BOSS PSA-120S Power Supply
- Power cable length is increased to almost 10 feet
- New design which does not cover adjacent power outlets
The PSA series is the recommended power supply for products including all new BOSS compact and Twin pedals, multi-effects and more. The PSA series power adapters provide 500 mA of current to easily power multiple pedals, even digital ones, with an LED indicator for quick visual verification of on/off status.

It’s great, has high quality, easy to use and powers the pedal nicely. But the price… WAY too much for just a power cable. I will be returning this to buy a pedalboard power supply.

I bought this power adapter to power my Roland SPD:ONE WAVE. I use it for live performances, and it has not let me down. The length of the cord is just right, and I always have plenty of slack, even when the power plug is relatively far away. It fit perfectly and snug in the sample pad, and it has not fallen out. They box is a little weak, but that might be user error. I was in a rush when I was first unpacking it, so I must have pulled too hard and ripped it, but it's not really a big deal as the power adapter itself comes in a plastic bag. If I ever need another one, im coming right back here to buy it again. Highly Recommend

By coincidence, I got both a Boss looper and ME-80 multi-effects unit at about the same time. Roland has cut corners (oddly) lately by designing everything to run on battery power--good--but also being able to run on their "optional" PSA AC adapter. Which is $30. I bought a cheap after market compatible adapter for the looper at a third of the price, and this for the ME-80. Both work flawlessly and I can't tell the difference sound-wise. Is this one worth three times the price? I don't know. But I admit I worry a bit less about it, even though they both say "Made in China". This one is clearly better built and shielded...

This product is exactly what's needed for the boss VE22. The problem I have is for the cost of the boss VE22 this item should be included.

My cool new Boss SY-200 had audible line noise. It was daisy-chained on a 2-amp wall adapter, with a Mooer Red Truck multi-pedal and a Boss CE-5 chorus pedal. I figured the noise might go away if I gave the SY-200 its own power, and sure enough this adapter does the trick -- the noise is gone, baby. Yes, it's pricey, but it has that nice current protection feature, and hey -- does saving ten bucks matter, for a $300 pedal?Specs: This adapter is 500mA. The SY-200 draws 230 mA, so there's power left over for analog pedals, if you want it -- but watch out for noise.Bottom line: plenty of power for the Boss SY-200, and it cleaned up the line noise perfectly. A digital pedal needs isolated power, period.Update: I bought more pedals (who doesn't?), and upgraded to the Ghost Fire GP8-SV2 isolated power supply. It words perfectly, despite my reservations about lack of warranty (see my review).

Does what it should and no problems. The ONLY reason it doesn't get 5 stars is because I don't know how long it'll last.

I don't know what it is, but I feel like when I use this power adapter, I get a better sound through my amp. Which I didn't think would be the case, I thought why not just use a One Spot? If you have Boss equipment and want a solid power source, I'd get this.

The recommended adapter for most Boss products. I got it for my Boss DB-90 Dr. Beat Metronome. Now no worries about batteries. It is well built and hardy product. An original Boss. Highly recommended for professional musicians and students.

Excelente producto. Fue el mejor precio que encontré y es de alta calidad. Lo recomiendo si quieres cuidar tu pedal, no compren genéricos, esto es lo que tu equipo necesita.
