First check if you have the L/N/G cables correctly connected,then check the 110V/220V switch on the PSU.
This I already did with first malfunctioning and second malfunctioning psu.
The next move is to unplug the board from the PSU and measure the AC input and DC output with a multimeter.
Do I measure the PSU or the Board? (How and where do I do that with my multimeter)(And does it have to be on or connected to the electric network?)

I mean the PSU(remember to unplug the board from it).
AC input is the voltage between "L" and "GND",check this post:

Hi Guys,
My PSU work only one day. Today it doesn't work. The Green Led is off!
I'm Italian and we have 220V I see inside the holes and I see the switch is correctly set in 220V.
So why it doesn't work??? I have read of many people who complain about this Power Supply Unit issues!

Maybe the PSU is dead.
Just replace it with a new one.

Yes the technical support reply to me in PVT by email. The PSU is dead! So I would like to let you guys that me and a my engineer friend measured the current absorption with a current meter about the Prusa i3 MK8 and we've seen that it is higher than the 15A delivered by the PSU. The supplied PSU is underdimensional!
