So I got my new Z370-A Prime with my I7-8700k yesterday. I put everything together and noticed how the ports on the GPU and the ports on the MB weren't working. I double checked the MB and CPU power pins and everything was secured well, so it wasn't a connectivity issue. I tried a bunch of other stupid stuff I read online and just came to conclusion that it was a bad MB. So the lights on the GPU and MB were working. The PC booted and ran fine. CPU fans ran well too. I already shipped back the MB to Newegg for a replacement but I still want to get to the bottom of this. If anyone has ran into something like this, I'd like to hear your story.
