IMPORTANT:
This subforum is for advanced users only. This separate area is for niche or unexpected lag issues such as electromagnetic interference (EMI, EMF, electrical, radiofrequency, etc). Interference of all kinds (wired, wireless, external, internal, environment, bad component) can cause error-correction (ECC) latencies like a bad modem connection, except internally in a circuit. ECC = retransmits = lag. Troubleshooting may require university degree. Your lag issue is likely not EMI.

Thread dedicated to building a pc that avoids EMI
Mention the best protective cases, the best power supply that create small amount of emi, best GPU RAM CPU and also if possible, pc building services who build the pc for you according to your needs. This means of you want to add ferrite chockes on the wires cables, they do it for you.

Hey, im interested in a post like this, did you find the "perfect" build?

Re: Thread dedicated to building a pc that avoids EMI
I never saw a ferrite core being putted on a power supply wires at least not on a desktop computer, but on laptops yes.
Also I have a razer krait mouse and it has a ferrite core at the end of the cable that goes to the usb port of my motherboard, but I was wondering why the do only put one at the end of the cable? For instance i have seeing different devices that have 1 ferrite core at the start of the cable, then at the end of the cable, why this rule doesn't apply to some devices?
Sorry for poor grammar, have good day.

Re: Thread dedicated to building a pc that avoids EMI
As a law, in theory and in practice, everything that have it's own power supply unit (which means everything that itself, is connected to the outlet) when we wanted to connect it to other component that have the same condition, their connection wire 'SHOULD' have ferite chokes on each ends, to stop whatever interference each one have, with each others.

So what if one of them doesn't have it's own power supply unit but simply powers by the other one to work?
Congrats, you guessed right, their wire only needs one ferite choke at the end of the one which is connected to it's own power supply unit.
Hope I explained it the way you understand.
Now:
aboveRule.replace(aboveRule, whateverIAgreeWith);
Means: I don't agree with the whole rule, and it should be replaced with whatever I agree with.
But it's just my opinion, and, it just doesn't matter, because I'm not a scientist nor a professional electrical engineer nor anything related, so it's just my app and its a messy unpractical one, BOOOOO

Re: Thread dedicated to building a pc that avoids EMI
Oh this make sense but still weird that the desktop PSU doesn't come with a ferrite core on cables that supply the DC voltage to components.loccomacco wrote: β02 Aug 2023, 13:27As a law, in theory and in practice, everything that have it's own power supply unit (which means everything that itself, is connected to the outlet) when we wanted to connect it to other component that have the same condition, their connection wire 'SHOULD' have ferite chokes on each ends, to stop whatever interference each one have, with each others.

Re: Thread dedicated to building a pc that avoids EMI
Yeah InputLagger is right, but PSU together with the help of motherboard, they not only have ferrite chokes, but also have a lot of other components and ways to get rid out of a large range of troublesome EMI frequencies, so they pretty much have everything and by knowing that, you can conclude why every other external devices that somehow filters things, doesn't do much to solve our problems.pcenthusiast92 wrote: β02 Aug 2023, 19:41Oh this make sense but still weird that the desktop PSU doesn't come with a ferrite core on cables that supply the DC voltage to components.loccomacco wrote: β02 Aug 2023, 13:27As a law, in theory and in practice, everything that have it's own power supply unit (which means everything that itself, is connected to the outlet) when we wanted to connect it to other component that have the same condition, their connection wire 'SHOULD' have ferite chokes on each ends, to stop whatever interference each one have, with each others.

That's why I'm saying, filters can not be the answer to our problems, but those filters from GreenWave have some other factors which may add some changes to our problems, but it totally depends on our conditions like do we live in a crowded areas or do we live in an apartment and so on and also depends on how we use them like where we plugged them into the wall, but after all still you may not get any benefits by using them, they are really a bet.
