 Wyred4Sound PS-1 Modular Linear Power Supply 


The modular PS-1 linear power supply is powerful, affordable and modular.

Power up to four devices at once—it's the last DC power supply you'll ever need! 


For low-voltage DC powered devices, replacing the standard 'wall wart' switching mode power supply with a robust, quiet linear power supply can reap huge sonic benefits. For years, customers who purchased our award-winning "micro" products (Remedy, bLINK, µDAC, Recovery, etc.) have asked us if we also made a linear power supply to increase their performance, but our answer was always an unfortunate "no." No longer! The new PS-1 modular linear power supply is a truly innovative product at an affordable cost.


In the crowded world of linear power supply units, the modular design of the PS-1 is unique. Most power supplies are a fixed voltage and made to power a single product. Some power supplies offer dual (and in the rare instance, more than two) outputs with different voltages. A very rare number of power supplies offer more than one output AND allow the user to select the voltage. Typically, these power supplies are large, heavy and ridiculously expensive. And none, to our knowledge, are truly modular. Enter the PS-1.


  • It's modular and user-friendly
    The beauty of the new PS-1 starts with an emphasis on real value: it's modular design allows up to four devices to be powered at once, and they can even be different voltages! The PS-1 has four power zones in back. Each power zone holds a power module. Each power module can be set to one of four voltages (5v, 9v, 12v, 15v) and can power one device. To change the voltage, simply slide out the module, move the internal switch to the new voltage, and slide it back in. The front panel's LED display instantly tells you which zone(s) and voltages are in use. Additional power modules can be purchased as needed, ensuring that now and in the future, you won't have to worry about powering your devices.
  • It's compact and affordable
    The new PS-1 is just 6.25" x 8.25" x 3.25". Additionally, since it is made out of extremely sturdy but lightweight material, most of the weight comes from it's very robust R-core transformer. Compared to other power supplies the size and weight of some amplifiers, the compactness of the PS-1 makes it extremely easy to place and work with. And at a starting price of $499 with one power module, it's as easy to buy as it is to put in your system rack. 
  • It's awesome
    The PS-1 offers real value and innovation. No longer do you need to pay hundreds of dollars (or more) for a power supply that only powers one device. The PS-1's modularity allows it to grow as your system does. Its price, performance level and real flexibility makes the PS-1 the new standard bearer in power supply units!
