iFi’s SupaNova Active Power Cable Eradicates Noise and Brings Clarity to Your Favorite Music

  • Features tough but flexible polymer outer sheath, bespoke connectors, and 24k gold-plated oxygen-free conductors
  • 5 heavy-gauge OFHC conductors geometrically balanced along with air-dielectric delineators for isolation
  • Offers constant impedance and superior rejection of EMI/RFI, maintaining purity of mains electricity
  • Wireless Purification System significantly reduces power-line noise without side-effects
  • Terminated with US NEMA 5-15p to C15 connectors

The Sound of SilentPower

iFi’s new SilentPower range tackles mains-related noise to improve audio/AV system performance. Ifi has made a number of ‘clean power’ products in their nine-year history, but never a specialist IEC power cable for home audio components until now!

The SupaNova is a specialized active power cable with high-end construction that belies its affordable price point. It delivers a serious upgrade over standard mains leads that imbues sound with greater clarity, space and definition.

The Cable

The SupaNova incorporates five conductors, each made from heavy-gauge, continuous-cast OFHC (Oxygen-Free High Thermal Conductivity) copper, arranged in a geometrically balanced configuration – highly unusual at such a price point.

Two pairs of live and neutral conductors are arranged either side of the earth conductor, which is positioned at the centre of the cable. A further pair of air-dielectric delineators – essentially polymer matrix tubes filled with air – are arranged either side of the earth conductor, keeping the two pairs of live and neutral conductors apart whilst improving the cable’s overall dielectric performance and constructive solidity.

The cable is finished with a tough yet flexible polymer outer sheath and iFi’s bespoke audiophile-grade connectors, complete with 24k gold-plated oxygen-free copper conductors.

Ground Zero

The earth conductor is positioned at the centre of the cable, arranged in a shotgun configuration and not twisted around like other mains cables. The live and neutral conductors are arranged in a truly balanced configuration, hence their magnetic fields cancel each other out perfectly. As a result, there is no residual magnetic field being applied to the centre-ground conductor, and no unwanted induced voltage on the Ground conductor, an effect iFi refers to as 'Ground Zero.'

Intelligent Ground is a smart diagnostic tool. It will only actively provide an earth/ground connection if your system needs one. It will NOT create a ground loop if the system is already earthed/grounded. IFi's Ground Zero design ensures the grounding conductor within the cable is unaffected by residual magnetism and unwanted induced voltage.

Power Conditioning Activated!

The SupaNova takes the Nova and adds a cylindrical housing partway down its length. This contains our proprietary Active Noise Cancellation II technology.

ANC II actively eliminates far more noise across the frequency range than a passive product, even across the lower frequencies. We use inverse noise current to cancel out the noise in the mains signal. The way this works is comparable to the technology in noise-cancelling headphones.

A ‘Do-it-all’ Active Power Cable

By combining Nova’s sophisticated construction with Active Noise Cancellation II, the SupaNova has become a ‘do-it-all’ clean-power cable solution that delivers optimized power to individual audio/AV system components without the need for a separate mains conditioning device.

Sonic improvements delivered by the SupaNova power cable include greater clarity and definition, plus enhanced dynamic and spatial qualities, avoiding the apparent softening of leading edges, timing and dynamics that can occur with lesser mains filtering products.


IFi's Wireless Purification System (WPS) is a complex circuit that reduces power line noise without audible or measured side-effects. This is important because other solutions while attempting to curb noise, also hamper dynamics.

Over-voltage Surge Protection

The OSP is an auto-detection and cut-off circuit. Should it detect an excessive power surge or short in the mains electricity, it will automatically cut off. If this issue persists, it will not reboot and will protect your equipment from harm. It is effective to max. 30,000A @ 1,000V/10uS.


  • Noise Reduction: > 40dB (> 100x)
  • Surge Protection: max. 10,000A @ 775V / 8/20uS
  • Under Operating Voltage: Max operating rating 10A at 250Vac | 15A at 125Vac
  • Length: 70.8" (1.8m)
  • Weight: 1.49 lbs (675g)
  • IFi Warranty Card (1 Year)
