That's true. People want crap, they get crap. :-) > Additionally, are you sure your service power is good?

In Germany, we only get the purest power made of highest quality electrons, 230V 50Hz 24/7/365. :-) Note that I'm running this power supply for more than 7 years now - the SAME power supply. > Not a direct answer to your question, but hopefully some useful > information to consider. That's right. If you have the chance, monitor your power outlet, e. g. with a long term peak monitor or a scope with battery backed up memory, just to make sure the requirements of the PSU are met. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
