As 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!
Thank you Roy. I think the 6-pin fan's pinout is connecting 6.5.1 together as groung, other pins are like generic 4-pin fan. Because of Chinese Spring Festival I can't test it in about 10 days. We can communicate with each other with a instant messaging software. As for power supply I want to use a server psu DPS-800GBA so I don't want to use that adapter although that seller is close to me. Thank you for your pinout again. Here is a photo of the orignal fan from Taobao.
I just bought this board a few days ago.By measuring the impedance of pins from the connector , I guess the pinout is as shown in the attachment.But I cannot confirm that.So, your measurement will be the final result. Finally, Can you share the pinout of 24pin-to-18pin adaptor?
