How secure are computers against sudden power cuts?
I live in a city with unreliable electricity, where sudden outages are common. What concerns me most is the possibility of power fluctuations occurring five times per minute. I usually keep my PC off until it stabilizes, but I’m not entirely sure if this is safe. Could this real damage occur, and how often does it happen? How effective are modern PSUs and other components in preventing such issues? I’m thinking about buying a surge protector soon. Someone here might know something about PSU protection or similar solutions.
Heres a thing,people tell me i should get UPS if i do a lot of data transfer and such (which i dont,i just do gaming and basic stuff like watching youtube,movies etc),and get surge protector instead for the problem i have.
I once built a new machine and connected my HDD. When the power went out, the HDD stopped spinning and then came back on after a couple of hours. Before it finished, the power turned back on again. Since then, I've adjusted my BIOS to prevent it from rebooting after a power cut. Now I just let it sit, do something else, and come back to it later. It works for me.
A working UPS will potentially save data loss for what you're working on at the moment (i.e. the document you're editing right now). A power interruption will cause you to loose this data - or if you're lucky the program save recovery data each 5. minute so to minimize the data lost.
I said lucky, because we never know if the OS file system truly have written all data to disk before interruption occur.
However - if the power interruption also includes seriously voltage spikes (yes, I've seen the effect of this in real life, real time) - then there is always a potential risk that components other than the PSU takes damage.
In this case, I'd advice using a actual backup using an external storage device, in order to be less prone to component failure, ransom ware, etc.
Forgot to mention: An UPS will function as a protection barrier against voltage spikes from main, so it's much better than nothing. But doesn't replace backup in any manner.
What I suggest is a reliable option that balances performance with affordability, ensuring your PC remains stable and you have sufficient time to shut it down safely. Your PC specifications are listed in the first post.
