How To Stop RFI From AC To DC Power Supply

Do you hear a high-pitched noise coming from your power supply? This buzzing can be enough to drive even the most patient of people mad. If this is something you've been experiencing lately, you're not alone. Many people just like you hear this irritating sound, and despite all the attempts to fix it, it can be tough to find a solution. But don't worry - we're here to help address the problem with the most simple solution possible.

In this complete guide, we'll teach you how to stop RFI from ac to dc power supply. Not only that, but you'll learn what is causing that horrible noise you've been hoping to eliminate for some time now. After an in-depth explanation of how to stop RFI noise from your power supply, we'll teach you where to buy power supplies that never produce RFI noise. Because, spoiler alert - that RFI noise is caused by a cheap, low-quality power supply! The solution is as simple as replacing your power supply with a high-quality alternative that features RFI shielding.

Before we get into all that, let's start with some basic information - what is RFI in the first place?

What Is RFI Noise?

RFI, or radio frequency interference, is a type of electromagnetic pollution that can come from all sorts of electronic devices. In most cases, RFI noise is caused by electrical equipment that isn't properly shielded. This can be everything from your power supply to your computer's CPU fan. When these devices aren't sufficiently shielded, they can cause electrical interference that manifests as a high-pitched noise. And in some cases, this noise can be so loud that it's actually painful to hear!

RFI noise can sound like a lot of things, depending on the person hearing it. Some people compare it to a high-pitched buzzing, while others say it sounds more like white noise. In any case, it's generally considered to be a very annoying sound that can make it difficult to concentrate or even enjoy your favorite activities.

Now - what is causing that brutal noise in the first place?

Why Is My Power Supply Creating RFI Noise?

There are two main reasons why your power supply might be causing RFI noise. The first is that the power supply itself is cheaply made and doesn't have proper shielding. This means that the electrical components inside the power supply are more likely to cause interference.

The second reason is that the power cord itself is acting as an antenna and picking up interference from other electronic devices. This is more common in homes with a lot of electronic devices, as the cords can act as a giant antenna and amplify the interference.

Fortunately, there are some easy solutions to both of these problems. Let's address the main topic at hand today - how to stop RFI from AC to DC power supply.

Is RFI Noise Really A Problem I Need To Fix?

You might be wondering - do I really need to spend the time, energy, and money to fix the RFI noise? Or can I just live with this bothersome sound in the meantime?

The answer is - it depends. RFI noise can be more than just a nuisance. In some cases, it can actually cause pain! This is because the high-pitched sound can cause headaches, fatigue, and even ear damage. If you're struggling with any of these symptoms, we recommend taking action to reduce the RFI noise in your environment.

But even if you're not experiencing any pain from the RFI noise, it's still worth considering how this electromagnetic pollution might be affecting your health in other ways. Studies have shown that EMF pollution can contribute to anxiety, stress, and insomnia. So if you're looking for ways to improve your sleep or reduce stress levels, getting rid of RFI noise might be a good place to start.

How To Fix Stop RFI From AC To DC Power Supply - Fixing Your Existing Unit 

There are all sorts of crazy claims we see online promising to fix your problem with RFI noise from the power supply. However, there are really only two options you can choose from - fixing your existing unit or replacing it altogether with a superior alternative.

While we recommend you fix the root cause of the issue by replacing your cheap, low-quality power supply, we know that isn't always an option. So, let's start by explaining how to stop RFI from AC to DC power supply by fixing your existing unit.

Fixing Your Existing Unit (Not Ideal)

If your power supply is causing RFI noise, it's likely because it's not properly shielded. While the #1 approach to fixing this issue is replacing the power supply altogether, that isn't always possible. Maybe you are on a budget - or maybe you had something custom built and need an immediate fix while you await a new build. In this case, you can try shielding the unit yourself. You can try wrapping the power cord around ferrite beads, which are small objects that help to reduce interference.

You can also try using an AC line filter, which is a device that helps to reduce the amount of interference that's coming into your home from outside sources. These filters are relatively inexpensive and can be found at most hardware stores.

Installing an AC line filter is a pretty simple process. First, you'll need to find the breaker box and turn off the power to your home. Once the power is off, you'll need to remove the cover of the breaker box so you can access the wires. Locate the wire that's going into your power supply and disconnect it from the breaker box. Then, connect one end of the AC line filter to this wire and reconnect it to the breaker box. The other end of the AC line filter will go into your power supply. Once everything is connected, you can turn the power back on and see if the interference has been reduced.

The problem with attempting to fix your existing unit is that you could end up making matters worse - especially if you aren't an expert on electronics. Even if you fix the RFI noise, you could potentially damage the unit to the point it no longer works efficiently. That's why we recommend skipping this step altogether and fixing the root cause of the noise - by replacing the unit altogether.

Replacing Your Power Supply (Best Approach)

The best way to stop RFI from AC to DC power supply is to replace your power supply with a high-quality unit that has proper shielding. There are a few things you'll want to keep in mind when shopping for a new power supply. First, make sure that the unit has active PFC, or power factor correction. This feature helps to reduce electrical waste and can improve the efficiency of your power supply. Second, look for a power supply with a 120mm or larger fan. Larger fans run more slowly and produce less noise. Finally, make sure that the power supply is rated for at least 80% efficiency.
