I already tried to adjust potentiometer, nothing changes.
and I've seen the 110/220V switch, it is in the right position (220V)

I'm sure the power supply is broken. I post a message here only because the vendor ask me to do it but I know the only solution is to change the power supply ...

Hello,

I received my printer last week but there is a problem with power supply.
It supposed to deliver 12V but actually it only deliver around 6V.
I tested it with no load (without plugin it to the prusa)

I think the power supply is broken.
