| 437004 | 2006-03-09 16:21:00 | i just bought a new p4 motherboard, 400w power supply and p4 processor. i put it all togeather and it started up just fine, but the monitor wouldnt turn on, so just out of curiosity i switched the little red thing on the back from 115v to 230v. so i turn the computer on and about 5 seconds later it sparked and cut off. I tried turning it back on but it wouldnt work. my question is, did i fry the power supply? i didnt see any smoke. another question is, did i damage my motherboard or processor in any way? one more question is before i started changing anything out, should i have installed the new motherboard software and then switched over to the new one? any help would be appreciated. i spent over 350 dollars and i would like to know before buying anything new. |

| 437007 | 2006-03-09 23:02:00 | Switching from 115 volts to 230 in a 115 volt supply system should not fry the power supply if it was properly designed, but it certainly will if it didn't have 'low input voltage" protection because the internal currents would virtually double in an attempt to produce the required outputs . The alternative (switching from 230 to 115 on a 230v power system) could also be safe in a properly designed supply with adequate over-voltage protection, but that is less likely and would probably kill it . However, it certainly sounds like you have killed this supply, and it is difficult to understand why you would switch the power input when the monitor is powered from an external source . I guess you won't do that again! Cheers Billy 8-{) Edit: You could take the cover off the PSU and look for the internal fuse, and if it is blown, replace it . That may have produced the "spark" you saw as it blew . You could get lucky . |

| 437008 | 2006-03-09 23:11:00 | I did the same thing with a mobo I used to have . The mobo was dead . I had to replace it . The PSU / CPU were fine . I'm still using them . |
