anyway, that all is same, just unplug ups, and if you not feel instantly fix, that is not socet, because in another apartment same pc with same psu work perfectly.

Chief, close forum.

No one said it´s the ultima fix.
Are you sure the "apc smart ups" was online and NOT line?
There exist also line versions on the market.

I won't recommend anything that doesn't work.
trying 3 different ups with double conversion + toroidal isolation transformer with virtual ground. + 100500 types of filters.

Which UPS have you tested?

u never fix it by socet filter

I see, anyways I think that's too much schizo, I try to focus on plausible things that can be proved/fixed, if we start searching for interference in the air we would never fix the issue.

Interference in the air is easy and cheap to fix with faraday fabric.

ups cant fix air


Air? We are talking about filtering dirty electricity


That what he means:
Harmonic interference transmitted over the air is caused by high switching frequencies and wide frequency spectra, which propagate like radio waves and are particularly relevant in building ...

ups cant fix air


Thats why i have covered everything with faraday fabric. I had covered my PC and router before I had a PSU but im not sure, if it made for me any difference...
This is the ultimate test, is the input lag/desync problem electricity relaited or not.

The filtering in a VFI-SS-111 ...

Since yesterday 26.11.2025 i am doing the same test. I have the Riello Sentinel PRO SEP 3000VA.
Also with the VFI-SS-11 (EN-62040-3) specification. This specification is very important. PC, PSU and router are plugged in PSU and covered with faraday fabric (I gone crazy :roll: ). I made about 6 games ...
