anyone familiar with supermicro H12DST-B ?

Hi,
i’m looking at H12DST-B. have read the manual back and forth, few times, but still don’t understand how power comes into the board. any idea?
thanks in advance.


Pretty sure its that stub on the top left of the picture

So would be the pcie looking connectors next to ram (could be wrong)

no seem to be nvme connectors (maybe power there too?
