iFi audio SilentPower Nova 1,8 m Hi-Fi Power Supply

Clean Mains Power for Sensitive Hi-Fi Systems

The iFi audio SilentPower Nova is a true balanced IEC power cable built to feed high-end audio and AV components with the cleanest possible mains electricity. Five heavy-gauge continuous-cast OFHC (Oxygen-Free High Thermal Conductivity) copper conductors are arranged in a geometrically balanced configuration, with two pairs of live and neutral conductors flanking a central earth conductor. This layout, branded Ground Zero, cancels the magnetic fields of the live and neutral lines so no residual field is induced on the ground conductor. The SilentPower Nova is the right choice for hi-fi owners who want to reduce mains-borne noise reaching their amplifiers, DACs, and source components.

What Sets the Nova Apart

Where most mains cables twist their conductors together, the Nova keeps the ground conductor in a straight shotgun configuration at the centre of the cable, eliminating the unwanted induced voltage that ordinary designs pass on to the ground line. Concurrent shielding on each individual power line holds impedance constant and protects the signal path from electromagnetic and radio-frequency interference. The cable is finished with a tough yet flexible polymer outer sheath and iFi's bespoke audiophile-grade connectors, complete with 24ct gold-plated oxygen-free copper conductors.

Who Is It For

The SilentPower Nova suits hi-fi enthusiasts and home-cinema owners who already have a refined system and want to address the often-overlooked variable of mains quality. It is a sensible upgrade for owners of integrated amplifiers, DACs, network streamers, and other source components where a quieter power feed can translate into a more stable soundstage and tighter low-frequency response. The 90V to 265V operating range means it can be used with virtually any mains standard worldwide, and the flexible outer sheath makes routing the cable behind racks and between components straightforward.
