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.

Boss power supply for Boss pedal.
It works well, it delivers 9V and dust well.

I didn't notice any buzz.

This power supply delivers 0.5A (500mA)

The olive on the wire is not (contrary to what one might think, and what one writes other well-known websites) a switch, but rather an anti-parasite “ring” (against buzzes, not against cockroaches...)

Moral: you have Boss pedals, do you care, do you want a power supply? Forget the price and buy a Boss power supply, you will save your pedals and save your batteries;]

Play economy and take another cheaper brand is not always a good idea, or else I advise you to check with the multimeter before plugging in, it avoids disasters like my previous cheaper power supply, sold for 9V which gave more than 13V, with a hell of a buzz... if I hadn't checked before, I would have plugged in and let my pedals burn out quietly, and given the price of the pedals, it's better to have a PSU that ensures their lifespan :-)

I was lucky to have offered it with the purchase of a BOSS pedal otherwise I would not have bought it but now I absolutely do not regret it, firstly its very practical length on stage no need for a multi extension etc... secondly its quality, I plugged it into a BOSS that's why I don't know about any other brand but almost total silence, no breath, no buzz, very resistant I even recommend it for this price

As usual, when it comes to delivery and packaging, it's top notch at woodbrass. Perfect Regarding the equipment, works very well with my BR 600... after that it remains a mains power supply... Even with the price drop, 29 euros for a PSU, a bit expensive for my taste. But hey, that's what I wanted and so... Thanks again Woodbrass

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.
