Yes at the moment it's running. Haven't dared to turn it off yet in case it doesn't start up again! LOL

The original PSU was changed by Philips during warranty but the one that I have just replaced appears to be HIRPO - 300 w.

The replacement I have put in is 500 w.

So this is the third PSU in that computer?

What happened with the first one?

Yes it is the third one. The original one got very noisy, they came and tested it and replaced it. Must have been over two years ago now.

And then the second one become very noisy?

Did the computer work OK despite the noise?

Yes, the computer was fine.

All seems to be ok today. So far anyway!
