iFi iPower X Ultra Low Noise AC/DC Power Supply

The Wall-Wart Is the Weak Link in Your System

Streamers, DACs, phono stages, and turntables almost always ship with a generic switch-mode wall-wart — the cheapest component in the box, feeding the most sensitive circuits you own. Those supplies are electrically noisy by design, and the noise doesn't stay put. It rides into the component's ground plane and analog stages, where it shows up as a grayer background, less air around instruments, and imaging that never quite locks.

Replacing it costs you nothing in setup time and works on gear you already own — which makes it one of the most efficient upgrades in the hobby.

Active Noise Cancellation II — Noise Killed at the Source

Instead of filtering noise after the fact, the iPower X generates a signal identical to the incoming EMI and RFI but opposite in phase, cancelling it out — the same principle behind noise-cancelling headphones. Passive insulating filters handle the higher-frequency interference on top of that.

The result is an audio-band noise floor of roughly 1 microvolt — a figure iFi puts at 100 times quieter than a standard stock wall-wart. Against the original iPower, the X adds 50% more input capacitance and 150% more output capacitance for greater peak power delivery, along with an oversized power MOSFET and a low-leakage transformer. The cream chassis carries a cyan backlit logo, so you can see at a glance that it's running.

Four Voltages — Choose the One Your Component Requires

The iPower X is a fixed-voltage supply available in four versions:

• 5V — up to 3.0A. Streamers, USB DACs, and small digital components.
• 9V — up to 2.5A. Phono stages, headphone amps, and effects pedals.
• 12V — up to 2.0A. Network players, DACs, routers, and many Pro-Ject turntables.
• 15V — up to 1.5A. Desktop DACs and components specified for 15V.

There's no switch or adjustment — each version outputs one voltage only. Check the label on your component or its original supply, confirm the voltage and that the current draw falls within the rating above, and order the matching version.

Fits More Gear Out of the Box

Where most aftermarket supplies leave you hunting for an adapter, the iPower X ships with a set of DC barrel adapters covering the common sizes — 3.5 × 1.35mm, 4.0 × 1.7mm, 4.8 × 1.7mm, 5.5 × 2.1mm, and 5.5 × 2.5mm. A white center-negative adapter is included for components wired in reverse polarity, which makes this a practical choice for guitar and effects pedals as well as hi-fi.

The two-meter cable gives you room to reach a rack shelf or the back of a desk without an extension.

Before You Order

Voltage must match exactly. Connecting a 15V supply to a 9V component can damage it. If your component needs a voltage other than 5V, 9V, 12V, or 15V, this is not the right product.

Confirm polarity. Most home and pro audio gear uses a center-positive DC connector, but some components are center-negative. The included white adapter covers that case — but you need to know which your component requires before connecting. Check the user guide, or call us and we'll look it up with you.

Frequently Asked Questions

Which version do I need?
Look at the label on your component's DC input or on its original power supply — it will list a voltage and a current rating. Match the voltage exactly, make sure your component's draw is at or below the iPower X rating for that voltage, and note the polarity symbol. If anything is unclear, call us before ordering.

Will I actually hear a difference?
It depends on how noisy your existing supply is and how revealing your system is. On sensitive digital components fed by a cheap generic wall-wart, the improvement is usually clear: quieter background, better separation, more solidity to the bass. On gear with a well-designed internal supply, expect something subtler.

How does this compare to the iPower Elite?
The iPower X is the right choice for most components — same 1 microvolt noise floor, broad adapter set, and a compact footprint. Step up to the Elite if your component draws more current than the X can supply for its voltage, or if you want the larger aluminum chassis and higher output for a bigger amplifier. Both use Active Noise Cancellation II.
