I'm building a pc for the second time and I ran into a bit of an issue. I recently got a 850 watt power supply and tested it with the paper clip method. It worked fine. The fans were spinning and my connected fan was also spinning. However, when I connected all of the cables and set it up, the power supply wasn't getting power. I did the paper clip method with everything plugged in and the fan still spun which means that the problem has to be with the motherboards connection to the power supply. I switched out the 24 pin connector for my old one and it still didn't work. I don't know what is wrong with my motherboard so I came to you for a diagnose.
