Thank you,

It doesn't work great by plugging into the other wall plug because where it's connected right now is a dedicated line from the panel. Only my Pfsense box and computer are connected to it so I have to daisy-chain. The speaker, monitor, etc. are connected to another line.

As a rule of thumb, you should always connect your monitor and PC to the same outlet, just to avoid ground loops. your monitor's power brick "or built in power supply" also has a ground pin, both your monitor and PC are connected via either a DP Cable or an HDMI one, and both of those cable carry their respective ground to the other end of that connection and vice versa. And unless your speakers are connected via bluetooth to your PC, then they also need to be on the same outlet since audio cables or USBs also carry the ground signal.

So in general, just try having grounded electronics that are interconnected between each other on the same outlet.

Thanks for the information. Just trying to understand here, since my computer and Pfsense box have ground pin on each. How can I know if I have ground loop issue?
Or you mean since my monitor is connected to a different line, he could carry something else to my computer via DVI connection since my PC connected to a different line?

Yes, if the monitor is on a different circuit, there could be noise in the ground wire.

I really doubt that you have a DVI cable, unless its on your Pfsense? Anyhow, DVI cables are shielded and do carry ground too. Just make sure that whatever is interconnected with each other are placed on the same circuit.

Get the Corsair HX1200 2 days back with new mobo - no improvemnet for me DC blocker on the way so we will see

i have the corsair hx1200 since 2 years now, no improvement. i tried rrecently DC blocker, again waist of money for me it is worst...

Still struggling to find a fix

Which DC Blocker did you try?

Sry for the late answer, it was the IFI DC Blocker, tested for few days but can say right after plugging it that it is worse with than without.

Sorry was late, I meant Display cable. Since I have 2 monitors connected to my PC, I should have both on the same circuit? Correct?

That would be ideal yes.

Ok, I will try that! So the rule of thumb is anything with power that connects to my Motherboard or GPU needs to be connected to the same electric circuit.

I also have Camera Sony 5100 that uses a dummy battery to be always on and connect to mini HDMI to USB. should it goes to that same circuit too?

My speaker is Bluetooth by the way at this point

Not anything that needs power specifically, if EMC regulations required that electrical unit to have a ground pin PLUS that electrical unit is connected to your PC through a USB, HDMI Cable, Display Cable, Audio Jack, and/or "Shielded" ethernet cable, then the best practice would be to connect them to the same wall outlet to avoid Ground Loops.

You don't need to worry about that outlet's wiring amperage capacity either, usually in the US, the standards are met with either 12 AWG or 14 AWG electrical wiring, which are 25Amps "3000watts" and 20Amps "2400watts" respectively. That said, unless you are planning to mine with five 4090s you'll be okay.

Thanks for the advise, I did the change, not saying much difference but I'll keep it this way

I received the Furman PST-8D and the noise reduction with both filters is the same VS a regular power bar.

Regular power bar + 2 filters even get a little bit lower mV around 12 vs 17 on the Furman PST-8D. Now when we talk about noise once my PC is on, it remains the same, I guess I will order 2 other filters just to play around

Just to give a quick recap for anyone who just got here

My line noise is usually around 90-200mV while my Pfsense box and PC are OFF.
The noise emitted by my computer was at 1500mV, then I replace my PSU from Corsair HX850 to HX1200. This reduced the noise on the line to 600mV. Since my mouse became more responsive. I ordered two Greenwave filters and now my line noise in my office goes down to 12mV when the Pfsense box and PC are OFF. With 2 filters plugged in, now the noise emitted is between 80-120mV when both devices are ON.

So far my game experience has been good. My mouse input lag has been away since I started changing my PSU and now I'm just trying to make things a bit sharper. I will return the furman power conditioner.
