Hey, my weekend for PC repairs, I guess. My parents really old PC stopped working. I grabbed a cheap 400watt PSU and pulled the old one out (200w). The new one came with an adapter harness to allow the 24 pin connector to fit into the 20 pin plug on the MB. And the old PSU also has a tiny 3 pin connector, separate from the main one, that plugged into the MB. The new PSU did not have that connector, so I skipped it, plugged in the drives, and it works fine. Question, what is the small 3 pin plug for? And does the 24 pin harness do away with it?
