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

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.0

Motherboard 14-1 pin. Pin 10 is blank.
Pin 1-2 are the two lowest pin on your motherboard front panel header pic.

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?
