Here is your video: https://photos.app.goo.gl/VX4djNxnyFu3rogeA

While my PC is running, the EMI reader gives around 1480mV, when the iron (set to high) is plugged in, it reduces to around 1300mV which is still high.

One thing to note is that maybe other kinds of Iron are powerful enough to significantly reduce the EMI from the circuit, however from my own issue, this won't help because let's say I had an Iron that will reduce the EMI from 1480mV to 200mV. Only all devices connected to that outlet will have less impact from the EMI emitted by my computer, but my computer still generates EMI on the other way.

My goal is to fix the EMI that is generated by my computer which so far it's mostly generated by the PSU.

We have to undestand that these PSU are for sure OK there is 0% chance that you got two PSU that emiting excesive amount of EMI just because thats not how this works…
I was lately talking with ppl wich and they are addicted to audio same like we do to the gaming…
They allready know that PC (most likely PSU) is emiting huge amount of EMI. They says that any switching power suply will do that if the input is bad most likely DC power in the AC system.
I am allready in proces to test all these things but my PC is in the waranty send back if you know what i mean.
MOBO- dead sound card - MSI Z790 A Pro DDR4 (1 month old mobo)

To undestand that nothing is wrong with your PSU is that there will be way more ppl with same issue like you or i have….
They explain me clearly that toroid filters get infected quickly if DC ocurs in AC system. These filters are in all PSU they small not realy build to stand DC current. I was testing big toroid filter there was for sure improvement but again lag come back.

You look like dude that realy dont care what will take it to solve this issue so pls take advice from me and stop testing other PSU there is nothing wrong with them…
I am realy sugest you look for ifi DC blocker you will have two week advatage on me.

something for read:

https://ifi-audio.com/products/dc-blocker/

DC blocker was tested already by dozens of people. No lasting improvements.

Dervu, do you know which DC blockers they did use by any chance?

Multiple manufacturers. Not worth listing them, because all of them are enough to block DC, that is usually not high, and they use same principle. Some people used same one as me, some used others. There are tons of them to buy, doesn't really matter which one you use unless you get to some really high levels of DC. Some block up to 1.xV like mine and some 3.xV.
For example I used Tomanek DC blockers.

Did you test hx1200i right or it was that rm850?
When i see video like that dark room and that EMI test good know where is connected i do not 100% belive them. (sure i am not that sceptical they probaly legit thats why i give i try that seasonic)
If you post video where is outlet, iron PSU i 100% belive them.
But if he say so i will get that seasonic PSU (i do not like corsair PSU - its personal) for testing even i do not belive in any improvement.

I own- BQ straight power 11 750 gold
- EVGA 750GS gold
- BQ 400W system power 9 bronze
- seasonic 550 gold

They all same, non of them high end so i will give i a try to that seasonic that you post but results will be after my mobo came back.

Nothing against Poland stuff but they do not excel in electronic i will for sure not buy Tomanek and give i shot to that ifi if there will be 0 improve then next will be ground loop isolator and then who know….

Pls man try same thing with that new PSU but connect iron to same outlet the numbers will be interesting…

DC blocker was tested already by dozens of people. No lasting improvements.

I'm actually also looking into investing in a DC blocker. And I don't think that anyone have tried it extensively and reported back we know that a lot of people have tried PSUs, Conditioners and Filters. But I don't remember a single post about A DC Blocker being used.

Coming back with some tests done and some interesting things to note

Test 1
- HX1200 received and after testing the PSU, it's emitting 580mV
Video: https://photos.app.goo.gl/nG6JRoTcBGjVDiLk9
I'm not getting near to the other results from the other videos I posted earlier. I noticed that my mV was already around 170mV before the PSU ran it's because the light dimmer in the living room was on! Once it's off it goes back to 70mV. Even if the dimmer is off the results remain the same for the HX1200 on my side.

The interesting part is that I did install the HX1200 in my computer for a test run and it's giving me around 500mV and sometimes down to 400mV. First of all, it's 1000mV less than the HX850 which is great. Finally, there must be something going on, potentially DC current present in my AC

"What I noticed when testing is more responsiveness of my system, the mouse feels a bit shaper and I noticed that in Valorant for example in the range I usually have 800 FPS and now it's fluctuating to 950 up to 1000. Interesting!"

Test 2
- I decided to remove completely the HX850 from my computer and tested it, resulting in 350mV. This is lower than last time which was around 700mV but it was in my computer case with all cables plugged in except, Motherboard, GPU, and HDD

However, when I plug everything back into my computer the EMI line meter will read back 1500mV

Test 3
- Since I still had the HX1500i with me, I decided to run it on my computer and the result is the same as the HX850 but a bit lower around 1100mV
Video: https://photos.app.goo.gl/jWy8wJqVqPJ1uMg7A

Conclusion: The HX1200 seems to filter something better than the HX850 and HX1500i

Maybe the next step is to find DC Blocker and test it live video?

can transformer reduce it ? from 110v to 220v or 220v to 110v

That make sense to me did you test it yourself?

I was wondering too but i think still you need DC filter and then step down or step up voltage regulator thats what i bin told…
