Hello, the pin showed in the image is the ground. Though the one with the benl link is also with a ground. You can see it in the picture its a piece of metal shown in the inner diameter of the female plug. You should be aware that if your male plug is not provided with this connector, your either can’t connect it to this socket or you will not have a ground.

Thank you, I’m gonna try it when I’m back home. I hope I don’t see something wrong as I’m on Linux since a year or so :) Thanks again

Thank you for your quick guide and explanations. I currently dont own an AMD GPU though I plan to acquire one if it’s worth it. So this may be useful.

How did you manage to get the power consumption on in idle mode ?

You can still drop windows and boot to KDE (the desktop is based on it for the steam deck) :)
