Assuming you're in a 230V country, and you change the switch on the back of the PSU, your PSU will go bang and you'll need to get a new one.

Cheap ones without active PFC often do.

i have cooler master Elite V2 550W, on the back there is a red switch with the number 115, i'm in usa, my pc is working fun.
my questions: since it is currently showing the number 115 on the switch, does it means it is running on 115, or on 230?

Your PSU is on 115V.
