It's an Asrock B650I Lightning Wifi Mainboard (AM5).
Here's an excerpt from the mainboard manual:

1. As you can see, the board has a PWRBTN# pin (2 below empty pin/6th pin). The question is, where do I short this pin to? GND?
Most guides mention shorting both power pins, mine has only 1.


2. At the top is a warning about shorting headers and connectors, it'll causr permanent damage the mainboard.
Does this warning have any bearing on this matter?
Obviously don't short short usb connectors etc, but they explicitly mention "headers and connectors".

Case needs more transit time, thus I'd like to test components for faults & update (the burning asrock zen) bios beforehand.
 
Look, if you're that worried about it, don't do it. But if you are ok, you don't "Ground" anything to anything. All you do is jump the pwr pins TO EACH OTHER using a small flat tipped screwdriver. And yes, you ground PWRBTN to the ground next to it using a flat tip screwdriver or other small device that is small enough to do so without touching other pins. It's really not hard, but you do need to be careful and precise about it.

Thank you.

Yea for extra safety I pulled some old microelectronics female to male jumper cable and will connect PWRBTN and the ground pin above it.
According to some videos, touching them for a few seconds is enough.

That way, I'm sure accidentally touching other pins will be ruled out.

Just want to make sure it's PWRBTN & GND and not some other pin. Better ask (slightly embarrassed) twice than break once.
