Would a blackout harm my computer?

[mercyvs]

First of all, Excuse my bad english 🙁

Okay so, i've been with this question for a time now, I Live in Venezuela and here the electricity system is a little "unstable" And all day long there are overvoltages and under voltages, and sometimes blackouts and well, the last two make my computer turn off instantly. I want to know if these power off actually do harm to the computer in any way, and i have one of these...

I have the computer plugged in the one that says " AVG " And the Monitor in " Boost " Do blackouts and undervoltages/Overvoltages harm the computer? and if the answer is yes which is the best way to protect it from them

Just in case my specs are:

Biostar H81MLV3
Pentium G3260 3.30 Ghz
4 GB DDR3 Ram 1333 MHZ
A random generic 600W PSU

Thank you and again, excuse my grammar xD

if voltage is unstable, it may kill your PC (depends on which tier quality is your PSU)
as for protection, if ure on budget, u should get atleast power surge protector, if u can spend moneys go for UPS unit

And do not go cheap on the UPS.
Get an UPS with already everything equipped: voltage stabilizer, surge protection, etc.
Good UPSs should usually already have those.
You need a UPS with at least 600VA capacity which can hold at least 10 minutes of total blackout and has a pure/true sinewave output.
Where I came from, we also need such UPS or we have to replace the PC every other weeks.

The area I live in also has pretty unstable power.
There power goes down at least once a day.
On Monday the power went down and came back instantly like 6 times.

My PC still works so far. It's not the power loss that breaks the PC, it's when the power comes back. It may come back at a higher voltage and that may destroy your PC.
I've got an outlet with surge protection and overvoltage protection, also my PSU has various protections. So it should be safe.
