Features & Specs
True geometrically balanced conductor layout
Helps cancel magnetic fields created by live and neutral conductors, aiming to reduce interference that can blur detail and dynamics.
Ground Zero core design approach
Forms a central core engineered to be free from magnetic-field influence, supporting cleaner power delivery to sensitive audio circuits.
Concurrent shielding for individual power lines
Targets EMI/RFI at the conductor level to help keep noise from entering (or leaving) the cable path and impacting nearby equipment.
Heavy OFHC continuous-cast copper conductors
Focuses on high conductivity and consistency to support strong current delivery and stable component performance.
Gold-plated pure copper terminations
Designed to maintain solid contact integrity and efficient transmission over time, helping reduce connection-related losses.
Ground-line design intended to reduce ground loop noise
Uses a dedicated, non-twisting ground approach to help minimize hum and other ground-related artifacts in compatible setups.

iFi SilentPower Quasar Power Cable
SilentPower Quasar is an audiophile-grade mains power cable designed to reveal what cleaner power can do for hi-fi and home theater systems without jumping straight to ultra-costly upgrades. Built around a true geometrically balanced conductor layout, Quasar helps cancel magnetic fields generated by live and neutral conductors, lowering interference that can mask detail and dynamics.
Quasar also incorporates iFi’s Ground Zero design approach to form a central core engineered to be free from magnetic-field influence, helping your components receive steadier, quieter power. Its construction focuses on robust materials—heavy OFHC continuous-cast copper, durable polymer structures, and gold-plated pure copper connections—so you get reliable everyday use with premium signal transfer.
For systems that need a cable friendly to a wide range of electronics (including demanding gear), Quasar’s design aims to maintain consistent performance while reducing EMI/RFI intrusion for cleaner electricity to your audio or AV chain.
What It's Good At:
Lowering perceived noise by helping reduce EMI/RFI reaching sensitive audio and AV components
Improving clarity, separation, and low-level detail by delivering cleaner mains power
Supporting a wide range of systems with a true balanced geometry that helps cancel magnetic fields
Providing durable long-term use with impact-resistant polymer construction and moisture-unaffected materials
Maximizing connection integrity with gold-plated pure copper terminations
Helping minimize ground-related issues via a dedicated ground-line design intended to reduce ground loop noise

iFi Quasar Q&A:
How do you connect the Quasar power cable?
Connect the IEC end to your audio or video component, then plug the other end into a wall outlet or power conditioner. Ensure both ends are fully seated before powering on your system.
What does “true balanced” mean in a power cable like Quasar?
Quasar uses a geometrically balanced live and neutral layout intended to cancel magnetic fields created by current flow, helping reduce interference that can affect system performance.
Will Quasar work with my system’s voltage?
Yes—Quasar is specified for 90V to 265V, covering common household mains standards across many regions.
Is Quasar suitable for high-power audio gear?
Quasar is rated up to 25A max (cable rating) and is designed to support demanding audio/AV setups within its socket rating limits.
How does Quasar help with EMI/RFI noise?
Its design uses shielding at the power-line level and a balanced geometry to help reduce susceptibility to external and internal EMI/RFI, supporting cleaner power delivery to your components.
Does Quasar help with ground loop noise?
It includes a dedicated ground-line approach intended to reduce ground loop noise, which can contribute to hum or unwanted background artifacts in some systems.
What length is the Quasar cable?
Quasar is 1.8 meters (70.8 inches), a practical length for most racks and power-conditioning setups.
What’s included, and what warranty coverage is provided?
The box includes the Quasar cable and a user manual, backed by a 12-month warranty.
