Hi John, You said that the problems happened when the system was under a bit of stress (high CPU load). I would trying using some of your spare PSU's under these conditions. You probably won't see the problems in the voltage under any system monitoring software (they may be of too short a duration - if they are occurring at all). You aren't trying to do a double blind placebo trial here.... You just want a PC that works!! (PS thats one way to define the difference between an engineer and a scientist :-) So just try out the other dodgy PSU's. If they haven't been used to much they should be fine. The cheaper ones do seem to wear out over time :-) Everything in your system depends on stable voltages from the PSU (RAM, MB and CPU) so it is the lowest common denominator for system stability!!
