The chips we make are designed to run continuously for 20 years. Nothing is certain. But this is a good quality supply. Odds are good it will be fine. There was a bad batch of capacitors out of Taiwan a few years ago. I suspect my hubs died because of that. But that is unlikely to repeat. > With today's hardware I would > NEVER guarantee a system to run solid for 5 years unless it was > high end and the manufacturers of each component were willing to > offer a least a couple years on each part. To *guarantee* you have to have very good odds or you lose money. My odds may not be that good, but they are good enough. > So with all the electromigration stuff does it affect the water > running through my systems? :) > > What chipset on your flakey Abit board?
