Gigabyte motherboard GA B75M-D3H

The subject motherboard manual shows that the ATX 24 pin assignments has a -5 volt to pin #20. My PSU does not have this pin. Anyone has this board operating without any problems without pin 20? Understand that this pin was eliminated over the years with newer atx power spec.

I don't believe modern motherboards use the -5V circuit anymore. Can you post a pic or send a link of the diagram that shows your board having a -5V pin? Most ATX PSU's 24 pin connector have the #20 pin N/C.

Sorry I'm working off from my iphone so I can't see an upload button to send you a pic? If you don't mind, I can send you an email of that pic provided you give me your email address. Thx.

It doesn't matter. I just checked. All MBs seem to have a dummy pin in that position. You are fine with plugging in the PSU connecter as is to the MB header.

Makes me wonder though why the board manufacturer provided in the diagram in the installation manual a -5 volt to pin #20 on contemporary board running on the LGA 1155 socket with PCI express slots? Just an oversight? Anyway I send a message to the manufacturer who is at overseas. Possibly a remote chance of receiving a reply. Thx
