How to protect your PC from problems with the power supply?

Question

Power Supply

Now I use FSP 450PNR, I learned from friends that FSP seems to be a normal manufacturer and with a calm soul I took this PSU from my hands. And now somehow I read reviews on the network, and many do not like it). Recently, I have been reading about possible problems with the power supply, when it fails, and other components go with it.
What is the essence of the question:
After some time, I will update the PC to more up-to-date hardware (later I will need a more powerful PSU, and in general everything is more powerful) and it’s somehow scary to lose all this. How to choose the right PSU to be sure that with various problems with the power supply and in general with hard work, the PSU will not ruin the entire system? Is it worth looking in the direction of uninterruptibles? Which of these would solve the problem better?

Answer 1

The interrupter won't help.
Some BIOSes have a function to turn off the PC if the unit outputs an abnormal voltage.
And so, the best defense is not to take marginal PSUs, but only from trusted manufacturers.
But it's still not worth it to drive - in fact, problems due to power supply are rare.

Answer 2

Yes, everything is fine with the FSP brand. For deshman, they have a separate Qdion brand.

How to choose the right BP

A good PSU is a dead PSU , a heavy PSU. In light, they saved on details.
In general, be guided by such thorough reviews, where there are voltage measurements and photographs of the insides. Simple reviews [supposedly buyers] are worth nothing today, there are heaps of custom reviews around.
I won't recommend specific brands. There are many normal ones, I'm not a fan of any brand.
Do not chase modular ones, here is a scary tale about modular ones (you can tell around the fire at night, you can scare small children): What will the HDD be like if + 12V gets on all SATA lines?
Here is another fairy tale about the modular, here at least with a happy ending (but it could be otherwise): The processor with 4pin power turns on, with 4 + 4pin the power supply goes into protection, how to fix it?

Is it worth looking in the direction of uninterruptibles?

If there are frequent power outages (including frequent over or under voltage, not just blackouts), then yes. If there are interruptions once or twice a year, the voltage is within plus or minus 5% of the nominal value (now the nominal value is 230V), then, well, what the heck is a UPS.

Answer 3

Buy a good power supply. Before buying, google a specific model, read reviews. There are also various kinds of lists by quality level, like this one: https://www.gamingscan.com/psu-hierarchy/
It can also be useful.

Answer 4

My stats are from around 1998.
In the company (from 5+ people to 20+ in the central office) there was one single power supply failure that took the insides of the PC with it (mobo - I definitely left, for disks - I don’t remember, but it was a computer from the head of the IT department, which by default means the presence of a working backup). The rest - either did not turn on and got to me for repairs, or were suspected of producing glitches and fell into the PPR (scheduled preventive maintenance).
At home, since 2002 (?) - one failure (on duty, without consequences), one replacement of the PSU (simply because a PSU was formed with a noise killer) and a PPR of this PSU when replacing the internals of the PC.
As for "bought used", then look at the pictures for the word " bounce rate". The initial period for the PSU is mainly defects in the assembly, components and circuitry. The final period is the wear of electrolytic capacitors, defects in the circuitry and topology of the printed circuit board (intentional "heating" of capacitors).

Answer 5

Voltage stabilizer will solve all problems with the network
