iFi – iPower

Rated 5.00 out of 5 based on 2 customer ratings
(3 customer reviews)

A sensible upgrade for everyone: an ultra low noise switching power supply, at a great price. This PSU can be hooked to any 5V audio device, and since Power Supply is so crucial in the audio domain, what you’ll get is an audible improvement.

iPower: a brand new audiophile-standard 5V DC-power supply.

A little gem: a ultra low noise power supply, for less than 50 euros. As all of you know, power supply is one of the most critical components of Audio Gears. So, for those looking for an affordable yet very effective upgrade: look no further.

This clever PSU, albeit being a switching and not a linear one, will feed your equipment with sweet, unrippled DC. And it comes with a set of universal plugs and connectors.


  • Comes with universal plug socket adapters and connectors
  • A great Switching PSU = guaranteed audible improvements
  • Can be used to power the Raspberry PI (or any 5V board) via GPIOs (PI) or standard 5v connectors (other boards)
  • With a little tinkering you can power any audio device in your system

The central characteristic of iFi is in pursuit of the zenith in audio performance: it leaves no stone unturned. Well, the all new iPOWER is an exemplary example of this. Despite the fact that the iFi Ultra-Low Noise AC/DC adapter was exceptionally quiet and elevated the iUSB and iPhono to punch way beyond their respective categories, the all new iPower is even quieter, up to 10x quieter in fact.


Which products is it aimed at?
Virtually any DC powered device.
Just check the correct voltage (5V).
Check the correct polarity setup (see ‘Polarity Inverter’ below)
Ensure the current output is sufficient, then plug in and enjoy.


Advanced DC power design – the best has just been bettered. Three years ago, iFi’s Ultra-Low Noise AC/DC power adapter set the way and underpinned the whole iFi range from the iUSB to the iPhono leading to their loyal following. Well, not to rest on its laurels, iFi now has a completely new ‘ground-up’ DC powered supply.


Active Noise Cancellation+® drawn from military radar technology

Drawing from the military field (specifically the Thales Spectra radar cancellation system deployed in the French Dassault Rafale jet fighter), iFi adapted this technology to exclusively introduce the Active Noise Cancellation+ ® (ANC+®) audio power system. It is so good ANC technology is now a cornerstone of the ever-improving iFi USB audio technology range. An air defence radar is transmitting at a certain frequency; the signal is bouncing off the aircraft; a receiver on board the aircraft picks up the signal and a computer analyses its base frequency/modulations and an identical, out-of-phase signal is generated by an onboard system to cancel out the enemy radar signal. By generating a signal identical to the noise signal but in the exact opposite phase, it actively cancels all the incoming noise. ANC+® is the perfect ‘antidote’ for power supply noise, the bane of USB audio. With ANC+® the power line is filtered for audio band and RF noise. The measured noise floor of 1uV (0.000001V) is at the measurement limit of what even the most sophisticated Audio Precision equipment is capable of.


What audio noise floor?

Measured on the Audio Precision 2, the iPower has an astonishingly low audio band noise floor of just 1uV! To put this into context, iFi’s very own Ultra-Low Noise AC/DC adapter was in a class of its own at 10uV. Compared to a typical audiophile Linear Power Supply which measured at 20uV, it is demonstrably clear AMR/iFi power supply technology is unparalleled.


12-Element Output Array/6-Element Input Array

Shaping the face of technology, AMR/iFi not only pushes the boundaries of audio design, but power design too. After all, electricity is the ‘fuel’ behind the audio signal.There are two separate, but similar ‘Array Technologies’ in the iPOWER:

12-Element Output Array – is for addressing noise on the output (at the DC barrel) end. 6-Element Input Array – is for dealing with noise at the input (at the 2-pin mains) end.

What this means is that any noise is contained and neutralised with the iPOWER to halt it from contaminating the local mains or audio system. iFi is one of a handful of companies that manufacture ‘battery quiet’ DC power supplies. Just like hybrid technology in cars, both have come a long way in a short space of time and are gaining wider acceptance.


Polarity Inverter Adapter for ‘centre negative’ audio products At iFi, we like to think comprehensively and while the majority of home and pro audio products have a ‘centre positive’ DC power connector type, if your product such as a guitar pedal or a Sony Discman has a ‘centre negative’ instead of ‘centre positive’ pin, it is important to use the iFi power inverter. If you are unsure of the DC polarity of your product, please check with your vendor. For equipment using a DC power connection, it is common practice to include protection circuitry against over-voltage/reverse polarity, but not every manufacturer will have applied this. Always check first as AMR/iFi is not responsible for incorrect use or damage arising from use of the iPower.


Can be used globally; world-wide suitability

AMR/iFi understands and appreciates that today, being portable and user-friendly is paramount. So the iPower is light, convenient and above all, easy to travel with and work in any country in the world. The 5V version comes for all manners of DC powered devices and a set of interchangeable pins to span the globe: for USA/UK/EU/AUS electrical outlets. Performance and portability personified. In summary, all the technology behind the iPower would count for little if it was not audible. Well, it is both. With the all-new iPower, the noise floor is virtually inaudible and the all-important level of refinement (whether listening to an analogue or digital source) has been amplified several notches. Best of all, all existing iFi-powered devices all benefit, and in the different DC-power versions, the iPower now compliments non-iFi DC-powered products too. So all can enjoy the “sound of iFi.”

    Do you have the schematic of this PSU?
    How it works?

    I tried this power supply, 2 different units, with Allo Boss Dac (and hifi berry +) ans RPi 3, and I get an incredible noise.
    never understand how and why, but it was so.
    Perhaps a faulty series ?

    I came back to a 5€ very basic model, and it works nice.

    Perhaps I’ll try a big linear power supply, later.

    Wanted something better than my cheap samsung mobile adapter, I read some good reviews of the iPower and gave it a go. Well, that makes a big difference (PI3 + Mamboberry ). Since it comes with a plethora of different connectors I can connect it directly to the PI or the Mamboberry, altough the second configuration is clearly the best sounding one.

    No, I don’t think they released the schematics. It is a Ultra low noise switching PSU, personally I’m really satisfied with it!
