I recently destroyed the power supply on my computer. There was a 2 prong outlet that I used a 2 prong to 3 prong adapter on (this usually works by using the screw of the socket as ground). However, the outlet turned out to have the live wire and neutral wire swapped. This 3 prong adapter allowed me to plug in my surge protector, which the computer power supply was connected to, into the 2 prong outlet. After a minute of being plugged in, and without me even turning the computer on, sparks started spewing from the power supply, rendering it toasted. An electrician came in and tod me that the swapped live/neutral wires resulted in the damage to my power supply. However, other people I have asked have said that reversed live/neutral with AC current cannot possibly damage the power supply. I trust your wisdom very much, so before I make a claim to cover the damages to my landlord, I wanted to ask you this: Who is right? Can a reversed polarity (swapped live/neutral wires) in an outlet damage a power supply?
