But the OP @altano uses the M11 board?
Note: The M11SDV-4C/4CT/8C/8CT/8C+-LN4F motherboard supports either 12V DC in power input or ATX power input. The 12V DC IN power input requires an 8-pin 12V DC IN connection to the JPV1 header. ATX power input requires an 8-pin 12V connections to JPV1 header and PJ1 a 4-pin power connector of an ATX power supply by power cable (24-pin ATX to 4-pin power cable for PJ1, Supermicro P/N: CBL-PWEX-1063). PJ1 allows motherboard control of the 5VStby, power on, power good, and ground signals from the ATX power supply.
