@redxps630​ Would I connect a button to just pin 1?

redxps630 · Answer

Try connect pw+ to pin 1, pw- to pin 2.
Let us know if that works.
you may get some start up error if the other pins are not connected to anything

PS I do not have a 9020 USFF to verify user uploaded pinout.

I got the external power button to work on the SFF, now I get the power switch error message. Which pins do I need to use a jumper on?

@redxps630​ Did that last night with straight wires and ruined my mobo so I don't suggest that pinout.
