Soooo, this took a while…..
That is, before I dared to cable up the board to the PSU……(and aswell as other priorities did prevent me to move ahead)
After recap and missing the original PSU I never got to test it before.
As that PSU had an extra connector for startup control and thus never really figured out how that connected, so I thought to skip it for now.
Today I figured out the ATX connections and did connect it to the board, and it basically works!
I am happy !
Have a great Easter
