You are correct on this. My point, however, was that power conditioning is often overlooked or forgotten, and it is an important item to look at IMO. But for the price that a good, or even decent one, costs, it's not much more to step up to a UPS with this functionality. >> A while ago, I started graphing the readings from my APC SmartUPS, and >> the results are interesting to say the least.

Agreed. However, my kit would have been exposed to this if it hadn't been for the UPS. I'm glad that I started graphing it all. To make this on topic, considering the age of your typical G4 and the older designs of the power supplies (which may be getting up there in age), having good surge suppression and power conditioning is becoming more important as time goes on to help shield the hardware from stuff like this. IMO, there will be a day where replacement parts are hard to come by and doing what one can to extend the life is always a Good Idea (tm). -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
