iFi audio iPower X

Ultra-Low Noise Power Supply | Active Noise Cancellation 2 | Cleaner Power for Superior Sound

Overview

The iFi audio iPower X is the next-generation ultra-low-noise power supply, engineered to deliver exceptionally clean and stable DC power for high-performance audio systems. Building on the success of the original iPower introduced in 2015, iPower X features a fully optimized internal architecture, improved noise suppression, increased output capability, and a refined new design.

Designed to outperform both standard switching adapters and even audiophile-grade linear power supplies, iPower X dramatically reduces electrical noise, allowing connected audio components to perform at their full potential.

Cleaner Power Than Ever Before

Extremely Low Noise Floor

Audio-band noise floor as low as 1μV
Up to 1,000× quieter than standard SMPS wall adapters
Quieter than traditional audiophile linear power supplies

Unclean power introduces noise, distortion, and dynamic compression. iPower X eliminates these limitations, unlocking improved clarity, dynamics, and spatial detail.

Active Noise Cancellation 2 (ANC II)

Unlike passive filtering used in conventional power supplies, iPower X employs Active Noise Cancellation II, a technology inspired by active noise-cancelling headphones.

Measures incoming EMI/RFI noise in real time
Injects an inverse phase signal to cancel noise before it reaches your device
Works across a much wider frequency range than passive filters

The result is dramatically reduced electrical noise and a purer power signal that allows your system to sound more open, detailed, and natural.

Advanced Internal Design

iPower X features a completely upgraded power architecture:

Oversized Power MOSFET for improved current handling
New low-leakage transformer
45W high-performance adaptive multi-mode controller
Frequency shifting for superior EMI performance
220% increase in power supply capacitance
106% increase in input filter capacitance
79% increase in output filter capacitance
High-density output inductors
Aluminum conductive polymer solid capacitors
Upgraded RF-optimized PCB design
Enhanced transient protection and oversized heatsinking

These improvements work together to suppress high-frequency noise, reduce ripple, and deliver stable power under dynamic load conditions.

More Power, Broader Compatibility

Delivers 150% more peak power than the previous iPower generation
Suitable for a wider range of audio devices including DACs, streamers, headphone amplifiers, and network components

Refined Design

The iPower X introduces a modernized chassis with a harmonious cream/beige finish. The sculpted top surface adds visual elegance, while a soft blue LED discreetly indicates power connection.
