Question Why exactly is sudden power loss so bad for PCs? is it just the threat of data corruption, or is there another worse consequence?

[Order 66]

I am also wanting to know what issues sudden power loss can cause.

Im partial to Tripplites products. They have never failed me.

I use the "commercial" APC line. That is the "Smart UPS Online". They are double-conversion, meaning they ALWAYS create AC from DC so the output is constant.

yes, but why is this one so expensive, and what is the point of having 16000W? Not that I (or many people) have the budget for this, but would it be compatible with a standard desktop? (I know it sounds dumb, but I know basically nothing about UPSs.)

how exactly does a UPS work? I know that it is essentially a battery backup for a PC but that is the extent of my knowledge.

Basically, thats it.

It provides enough battery power to allow the system(s) to run for a little while and/or shut down gracefully.

It also corrects under or over voltage from the AC line in. Basically any time there is an issue that could cause problems with electronics from the AC line-in it switches over to battery to protect everything connected to the specific ports.

so if you had a PC drawing 1000W and a 10,000W UPS, how long could the UPS last? Also if a PC draws 1000W, does that mean it draws that 1000W in one hour?

Here is the calculator from APC. Play around as desired.

I remember when I was in the middle of gaming, in the middle of a storm, next thing I know, the power goes out. I ended up losing about 2 hrs of the Star Wars Fallen Order because I was unable to get to a meditation point and save before the power loss. So frustrating, and I don't even know if a UPS would have helped since AFAIK Fallen Order has no ability to manually save.
