Is there a list/chart to compare EMI ratings of different PSUs, the links in the previous posts seem to be for specific/individual PSUs.

I've used a Corsair RM850 in my build for a year, then switched a few months ago to a BeQuiet DarkPower Pro 12 (850W). I would assume a PSU with a Titanium efficiency rating would have low EMI, but who knows. I'll have to look into it now.

i have one fix for u yonaxsangi switch ur power supply with good unit with a really good emi filter like hx1200i or ssr-1000tr from seasonic looks the difference


good word about spread spectrum

spread spectrum is a hot topic of debate if it actually "works" it's just spreading out the energy some more. it doesn't reduce the overall power leakage
it helps meet the legal requirements, but the effect on actual interference is debated

sorry yonaxsangi the whole problem come from PSU

ax1600i Huge emi

hx1200i Extreme low emi

To kind of answer your question look at the below quote:

AX1600i as Titanium rating and seems to struggle with EMI

God bless your soul my man, you're doing good work! I remember Nawaf, he is the OP of the longest post in here haha. I'm not sure what happened with his inputlag issue at the end though..

An EMF reader really won't do you any good, I had mine and I kept testing stuff for about 2 weeks until i sold it. nothing really helpful came out of it. there was nothing unnatural going on under the desk, in-fact the readings were normal, unless I stick the device next to a working fan then it reads it's electromagnetic radiation. I did see that my desk had high reading on its frame and counter-top. I was able to find an unpainted screw-hole and connect a grounded alligator clip connected to it. the entire frame now was grounded and no more electric field detected on the metal itself, but the counter-top was made of compressed wood and there was no way for me to ground that.

Did you take a look at the seasonic titanium line-up? They should offer the best of that world, in terms of efficiency and quality of components used, but I don't know how its EMI emitting behavior would be like?

Another test while my PC is running.

When I tried the meter in the kitchen and the reading is 700mV instead of 70mV

Tried in the living room and the reading was 600mV

When in the basement tested in the living room, kitchen and both bedrooms reading was 400mV

When I turned off my computer all went back to normal.

Tried with the HX1500i and it went up again! So far something is going on with the HX850 and HX1500i

I found a video where someone is testing the HX1200 and not the HX1200i. I found one and I will order it for testing
