Features & Specs
Active Noise Cancellation II (ANC II) for wide-band noise reduction
ANC II actively targets noise across the frequency range instead of relying only on passive filtering, helping reduce the perceived noise floor and revealing finer musical detail.
Concurrent shielding to resist EMI/RFI and maintain stable impedance
Individual power lines are shielded to reduce interference pickup, supporting cleaner electricity delivery to sensitive audio circuits and digital components.
Geometrically balanced design across live, neutral, and earth
By balancing the conductors, SupaNova improves noise immunity and helps reduce unwanted induction effects, especially into the earth wire.
Ground Zero technology for a low-interference central core
The internal structure is engineered to create a core that is free of magnetic fields, supporting a cleaner electrical environment for connected equipment.
High surge protection capability for added peace of mind
With a surge protection rating up to 10,000A, SupaNova helps guard against damaging spikes that can threaten high-end components.
1.8m (70.8") length for practical system integration
The cable length is ideal for most rack and hi-fi placements, giving flexibility without excess slack while keeping the active module positioned conveniently.

iFi SilentPower SupaNova Power Cable
The SilentPower SupaNova is a high-performance active IEC power cable designed to reduce mains-borne noise and help your audio or AV system deliver cleaner, more revealing sound. Unlike standard power leads, SupaNova combines advanced concurrent shielding with Active Noise Cancellation II (ANC II) to actively suppress noise across the frequency range on live, neutral, and earth—helping lower the noise floor for improved clarity, separation, and definition. Built with a geometrically balanced design and SilentPower’s Ground Zero technology (a central core engineered to be free of magnetic fields), SupaNova improves immunity to EMI/RFI and maintains stable performance under real-world conditions. It also includes surge protection, making it a practical upgrade for high-value audio gear where power purity and protection matter. Simply connect SupaNova between your power source and your component to introduce active noise reduction directly at the device—often reducing reliance on additional conditioning hardware.
What It's Good At:
Lowering the noise floor for clearer detail, cleaner treble, and tighter bass definition
Improving instrument separation and soundstage for more space and dimensionality
Actively cancelling mains noise (ANC II) across live, neutral, and earth—not just passively filtering
Rejecting EMI/RFI with concurrent shielding to keep power delivery cleaner and more consistent
Adding surge protection to help safeguard audio/AV components
Delivering “do-it-all” clean power to individual components without needing a separate conditioner in many setups

iFi SupaNova Q&A:
What is the SupaNova power cable designed to do?
SupaNova is a fully balanced, low-loss power cable that combines Active Noise Cancellation (ANC II) with surge protection to reduce mains noise and improve system performance.
What is the maximum current rating for SupaNova?
It is rated up to 15A at 125V and up to 10A at 250V.
Where are the polarity and earth-status indicators located?
The barrel-shaped enclosure in the center of the cable houses the ANC circuitry and provides polarity and earth indication LEDs at one end.
Why does a “balanced” cable design matter for audio systems?
A balanced configuration improves immunity to noise by shielding the active conductors more effectively and reducing induction into the earth wire.
How do I use the SupaNova cable?
Connect it between your power source (wall outlet or suitable power extension block) and your audio/AV device’s IEC inlet, then power on your system as normal.
Does the cable still reduce noise if the LEDs show a warning condition?
Yes—regardless of LED color, the cable continues actively cancelling noise; however, you should correct any polarity/earth issues indicated.
What does “Active Noise Cancellation II” do in a power cable?
ANC II actively suppresses electrical noise by generating an inverse noise signal to cancel it, helping reduce interference beyond what passive filtering alone can achieve.
Does SupaNova replace a power conditioner?
In many systems, it can reduce the need for additional conditioning by delivering active noise reduction directly to the connected component, though results depend on your setup and power environment.
