I currently own a SeaSonic M12II 620 Bronze 620W power supply and tried to get my pc to post which failed. No debug LEDs lit up and the PSU clicked once. Then I tried shorting the pins on the motherboard which also resulted in the PSU clicking once. So I tried putting a paper clip in the PSU motherboard connector and when I did that it was followed with a single click. Can somebody tell me if I'm doing something wrong or if the PSU is defective?
