| May 27, 2020 at 15:50 | comment | added | Martin Z | @RonBeyer - sorry YES you’re completely right! (I added this one now) I am wondering what can be done that it is working without the 8-pin-cable being connected to the original power-supply-pcb | |
| May 27, 2020 at 15:48 | comment | added | Ron Beyer | Am I just missing the question here? Are you asking why it doesn't turn on if the 8 pin connector isn't connected? | |
