Ultra-low noise floor (~1µV) for cleaner DC power
Designed to deliver exceptionally quiet power that supports lower noise, better stability, and improved device performance in sensitive systems.
Four output options: 5V, 9V, 12V, or 15V
Choose the correct voltage/current variant for your device to ensure proper operation while maximizing noise suppression benefits.
Multi-tip compatibility plus reverse polarity (white plug)
Includes common DC barrel sizes and a reverse-polarity option to broaden compatibility—especially helpful for certain professional audio devices requiring center-negative power.
Improved components and thicker-gauge wiring
Upgraded build focus supports stronger input/output noise suppression and reliable power delivery across demanding setups.
Versatile for audio, AV installs, streaming/network, and lighting
A strong fit for DACs, interfaces, AV processors, switchers, network streamers/switches, and regulated-output applications where stability helps reduce flicker or interference.

iFi SilentPower iPower2 - Low Noise DC Power Supply
SilentPower iPower2 is an ultra-low noise DC power supply built to replace the “noisy brick” that can add hiss, grain, flicker, and digital hash to sensitive electronics. Using Active Noise Cancellation II, it actively cancels incoming EMI/RFI by generating an inverse noise signal—delivering cleaner, steadier power to the device at both input and output stages. With upgraded internal components and thicker-gauge wiring, iPower2 is designed to improve power stability and reduce noise across home audio, professional AV, streaming/network gear, and custom installs. Choose the correct voltage/current option (5V, 9V, 12V, or 15V) and enjoy a simple plug-in upgrade that helps equipment perform at its best.
What It's Good At:
Reducing hiss, hum, grain, and digital noise caused by standard switching power supplies
Actively cancelling incoming EMI/RFI with Active Noise Cancellation II for cleaner power delivery
Improving performance of streamers, DACs, headphone amps, phono stages, and audio interfaces
Stabilizing power for AV processors, switchers, extenders, scalers, and HDMI splitters in install racks
Minimizing LED flicker and interference in lighting and studio/AV environments with regulated output
Boosting compatibility with multiple DC barrel sizes, including a reverse-polarity adapter for center-negative devices

iFi Silent Power iPower2 Q&A:
What does the iPower2 do, and why would it improve my system?
iPower2 replaces a standard DC adapter with an ultra-low noise supply that actively cancels EMI/RFI and reduces electrical noise that can lead to hiss, grain, interference, or instability.
How do I choose the correct iPower2 version for my device (5V/9V/12V/15V)?
Match the iPower2 output voltage to your device’s required voltage and ensure the current rating meets or exceeds what your device needs (choose the exact voltage; current can be higher than required).
Will it work with professional audio gear that uses center-negative polarity?
Yes. A reverse polarity adapter (white plug) is included to support compatible center-negative devices.
Which DC plug sizes are supported?
iPower2 includes multiple DC tips: 3.5×1.35mm, 4.0×1.7mm, 4.8×1.7mm, 5.5×2.1mm, plus a 5.5×2.5mm reverse polarity plug (white).
How quiet is the iPower2 compared to typical power supplies?
It’s engineered for ultra-low noise performance with a ~1µV noise floor and is rated up to 20× quieter than normal SMPS designs.
How do I use the iPower2?
Plug the iPower2 into AC power, fit the appropriate DC tip if needed, and connect it to your device’s DC power input to provide ultra-low noise, stable, efficient power.
What’s included in the box?
The box includes 1× iPower2 and 1× user manual (with the included DC tip set and reverse-polarity option as part of the output plug system).
Is there anything special about the 5V model?
Yes. The 5V iPower2 includes USB-C > DC and USB-micro > DC pigtails for additional connection flexibility.
