of disassembling and reassembling the whole thing twice... My card didn't sag as long as I screwed it in.

Whatever happened in the end? Was it the GPU? I'm having this very same issue. But with a GTX 1080. I don't have any spare components (Psu,GPU,mb) to test out. But the PC works without GPU. (I7 6700k, Asus Ranger VIII) So I guess it's safe to assume that I'm in the same boat as OP? And my GPU shorted internally? I have warranty.
