RGB/Daisy Chain assistance please.

I have a RGB cable marked pc_in coming from the rgb hub. I thought this was the main cable that would power all my RGB lights. So I have my AIO hooked up to the RGB header and then I have that daisy chained to pc_in. Then all the rest of the rgbs are daisy chained together. The AIO light is on when I power up the PC, but non of the other lights are coming on like the case or fan lights. Right now I’m not able to fully boot the computer to troubleshoot, but wondered if my understanding of the pc_in was wrong. I looked in my case manual and it’s really lacking. It’s the Phanteks G500A. What am I doing wrong?
