Roland Power Adapter Lookup Tool & Where to Purchase

When a customer asked me what power adapter they should buy for their Roland FP-90X, I figured it’d be a quick lookup. A few minutes later, I was elbow-deep in Roland service manuals, product listings with conflicting voltage specs. Some sellers offered “compatible” power supplies at both 9V and 12V. (There’s some incorrect information on the internet—it’s true!) So I found some reference documents and built this simple lookup tool.

Using the power adapter tool

Just type in any Roland model number and instantly see the correct power adapter.

I’ve included links to the least expensive Roland branded power adapters I could find, variously from Roland, Sweetwater, Thomann, and B&H. I wasn’t able to find some international models, and those links won’t go anywhere—please contact me if you have decent suppliers.

It only starts searching after you’ve typed at least 2 characters. Dashes are ignored, so typing FP30X works the same as FP-30X. If there’s no match, it says so right away.

And while we’re at it, since you’re replacing your power adapter, you should seriously consider an insured surge protector!

Generic and universal adapters on Amazon

Do not buy generic power adapters unless you have no other choice. There are dozens of generic power adapters online that claim to work with your Roland keyboard or pedal. But if you care about the longevity of your instrument, don’t do it!

As a technician, I’ve worked on multiple keyboards that came in with dead main boards or strange behavior, only to find a sketchy adapter. Inexpensive power adapters can supply incorrect voltages, can get fire hot, or can cause ripple and oscillation. I’ve seen lousy power adapters, even when they “work,” introduce buzzing in the speakers and screen flickering. Don’t grab a $15 adapter on Amazon just because it fits in the hole. Buy the real thing!

Current purchase links for common adapters

Here are my current purchase links for the ACN-120, PSB-1U, PSB-7U, PSB-4U, PSB-12U, PSA-230S, PSB-5U, PSB-14U, PSB-120, PSB-13U, and PSD-230.

Please note that the PSB-1U is the same adapter as the PSB-120 and the ACK-120. If you have either of these adapters, you can safely replace it with the PSB-1U.

If you’re searching for an ACN‑120 / PSB‑4U / PSB‑4UREPL, please see my article on the modern solution for replacing these discontinued adapters.

Similarly, if you’re searching for a PSB-3U, it has been replaced by the PSB-7U.

The PSB-18U is currently available only through Roland dealers. You’ll have to reach out to your nearest Roland dealer or service center to get one.

Some adapters ship with the wall power cord sold separately. If your instrument uses a fixed power cord (no external adapter), the lookup tool above is the best place to confirm.
