It's an xbuddy board. I see that on yours now. You are missing the white connector. However, you can see where it should have been. And while the white wire pin is ripped off your PCB, you can still solder a jumper wire to the resistor or cap I pointed out.

Wow! I've never seen that board. Are you sure it's an xbuddy for a MK4? Can you take larger pictures of the rest of the board? There should be a version number on it as well.

Could you take a large one of yours please I see power panic written on jmshirly one but there is no port near by so I'm wondering if it's a faulty board

This is what I'm seeing on my board. Sorry, it's not a great picture. But I feel like it's not even the same one.

If you absolutely need to, these are some of the pins you can short to GND to trick the power panic into thinking it is ok.

The problem I'm having is that both the little pins on the board broke off and it was literally just a small box that slides onto the pins. A friend has been trying to solder directly onto the contact points with zero success as he can't get the solder to hold. Looking at the pictures in that github link makes me wonder if something pulled off the board that wasn't supposed to because I never had a small white box on the board when I opened mine up for the first time and found it disconnected. If that's the case then I'm about to try the solution mentioned by getting some new wire and trying to solder in a single line in the configuration mentioned.

Everyone! Other users found a solution to this and posted it in my Github issue.
Conclusion: Disconnect the black wire from the power panic, while leaving the white wire connected to "V-" (or any other point tied to PSU negative) will disable power panic AND disable the cable check portion of the power panic.

Thank you very much. I can confirm: works fine with my Meanwell PSU :-)
