I've been diving deep into the topic of surge protection for UPS systems but still have some questions. It seems like the surge protection offered by most UPS units is pretty minimal—around 300J, even with some pricier models. Conversely, I see that budget surge protectors can go up to 1,000-2,000J. I've heard mixed opinions about using surge protectors with UPS systems, particularly that they shouldn't be overloaded with power strips. If I'm faced with the choice between a UPS with weak surge protection or a solid surge protector without a UPS, what should I choose? Specifically, would it be acceptable to use a single surge protector, like the one I found linked here, plugged into the UPS for my desktop computer? If not, what's the reasoning?

Most UPS systems do come with some level of surge protection. However, the protection level is usually pretty low at around 300J. In comparison, the cheaper surge protectors offer much better protection—sometimes up to 2,000J! So, it might be a good idea to add your surge protector on the UPS.
Honestly, I think it's perfectly fine to put a surge protector before or after the UPS. We've been doing that for years with various models and haven’t faced any issues.
Yes, UPS units typically offer surge protection, but it's not robust enough for significant power surges. If you're going to use a surge protector, plug it into the UPS, and you'll likely be better off, especially if your area experiences fluctuations in power.
It really depends on where you are and how stable your power supply is. In places like Western Europe, I've never had issues just using a surge protector, and sometimes not even that! So, a simple surge protector on a UPS should work fine for your setup, especially if you're not in a storm-prone area.
