Not all power supplies are created equal. Unfortunately, there's no government oversight on power supply ratings, thus a cheap 450W power supply might go unstable if it has to supply 200W for very long, whereas a good quality 200W power supply might be able to put out 450W for short periods reliably. Additionally, are you sure your service power is good? Even the best power supply will fail if you're not getting 120V/60H at the outlet (or whatever voltage/freq you're supposed to get in your part of the world). Not a direct answer to your question, but hopefully some useful information to consider. --=20 Bill Moran http://www.potentialtech.com http://people.collaborativefusion.com/~wmoran/
