Audiophile Linear Power Supply for Pure, Stable Power.Upgrade your hi-fi audio system with a low-noise linear power supply. Featuring a custom 80W toroidal transformer (100W peak), premium Nippon Chemi-Con capacitors, TI linear regulators, and a high-performance rectifier, it delivers ripple noise as low as 0.1mV for clean, stable power. Selectable 5V/12V/15V outputs make it ideal for DACs, streamers, headphone amplifiers, and other low-voltage audio devices.
Power Multiple Devices with One Linear Power Supply.Simplify your hi-fi audio setup with 2 DC outputs and 1 USB-A output, powering your DAC, streamer, CD player, headphone amplifier, and other low-voltage audio devices from a single linear power supply. Selectable 5V, 12V, and 15V outputs provide broad compatibility while reducing cable clutter and eliminating multiple power adapters for a cleaner, more organized desktop.
Independent Isolated Outputs for Cleaner Audio.Each output features independent rectification, filtering, and voltage regulation to deliver clean, stable power without interference. Fully isolated grounds eliminate ground loop noise, making this linear power supply ideal for powering multiple DACs, streamers, headphone amplifiers, and other hi-fi audio devices simultaneously.
Quiet, Safe, and Built to Last.A custom 30dB silent cooling fan keeps this linear power supply running cool and stable. Built-in overheat, overvoltage, and overcurrent protection safeguard both the power supply and your DAC, streamer, headphone amplifier, and other hi-fi audio equipment. Front-panel voltage indicators make operation simple, day or night.
Seamless Fosi Audio Integration: Designed with the Fosi family aesthetic, PSU20 pairs perfectly with DACs, power amplifiers, and CD players like S3, ZD3, and Merak CD. The optimized 12V output and matched design create a clean, space-saving hi-fi desktop audio system.
