On my new board there is a 4 pin power connector and I am trying to figure out exactly what it is for.
My mobo is an ECS A790GXM-AD3
It is not mentioned in the manual, and I don't have my CPU yet so I'm kinda clueless. My current theory is that its for a fan so I can control it.
Here's a pic
It's right next to a 3 pin, so thats why i think its for a fan.
I have the AM2+ version of this board and its not on that one.
