No, such an analyzer will not suit us.
You need an analyzer that shows frequencies from 50Hz to 1MHz.
To combat harmonics are suitable:
1) online ups
2) inverter voltage stabilizers
3) isolating transformers
4) network filters.
Online ups and inverter regulators perfectly suppress harmonic distortion and have no more than 5% distortion at the output.
I will be testing these devices soon.
This analyzer shows all harmonics up to 31. So its 50, 100, 150, 200 Hz roughly up to 2khz. More professional fluke analyzers shows up to 55 harmonics, but it still not mhz range.
Further it from base frequency amplitude is lower, so 31 harmonics is ok.
Online ups is definitely not working, its tested almost by everybody here, just search by forum.
Network filter doesnt work too, I have lowpass filter and its doesnt do anything. However on graph we see that its working in same frequency range, but no effect.
Isolating transfromer is on delivery, few days and will test it.
So probably its not harmonics. Or you need to take measurements in confirmed place without lag and compare it with confirmed place with lag.

The dedicated circuit did not work, Interference from the other circuit is still impacting this new circuit from the same panel. Now I guess I need to filter the power and make it clean!
It was obvious because even with dedicated circuit you still connected to same power source. Why you thinking its interference from other circuit, but not from other street/district circuit?

Because when something from the original circuit is running (dimmer switch, microwave, etc) the noise interference is getting transfert to the new circuit.

Your circuit connected to another bigger circuit and "noise interference is getting transfert to the new circuit."

So far by changing the PSU, and getting the EMI down to 500mV and it's been a week or so, my input lag is gone at the moment, the thing that is remaining is the desync in-game. I'm still to look around getting something to clean the dedicated line

Feels promising. Voices in my head are telling me to grab my wallet and get that Seasonic titanium 850w.

I have it, no fix. But I replaced mobo /psu to top tier components and pc had no lag for up to a week then it started to lag again. I have a good eye to spot these things cuz I have done over 40 windows reinstalls and played csgo without lag, it’s an absolute steal that we don’t play like that 24-7.

Will I get any benefit from AC Power Filer / Power Conditioner?
power filters don't correct voltage swings in the upside or downside. They simple attempt to filter noise. Your PSU/MOBO typically does this really well (not saying there isn't room for improvement). You may benefit from it but probably not unless you have god awful equipment. What you would benefit from is making sure you're getting a constant stable AC voltage being fed into the equipment.
Voltage fluctuations are not the cause of input lag. The main reason for input lag is the high level of harmonic distortion.
Do you think your motherboard is safe from this? No. Harmonic distortion passes through the power supply, weakens, enters the motherboard chipset and disrupts its operation.
Various errors appear in the chipset.
After that, the error correction function is enabled. This function causes the input lag. The error correction function delays the signal from the chipset to your usb devices.
This function is similar to ECC ddr.
I measured harmonic distortion right inside the computer using a sound card and found out that during the day (13.00-23.00) there is about 15-20% harmonic distortion in the electrical network.
At night, the level drops to 10%.
This is why the computer is more responsive at night.
This is the absolute TRUTH my fellow victim !
