External PSU shuts down the breaker

Hi! I have a Gold Note PH10 phono and just received the PSU 10. After I turn on the PSU, it shuts down the breaker in the house. I have tried to plug in without connecting the phono, same results. It was all right when I tried in a HIFI shop, and worked well, even connecting to the phono. I would be suspicious, but every single component is working good (with higher load also), except the PSU.
What can it be?

Try it on a different circuit in your house, If it still kicks the breaker, Take it back to the hi fi shop

 Sounds like a short.

Perhaps it is tripping a ground fault interrupter (GFI) circuit protector in your home while the problem is not a dead short that would trip the circuit breaker at the stereo shop if it did not have GFI protection.  In any case, I would not want something that is tripping breakers and raising safety concerns even if it "works."
