Boss PSA-230ES Power Supply for Boss Compact Pedals
The Boss PSA-230ES Power Supply is the quiet hero of countless pedalboards — simple, dependable, and built to keep your rig running exactly as it should. It might not be the flashiest bit of gear, but it’s one of the most important.
Designed specifically for Boss compact pedals, the PSA-230ES delivers clean, stable 9V DC power, ensuring your effects sound consistent and noise-free. Whether you’re running a single pedal or daisy-chaining a small setup, it provides the kind of reliability you don’t have to think twice about.
One of the big upgrades with this model is its high current capacity (500mA), making it suitable not just for standard stompboxes, but also for more modern digital pedals that need a bit more power under the hood.
It’s also built with efficient, low-noise circuitry, helping to minimise hum and interference — something you’ll definitely appreciate when you’re playing live or recording.
Compact and lightweight, it fits neatly into any setup, and the long cable length gives you flexibility when positioning your pedals and power source.
This is the kind of piece that just quietly does its job, day in, day out — no drama, no issues, just consistent performance.
