I worry about electricity quality and PSU/other PC components taking a hit due to electrical quality that is beyond my control.

Would you say that an online UPS would be the best solution to this issue? Online UPS units feed power from the battery always.

But I am just guessing here. If there was a benefit to online UPS units I would think more people would use them. I don't know anyone that does.

I don't run anything without a UPS. In my experience they are very common.
