Does crappy quality power from an outlet put more stress on a power supply?

post #1 of 2
Thread Starter 
I've lived in places with good clean power that doesn't dim the whole house every time you turn an appliance on, and I've lived in places where turning on a vacuum dims the lights for a significant amount of time. Does power from the wall with frequent extreme fluctuation cause more stress on a power supply than a clean steady voltage?

Well, yes, but it's of no consequence if the fluctuations are within what the PSU is rated to be able to handle.
