1. define what needs to be secured
2. how much time do i need to savely power off.
3. can the battery be replaced and where i get them(car batteries are the best case).
4. Where do i want to store it.
5. how much do i want to spend.
these are private requirements. Companies need at least two(each device gets connected to both) and in some cases an diesel generator with an black start function. -
@stop uh... This is a personal desktop. Just want it to not shit of whenever the power goes out

@billgates use your maximum of your psu in watt.
Use it with the triple of your usual complete shutdown.know you have the minimum VAm.
round it to the next 100 VAh.
1000W * 3 * 5 m = 15000 VAm = 250 VAh -> 300VAh
i cant give you a tip on us-sellers, because i am used to the european "i must prove its save"-measurement, BUT amazon wouldnt be even my 100rds choice.
It must have replacable batteries, the replacement must be doable by yourself and you should be able to replace it while its online. -
@stop Amazon is just the seller, I need decide which brand and model which seem to come down to APC or CyberPower. All have replaceable batteries but all always have bad reviews...
There are no 5star models and again I don't want anything destroying or burning down my computer or apartment... And yet that seems to be a possibility
Per my previous rant, I'm reading the reviews for different UPS units 800+ VA/400W) and am looking at this one particularly after going through a lot of them but they all seem sort of mixed.
https://amazon.com/dp/B000QZ3UG0/...
Lots of failures, burning smell, Sparks, and not honoring damages or that they can actually destroy the PC rather than helping it....
And for this brand, another issues send to he AVR vs PFC... Don't know which to get except PFC is $20 more...
I just don't know anymore, sorta like I'm screwed if I do and screwed if I don't...
How do you pick which UPS to buy and make sure it doesn't burn the house down?
