A BOSS Power Supply Designed for Daily Reliability
The BOSS PSA-230P is a power adapter designed to meet the demands of musicians using effects pedals in rehearsal, on stage, or in the home studio. Positioned as a simple and safe solution within the Boss ecosystem, this power supply prioritizes current stability to preserve your effects' performance and prevent unexpected cutouts caused by unsuitable power sources.
Who Is It For and What Are Its Uses?
This power supply is ideal if you want to replace batteries, secure your setup, and gain peace of mind during long playing sessions. It is intended for guitarists and bassists equipped with 9V effects pedals, as well as musicians seeking a reliable solution to power a compatible pedal, including other brands, provided the electrical specifications are respected.
Clean Voltage for Your Effects Pedals
Designed to deliver a 9 Volt direct current up to 500 mA, the PSA-230P offers a stabilized, regulated, and filtered power supply-a crucial feature in audio to reduce unwanted noise and maintain a clean signal. The negative center polarity corresponds to the most common standard for effects pedals.
Compatibility: A Point to Check Before Plugging In
As with any pedal power supply, always verify the voltage (9V), the polarity (center negative), and the required amperage of your equipment. The PSA-230P should not be used with pedals requiring more than 500 mA of current.

Questions frequently asked
Is the Boss PSA230s compatible with a 9V negative center pedal?
This power supply provides 9 V DC with a negative center and positive outer polarity. Compatibility depends on the pedal's current draw not exceeding 500 mA.
What is the maximum current output of this BOSS power supply?
The output delivers up to 500 mA, or 0.5 A. A pedal requiring a higher amperage should not be connected to it.
Can it reduce power supply noise on an effects pedal?
The stabilized, regulated, and filtered design is intended to deliver clean 9 V DC voltage. This type of power supply helps limit unwanted noise caused by an inadequate power source. The effect's behavior is thus preserved during long sessions.
Does this power supply work with a French power outlet?
The input is designed for 230 V AC at 50 Hz, matching the French electrical grid.
Can a guitar or bass pedal be powered with this power supply?
It is suitable for 9 V effects pedals used by guitarists and bassists, provided the negative center polarity and the 500 mA limit are respected.
