Check the CPU heatsink bottom plate (If you are using a custom heatsink). It could be shorting to the mainboard. But, that short doesn't become apparent until the mainboard is bolted to the case. Happened to me once.

You could also have a bad PSU. Is it new?

The PSU could be "good" but have a short to ground. I've seen several with that manufacturer defect. Only fails when bolted to the case.
