Need help fast! Power Line really low voltage, 190V compared to the normal 220-240V.

Is it a risk for my PC to run like this ? What about other electronics such as my Smart TV ? Sorry if I got the category wrong, I didn't know where else to search since I can't find a definitive answer elsewhere.


Edit: forgot to mention that I have a line-interactive UPS, but others in my house do not so I'd like to expand my question by asking if there is a risk for my UPS to run on these values for so long, or my PC for that matter. I can hear it working on converting the voltage to a value of 230V that it displays on it, so I am somewhat safe. I think, don't know if that could become a risk.

I still need my original question to be answered since as I said not everyone in my house has an UPS.

Edit2: Some voltage values from SpeedFan and other software
Vcore1: 1.1 - 1.28v
Vcore2: 1.5v
+3.3v: 3.34v
+5v: 5v
+12v: 1.98 - 3.78v ----- checked the bios, it says 12.4v
-12v: speedfan shows -0.92, while other software -12.48v
-5v speedfan shows -2.14, while other software -8.45v
+5v 3.55v
Vbat 3.26v
 
Solution
Low voltage can be as bad as high voltage for electronic equipment. How bad depends on the quality of the power supplies in each device.

Assuming your in a country with a 230V standard you are about 17% low and the maximum low voltage should be about 10%.

It could also affect other electrical equipment like refrigerators, air conditioners, etc.

Contact an electrician and/or the power company.

Where I live any problems between the main power lines and the meter are the responsibility of the utility company and any problems on the consumer side of the meter are the consumer's responsibility.

Hi
The PC PSU will be fine as they normally are made to work on any voltage between 100 and 250.
Other electronics however may be affected,you should check each of them for the range of voltage that they will work on.
