Power supply troubles

when I set my atx power supply to 230W The system starts to power up, but just hangs before a ram check. My screen is black and I must reboot with the supply set to 115W. I dont think the problem is in the system, is there any way the power coming out of the wall could cause this problem, or does anybody else have any ideas?

Any help plz.

Chances are your system is OK. Do as jhance says and set the *VOLTAGE SELECTOR* to the appropriate setting for your part of the world and then LEAVE IT ALONE! It was probably set to the correct setting by whoever built your system.

The powersupply's are designed to shut down and prevent damage to your computer in the event of a high line (230V input on the 115V setting) or low line (115V input on the 230V setting) condition.
