Is there any way to test the 'cleanliness' of the power your are getting at your PC from the UPS and also from the wall?
I have a powerful workstation (Dell T7400) that is now on its 3rd PSU in 30 months (all under warranty thankfully), but 3PSU's seems like a lot to go thru in 2.5 years, especially given that I have owned over 20+ machines in the last 15 years and never had a PSU fail on any other machine.
I have a 10 year old APC SmartUPS 2200NET, (now on its 2nd set of batteries), but I wonder if over time they start to give off 'dirty' power that maybe contributing to the premature failure of my PSU's? I don't know enough about elextricity to quantify what I mean by 'dirty' power, but the dell tech that swapped out my PSU's suggested I may want to look into it.
I just bought a newer, (expensive) workstation I to be honest I am afraid to plug it into the UPS, but at the same time don't want to drop another $500-$1000 on a UPS without a need.
