On my motherboard, I have my 20+4 pin connector is in completely and no response from the PSU. I have checked the PSU to see if it works with the paper clip trick. Sometimes when I wiggle the 20+4 pin connector in the motherboard, the power supply will turn on but no sign from the CPU fan. I also have a 8 pin split connector in the 4 pin on the motherboard. Any suggestions?
