ATX12V Connector - Mobo uses 4 pin but PSU has 8 pin Tags: Homebuilt Gigabyte ATX Systems Product Last response: December 9, 2007 6:54 PM in Systems Share toasty2 December 9, 2007 3:10:55 AM I bought a Gigabyte GA P35 DS3L which uses a 4 pin connector for ATX_12V but my PSU has a 8 pin connector. My PSU is a Silverstone 500W. I noticed that half of the 8 pin connector will fit fine into the 4 pin on the mobo...is this what I'm supposed to do? I've never had a PSU with a 8 pin ATX12V connector before. More about : atx12v connector mobo pin psu pin Ed_B December 9, 2007 3:37:05 AM I had the same problem on my P5B. I looked closely at the 8 pin plug and could see that it came apart in the middle. So I just used one of the connectors, you probably don't need to take it apart as long as it will plug in. Ed toasty2 December 9, 2007 6:06:52 PM Mine didn't split in half, but half of it plugged in fine and I just left the other half sticking to the side. I tested it and it passed POST and stuff (I don't have an OS on it yet). Can't find your answer ? Ask ! Get the answer Kari December 9, 2007 6:54:15 PM yep, thats how you are supposed to do it... some mobos need all 8 to power those quadcore cpus, but usually just 4 for duals Can't find your answer ?
