I played with the connector and also in my case the connector that switch off the power supply is the one like yours.
On this connector there is 12V, 5V and 3V.
Is the only one with 3V inside.
I attached an external supply in parallel on the 12V metallic pin and the green led inside power supply switched On, and the MB try to start the fans.
Maybe i have only a Powersupply problem.
You can try the same ?
Your green led inside power supply is On ?
For now my hypothesis is that the power supply already had some random problem,...Leave a comment:

Do you know if the 12V must be present always ? Or the 12V will switched ON after the POST ?
If I press the power button, only the 5V will be present.
Maybe I can connect an external 12V in parallel to the original 12VLeave a comment:

Hi to all,
I have the same machine, Z8 with FMB-1703 MB.
I have some question:
1- there is two Bios chip onboard ? Also in your .rar file I see two .bin
2- what does this two chip ? I need flash the two or only one is enough ?
3- the two chip is the two that are visible in my attached photo ?
4- if I flash by a Ch341 your original file from the first post, without modification, will the machine work ? I imagine that only the serial, mac, ecc will be different but working.
Thanks for your help...Leave a comment:
