Which computer power supply produces little or no dirty electricity?

Marc you mentioned RF absorption material helps reduce a computer's EMF.
 I'm always looking for ways to reduce my computer's EMF. How can I find out more about your technique(s)?

> Marc you mentioned RF absorption material helps reduce a computer's EMF.

Well I don't have much experience in this, but I recently got stuck with an intolerable "work at home" PC, and I'm trying to find good ways to make it tolerable.  RF absorption materials is one thing I'm using currently.  From MAST Technologies, Reticulated Foam Absorber 1.250" in 24 x 24" squares.  Expensive, and not yet sure where it falls into the effectiveness category, as I'm doing all sorts of things at once right now, and will gradually take things away to see what's making the most difference (as the PC is totally fine with what all I'm doing now, but I suspect I'm doing way more than is really necessary).

Based on my experience, it seems that the computer's power supply is not what causes EMFs, what causes them is the home itself.

I have lived in many homes, always using the same computer. Some places just seem to have strong fields running through the power sockets, and when I plug things in, there are large fields around them. Other homes, the fields have been inexplicably lower.

It's the same with my electric piano keyboard, I love playing but I had to quit playing a few years ago as the huge electrical fields were hurting my hands and I felt sick when I used it. But the field varies based on what home I lived in. In some places, the fields were very low.

Am I the only one who has found this? That it's the house, not the appliance?

I probably shouldn't even be on this post but I'm impressed with everyone on here, the knowledge they share about the subject! And since the post started in April possibly no one is watching it now but I'll post this anyway!

This is kind of for Marc because he mentioned about Dell computers and distance from the user and the grounding sheet for mattresses.

I have my 4th Dell and if I move it say 9ft away will my keyboard and mouse stop burning my hands and fingers? Wired keyboard and both wired and wireless mouse both burn my hands and fingers.

About the grounding sheet. I purchased a, what looks like a sleeping bag, which can be totally opened up and fits on a bed. It's called RF Protection Blanket/Sleeping Bag and I purchased it through www.4EHSByEHS.com I don't know if that's the same thing as or like a grounding sheet or not but it does nothing, provides no protection from anything. I've purchased things from Earthing that didn't work either. Any suggestions where to purchase articles like that that protect?

Thanks greatly for any suggestions!

Kay, the grounding sheet I am using on my work PC is the Earthing brand, I believe.  I just kind of loosely put it around the PC and plug the wire in a nearby outlet.  

As for whether that will help a specific person, impossible to say.  I already had a monitor, keyboard, and mouse that I know I tolerate with other PCs.  Plus an internet connection that works fine for me.  So the only real thing I had to "fix" was the PC itself.

Plus I own all manner of "EMF protection devices", which are also in use.  But I already had these as well.

I too have bought quesitonable RF shielding material in the past that didn't work, even though the store owners seemed very genuine.

But I recently bought  RF shielding material that WORKED from this site: https://www.lessemf.com, so I would recommend them. The site is a little clunky and often too technical, but the guy I spoke to was helpful in advising me on what to buy for my budget (some of their products are way out of my price range, I am quite poor).

My mouse and keyboard burn my fingers too. I could be wrong but I don't believe distance will make any difference as the electrical field travels down the cable.

I have my computer a few meters away from my desk (using extension cables) and the keyboard and mouse burn just the same.

However, I DEFINITELY recommend having the computer farther away. Because it's not just the mouse and keyboard that burn my hands, but sitting near the computer itself affects my head and makes me feel drained, dazed and confused. I found that the further I sit from the computer, the better I feel. It's only subtle, but I can notice the difference. (Though that could just be my computer, not all computers?)

I still haven't figured out a way to use the mouse and keyboard without my hands burning. There's no way I want to use a wireless keyboard and mouse!

Well, the older the keyboard & mouse, the better.  My keyboard and mouse don't bother me at all, but consider this:

- they are both at least 20 years old
- they use PS/2 cables/jacks, not USB
- the mouse has a roller ball on the bottom, not an LED/laser

What relieved my aching hands when using the computer mouse was purchasing an older PS2 ball mouse.  They are available at LessEmf, sometimes on Amazon or Ebay, or search out the used electronics section in thrift stores.

If I attempt to spend a considerable amount of time on someone else's computer using their optical mouse or heaven forbid typing directly onto a laptop instead of using USB keyboard with a long cord, the hand pain returns with a vengeance.

I've tried using an older PS2 keyboard but it made absolutely no difference to the EMF levels - they're still just as high.

I can't use a ball mouse as I would be completely lost without the extra buttons my Logitech mouse has! I'm a buttons man!

Thank you to each one of you, you John, Marc, Fog Top, black-sun, who offered help and suggestions!😊 My keyboard is as old as dirt! Well, almost! Anyway, I will certainly be checking out all your suggestions!👍
