When is a plug no ordinary plug? When it’s an iFi iPower.
Use an iPower to replace your regular power supply for clean, noise pollution free power.
Power hungry
Got underlying noise in your system you can’t explain?
It could be as simple as your power supply.
Upgrade to the iFi iPower to feed your system’s circuits with clean, audiophile grade power and address issues at both the output and input stages.
iPower for LED lights
Photography? No way. iPower can also solve my flickering LED light problem?
Yes, a constant current and voltage power supply like iPowerX will ensure that the current supplied to your LED system will remain stable, no matter the fluctuations of the AC power in your wall socket.
It can be used all over the world as it comes with pins for the USA, United Kingdom, Europe and Australasia.
Quiet! Active Noise Cancellation+® (ANC+) at work!
Exceptionally quiet power. The measured noise floor is 100x quieter than the common noise filter.

Reviews
Excellent low noise power supply.
Excellent product. Perfect for high quality audio equipment. No hum at all as expected. A little expensive but worth it.

Worthy upgrade, decent!
This little thing definitely does make a difference on the sound quality, the design is better than the previous one. Not the cheapest one but it is what it is, if you want great stuff, most of the time you will need to spend a bit more. It does exactly what it says so yes, it is a worthy upgrade. Delivery was super-fast and as someone said on a review ‘IFI sells premium olive oil and not snake oil.’ Couldn’t agree more!

Powers the raspberry pi4b
Pleased with this. Powers the Pi4b without the dreaded lightning bolt.

Brilliant for preamp and turntable system
Brilliant, I got this for my 5 volt IFI Zen Phono preamp for use in my vinyl only system, their was a slight hum only when I picked up the headshell part of my Thorens TD160, this is completely gone now, thoroughly recommend it. It works as promised!

Exactly as described – a very clean DC output
My audiolab M-DAC+ didn’t like the optical output from my new LG OLED55G1 (drops out for less than a second intermittently) so bought a really cheap optical/coax converter with a 5V USB PSU that let through lots of HF mush. This PSU cleaned up the signal.
Customers & many manufacturers fail to recognise the importance of the PSU in audio products! This is a switch mode PSU so will work anywhere in the world that has a reliable mains supply. The other aspect worth mentioning is the ability to connect to virtually any device including ones with Micro USB & USB C sockets of either polarity. Cost 4x more than the cheapo DAC but now get decent sound from my TV.

EMI (Electromagnetic Interference)
EMI is a type of interference caused by errant and unwanted electromagnetic waves that are received and amplified by an audio system. They cause some of the annoying ‘audio gremlins’ we often talk about.
RFI (Radio-frequency interference)
Radio-frequency interference (RFI) is very similar to electromagnetic interference (EMI) but is found in the radio frequency spectrum. It is another source of irritating, unwanted noise often talked about as an ‘audio gremlin’.
Top tip: just don’t add water.
Switch Mode Power Supplies (SMPS)
A switched-mode power supply is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently. It transfers power from a DC or AC source to DC loads, such as a personal computer, while converting voltage and current characteristics.
Switch-mode power supplies are widely used because of the advantages they offer in terms of size, weight, cost, efficiency and overall performance. They are in themselves noisy and were not designed with audio in mind.
Active Noise Cancellation
Active Noise Cancellation (ANC) reduces unwanted sound by the addition of a second sound wave specifically designed to cancel out the first. This basically results in no sound at all as it reaches unwanted sound even at the lowest frequencies.
Passive noise cancellation is done by means of insulating filters and works best on the middle to high frequencies. It does not work on the lower frequencies meaning that some sound can still be heard.
