A friend of a friend has been working on my PC to deal with a long standing problem which he said he had fixed. When my son plugged in the power lead the PSU blew up. I checked the rear and found it had been set to 115v. How could the machine have been running at that voltage during the tests he was runnning? I tried a replacement PSU but the machine is dead. I assume there has been damage to the motherboard. Is it likely to be terminal?

Did you use the same lead?

Check the fuse., you may be lucky.

Yes - the fuse did blow and the PC now works with a different lead. Thank you! But am I right in assuming that the PSU blew because the voltage was set to 115V?

In a word - yes!

You were very lucky that the PSU didn't take out the motherboard CPU and or harddrives.

I suppose I have been lucky. Thank you.
