A power cable fit for your finest equipment

A growing number of high-performance audio and video components come with a detachable AC power cord. That makes it easy for you to upgrade to a higher-quality cable. Simply replacing your component's stock power cord with AudioQuest's NRG-3 AC power cable can noticeably improve your system's picture and sound quality. The idea of a high-quality power cord is new to most people, but AudioQuest has been refining their NRG low-distortion cables for years.

Why power cords make a difference

The AC power that feeds your gear is really the foundation of your system's audio and video performance. Even if you've plugged your components into a power conditioner to clean up the current coming out of your wall, a flimsy stock power cord can act as an antenna for airborne interference that subtly degrades high-resolution audio and video signals.

Advanced materials and construction for lower distortion

The NRG-3's advanced "geometry" features an inner circle of three 19-gauge conductors surrounded by an outer circle of ten 21-gauge conductors in a self-shielding counter-spiral configuration. All conductors are solid, made of AudioQuest's best Perfect-Surface Copper. Solid conductors eliminate interaction between wire strands, which is a major source of distortion in an AC power cable.

Every NRG-3 cable features two barrel-shaped RF stoppers that filter RFI (radio frequency interference) in both directions. They keep outside interference from entering your equipment, while also preventing noise generated by your digital gear from affecting other components in your system.

Make sure it fits your component

The NRG-3 works with most components that come with a detachable two- or three-pole "IEC" power cord (see illustration above). That includes many high-performance A/V receivers, audio separates, DVD players and Blu-ray players, as well as many HDTVs and most video projectors.

Product Research


Overview: The Audioquest NRG-3 Power Cord (IEC-3 Pole) uses solid Perfect-Surface Copper (PSC) conductors in a Self Shielding Counter-Spiral Hyperlitz geometry. Solid conductors prevent strand interaction, which is the greatest single source of distortion in an audio cable or an AC power cable. The nearly perfect surface finish and interior grain structure of PSC copper dramatically reduce distortion compared to OFHC or other metals. The Counter-Spiral geometry minimizes conductor interaction while maintaining a fixed low-inductance relationship between conductors.

Construction: The Audioquest NRG-3 Power Cord features thirteen solid perfect-surface copper (PSC) conductors (Inner Circle: 3 x 19 AWG solid PSC; Outer Circle: 10 x 21 AWG solid PSC) inside a UL CL-3 rated black PVC jacket surrounded by a black, red, and blue flexible nylon braid.

RF Stopper: The Audioquest NRG-3 Power Cord's two RF Stoppers filter radio frequency interference in both directions. They prevent outside interference from entering the equipment, and they prevent equipment generated interference (from all digital equipment and tuners) from reaching other equipment in the system.

Connectors: The Audioquest NRG-3 Power Cord features a 3-pole IEC connector on one end to plug into your audio/video electronic component and a 3-prong North American AC connector on other end to plug into your AC wall outlet.

Available Lengths: The Audioquest NRG-3 Power Cord is available in a 3' and 6' length.
