I have a Rosewill Lightning gaming power supply, specifically: http://www.newegg.com/Product/Product.aspx?Item=N82E168...


This thing doens't say which side is the 115 or 230 setting. The switch actually has 3 settings. Left, Center and Right. I don't know which position it should be in. Any advice?

What happens if I get this wrong?

If you get it wrong the power supply explodes. That PSU also has active PFC so it shouldn't have a voltage switch, i believe the switch shown in that picture is for the fan color.


What country are you in?

If you are in a 110-125V country, setting the wrong position may do:
- nothing
- PSU works but likely at reduced efficiency and reduced margins to cover brownouts
- PSU blows its fuse or possibly more

If you are in a 220-240V country, setting the wrong position will:
- almost certainly blow the fuse
- possibly destroy the PSU
- maybe damage computer components if the PSU rings its outputs faster than it can blow itself up

So the wrong position in a ~120V area is relatively safe while the wrong position in a ~240V area is almost guaranteed to blow something up.
