Quote from: hen6e on February 13, 2018, 07:04:53 pmAs I have learnt, the p1 connector pinout should be as shown,but I need your confirm.
The 10、1 Pin is output for 5V equipment like sata from VRMs on the motherboard.
The 16 pin is a POWER_GOOD signal,which trun to HIGH when the PSU finish startting period.
The 17 pin is a 5v stand_by voltage which is different from z420's 11V.
The 18 pin is a negative 12V input for RS232.
The 8 pin is PS_on,connect this pin to groung will trun on the PSU.
The 9 pin PSU_ID tells the motherboard which psu is installed ,it is different from standard ATX psu.
If you have oscilloscope or logic analyzer, please capture the waveform of PSU_ID.
Thank you!

24pin -> 18pin
