iFi Audio SilentPower iPower X Power Supply

iFi SilentPower iPowerX Power Supply

The SilentPower iPowerX is an ultra-low-noise AC/DC power supply built to upgrade the performance of demanding audio and digital gear that’s sensitive to electrical contamination. Its active noise cancellation tackles low- and mid-frequency noise, while additional filtering helps suppress higher-frequency interference—resulting in cleaner power, a darker background, and more natural detail from devices like DACs, headphone amps, streamers, routers, and more. With advanced output filtering and premium internal components, iPowerX helps reduce leakage noise versus typical switch-mode power supplies, improving clarity, separation, and overall system focus. Finished in a sleek cream/beige chassis with a backlit logo, it’s a simple, high-impact upgrade for anyone chasing quieter power and better fidelity.

What It's Good At:

• Lowering the noise floor for cleaner, more “silent” backgrounds and improved micro-detail
• Improving clarity and separation by reducing power-related interference and hash
• Feeding sensitive audio gear (DACs/amps/phono stages) with stable, ultra-low-noise DC power
• Upgrading digital devices (routers/streamers) to help reduce electrical noise in the signal chain
• Broad device compatibility thanks to multiple output voltage options and included plug sizes
• Premium filtering approach that targets both low/mid noise and higher-frequency interference

iFi iPowerX Q&A:

Why doesn’t the iPowerX include all country plug types in the box?

To reduce unnecessary waste, the iPowerX does not include every country plug by default since most users only need one plug type. Interchangeable UK/US/EU/AU pins are available separately.

What DC barrel size does the iPowerX use?

The standard DC barrel size is 5.5 × 2.1mm.

Which devices is the iPowerX best suited for?

It’s designed for noise-sensitive audio and digital equipment such as DACs, headphone amps, streamers, and routers that benefit from cleaner, lower-noise DC power.

How do I connect the iPowerX to my gear?

Connect iPowerX to your device’s DC power input using the correct output plug/adapter so it can deliver ultra-low-noise, stable power for improved performance.

What output voltages are available?

iPowerX is offered in 5V, 9V, 12V, and 15V versions, each matched with a specific maximum current rating.

Does iPowerX help with audible hiss or background noise?

By reducing electrical noise from the power supply, iPowerX can help lower perceived background noise and improve clarity—especially with revealing audio systems.

Are the interchangeable mains pins included?

No—UK/US/EU/AU interchangeable pins are sold separately.

What comes in the box?

You receive 1× iPower X and 1× User Manual.
