power-supply

I am in europe. There was a switch on my psu that could switch the voltage between 230v and 130v (not 100% sure). In europe we use 230. I switched the psu to 110 and turned it on. Several sparks and a power failiure resulted, the psu was fried.

Can someone explain why this happened. I was assuming that because the system was using 230 and the psu only draws 130 it would be safe cause it's less. I guess i was wrong.

Can someone explain me the physics behind this.
