For the past few years I've had the Core i5 750 running quite happily at 3.6Ghz, until i decided to see if I could go for 4Ghz.
Boot it up, no problems, then after 10 mins of stress testing with LinX the computer just turned off, then back on for 10 seconds, then off again :S
Upon testing discovered that although the PSU was putting out voltages within spec under no load, the power good wire was at 0V preventing the computer from booting.
Purchased an XFX XXX pro series power supply and everything is working again, but I'm intrigued as to why the power supply would have suddenly failed.
It was an OCZ 700W power supply so it's not like I was trying to push the limits of what it can provide, nor is it a cheap no brand PSU. The voltages all showing correct is interesting, I wonder whether it is just something in the monitoring circuit that has gone but everything else still works properly, or perhaps under load they would stray out of spec now.
