AudioQuest Thunder High Current Power Cable - 2.0 Meter - 15 amp

Thunder High Current Is Built for Amplifiers and Conditioners

A power cable carries the last few feet of AC from the wall into a component. It can't add power a component doesn't draw, but a poorly shielded one lets noise ride in on that current.

AudioQuest's Thunder High (Variable) Current cable is optimized for AC power conditioners, regenerators, power amplifiers and any component with a built-in amplifier, including AV receivers, powered speakers and powered subwoofers. It carries a full 20-amp continuous rating built for that variable load.

Perfect-Surface Copper and Perfect-Surface Copper+ Conductors

AudioQuest combines solid, high-purity Perfect-Surface Copper (PSC) with extreme-purity Perfect-Surface Copper+ (PSC+) to prevent strand interaction, which it calls a major source of ear-fatiguing transient intermodulation distortion. It says the astonishingly smooth, pure PSC eliminates harshness and increases clarity compared with OFHC, OCC, 8N and other premium coppers.

20-Amp ZERO-Tech and 72-Volt DBS

AudioQuest's ZERO-Tech design rates Thunder at 20 amps RMS at 125VAC, with headroom for current transient peaks well above that continuous rating. It says that suits power conditioners, regenerators, isolation transformers, amplifiers, powered subwoofers and receivers alike. A 72-volt Dielectric-Bias System and RF/ND-Tech's patented phase-cancelling array keep induced RF noise off the current path.

The Connectors, Explained

Thunder High Current is available with a C13, C15 or the higher-current C19 inlet plug to match your amplifier or conditioner's power inlet, and a standard NEMA 5-15 three-prong plug for the US wall outlet at the wall end.

Who Is This Power Cable Best For?

• You are feeding a power amplifier, AV receiver or power conditioner — AudioQuest built Thunder High Current specifically for that variable, high-current draw
• Your gear needs the full 20-amp headroom this line is rated for — the ZERO-Tech design is built to deliver that current uncompressed
• Your amplifier or conditioner takes a C19 or C15 inlet rather than C13 — Thunder High Current is offered in all three terminations
• Your rack sits in a noisy RF environment — the 72-volt Dielectric-Bias System and RF/ND-Tech's phase-cancelling array work together to keep that noise off the current path
• You are feeding a source component rather than an amplifier — AudioQuest NRG-Z3 is built for that lighter, steadier draw at a lower price

How Does It Connect to Your System?

Plug the C13, C15 or C19 end, whichever matches your amplifier or conditioner, into its IEC inlet, and the male end into a wall outlet or power conditioner outlet.

Then power up the system as usual. Other and longer lengths available. Call for prices.

Pairs Well With

A power cable is one link in the chain from the wall to your gear. It usually joins these categories.

• Power Conditioners — filter the whole circuit; the cable feeds the last few feet after it
• Integrated Amplifiers — the high-current load most power cables are built to feed
• Stereo Amplifiers — another high-current destination for the heavier gauges in this range
• Digital-to-Analog Converters — a low-current source component that still benefits from clean, quiet AC

Frequently Asked Questions

What does 20-amp ZERO-Tech mean in practice?

AudioQuest rates Thunder's current capacity at 20 amps RMS at 125VAC, which it says lets the cable withstand current transient peaks many times its continuous rating without constricting them, ideal for the variable draw of an amplifier.

Why does shielding matter on an AC cable?

AudioQuest builds its power cables to keep radio-frequency and electromagnetic noise from riding in on the AC line and reaching sensitive circuits. A ground wire without that shielding can act like an antenna, pulling in exactly the noise a power cable is supposed to keep out.

Do power cables wear out?

Every metal conductor oxidizes over time; it is unavoidable chemistry, not a defect. What varies is the rate. Denser, better-shielded conductors with quality plating oxidize far more slowly, so a well-made cable performs the same way for years instead of drifting.

Will this affect my system's ground safety?

No change to your safety ground. Every cable in this line keeps the full three-conductor path, hot, neutral and ground, exactly as building code requires. What differs from a stock cord is conductor quality and shielding, not the wiring topology.

Is there a step up?

AudioQuest Tornado High Current is the next rung, and the top High Current cable we carry. AudioQuest positions it a step up from Thunder in its flagship Storm Series.
