POST test troubleshooting

[rajmccurry]

Before putting all the components in my case, I did a basic POST test outside of the box with only the core components (motherboard, RAM, CPU, PSU, GPU), with the motherboard on the non-conductive box. After shorting the pins, the "system" started up all right, and I turned it off with the PSU switch after it reached the POST screen. I wanted to test it again, but it turned out that every time I turn off the PSU using its switch after POST testing, it trips the outlet circuit and I need to reset the circuit breaker. Only then can I test again using that outlet. Is this normal since i'm not using the front panel connector yet?

No, that's not normal. What PSU do you have (make and model)? Are you still able to return it?
