I was building a new PC today and everything went smoothly, but after i had ran the PC for about 30 seconds it turned off and i couldnt start it up again. When i press the power button my PSU starts the fan for a brief moment, does a werid clicking sound (that ive never heard before) and then shuts off. It sounds to me like there is some kind of short circut in the PSU itself or some fuse going off. I tried putting everything apart and together again and made sure everything was correct and it still didn't work. I also tried the paperclip method and the same thing happens, power on, click, dead.

Did i do something wrong or is my PSU actually broken?
