I have a question with my power supply. I use the paper clip test on my PSU. its providing power but the PSU fan is not spinning. I know it's providing power because I did not remove the HDD cable and fan that connected directly to PSU and my HDD is operational and the extra fan (not the CPU_FAN or SYS_FAN) is spinning. But when I connect it properly to the motherboard (everything), there is nothing. No LED, HDD, any FAN whatsoever the computer is not turning on. Do I have a bad PSU if the PSU fan is not spinning or motherboard problem? Help.
