Hi, i got a powersupply and on the back there is a red switch that can either be switched to say 115 or 230. its an antec 550w powersuply. im using it on a asus a8n sli board 7800gtx 2g of ram a hard drive and optical drive.

if you live in the US, it should be 115 unless you are plugging your computer into a 230 volt line (which i doubt).

urm, i thought that too, and switched it (while my comp was on), the powersuplly went out with a bang.
