[QUOTE="enafuit, post: 1380676, member: 239811"] After trawling the web for weeks I came across this. Although my problem isn't solved as my Mac Pro is away being repaired. So I don't know if this will solve my problem but it is very interesting. [url=http://www.ifixit.com/Answers/View/27167/No+Power+on+Mac+Pro]No Power on Mac Pro - Mac Pro - iFixit[/url] "Do not replace the power supply unless you have the original system installation disks as they contain a program for syncing the fans. If the sync is not done the fans will run wild. " This could be the reason for my 3 PSU failures. I'm very surprised that this has not been flagged as a major issue by Apple or the sellers of Mac Pro PSU's (which there are quite a few). [/QUOTE]
