We are building a new computer - the power supply is a cooler master extreme 2 750 / the setting on the back was wrong set at 230 - when it should of been at 110 / the system is brand new & never powered up / plus with the wrong setting - ni lights came on / nothing as if power neevr travelled thru the system / we have switched it to 110 / but still nothing - so, wondering if the system was damaged or we have more troubleshooting to do regarding the setup - Thank You
