Identifying the best pedalboard power supply for your setup might not rank among the most exciting aspects of building your rig, but the right unit goes a long way toward facilitating some of those more fun parts of gear acquisition - namely, adding new pedals to your effects line-up.

In fact, as your pedalboard grows, you’ll find that a good power supply is a necessity. As the number of effects in your rig increases, it will become clear that merely daisy-chaining all your pedals together will lead to increased hum or buzz. The benefit of a power supply—and in particular a supply with isolated outputs—is noise reduction in your signal chain and a cleaner, more intuitive pedalboard operation overall.

Isolated outputs also ensure that the current delivered to a pedal is consistent, which helps when dealing with distinctions between lower-draw effects and more powerful digital stompboxes and multi-effect units.

As with anything else in the gear world, there’s plenty of variety to be found in the power supply market, from size to features to price point. With that in mind, Guitar World offers up this list of 10 of the best pedalboard power supplies available today.

Outputs have specific uses that might not be convenient in every situation

The Iso-Brick boasts 10 outputs, making it possible to run a wide range of pedals with noise-free DC power. The outputs are fully isolated and extremely quiet, and accommodate a variety of voltage and current requirements—two 9V outputs at 100mA, two 9V outputs at 300mA, two 9V outputs at 450mA, two 18V outputs at 250mA and—in one particularly cool feature—two 6-15V variable voltage outputs that can emulate voltage “sag.”

Beyond just doing its job—and rather well, we might add—the Iso-Brick offers additional thoughtful touches, including a recessed, right-angled power cable for easy pedalboard placement and glowing LED indicators on each output to keep the user up to speed on the status of the connected pedal. It all adds up to a pedalboard power supply that will quickly become an essential part of your 'board's operation.

2. Strymon Ojai

Small box, big power

Launch price: $149/£149.95 | Type: Isolated power supply | Isolated outputs: 5 | Switchable voltage: Automatic | Weight: .29 pounds | Features: Chain additional units

500mA current on each output
Ojai units can be chained together
Automatic worldwide power compatibility 
Separate, laptop-style power supply

The Strymon Ojai is a powerful, compact box offering five high-current outputs that offer a massive 500mA on each output. The five outputs are also individually isolated, ultra-low-noise and have their own dedicated regulators and custom transformers. And if five isn’t enough, additional Ojai units can be added on via a 24V Thru jack, without the need to plug into a wall outlet.

There’s also two stages of isolation, eliminating ground loop and AC line noise issues, as well as automatic worldwide power compatibility for ease of use on stages anywhere in the world. What’s more, the Ojai comes in a low-profile R30 version for smaller boards, as well as a larger, nine-output Zuma model (the Zuma, meanwhile, also comes in its own low-profile iteration, the R300).

3. Mooer Macro Power S8

The best pedalboard power supply for partially isolated power on a budget

Launch price: $98/£79 | Type: Partially isolated power supply | Isolated outputs: 4 | Outputs: 4 | Switchable voltage: Yes | Weight: 2.47 pounds | Features: 1 9/12/15/18V DC 200mA output

Competitively priced
LED indicators 
Voltage switching for worldwide use
Only four isolated outputs

The Macro Power S8 boasts a combination of eight isolated and non-isolated outputs—one switchable 9V, 12V, 15V and 18V at 200mA, three independent 9Vs at 200mA and four parallel 9Vs that share a total of 400mA. 

While the non-isolated 400mA isn’t a huge amount, it’s substantial enough to handle most digital pedals. If not, there’s a handy LED that switches off when a pedal requires more power than the output has available. There’s also overcurrent protection and voltage switching for worldwide use, making the Macro Power a versatile and extremely handy unit—especially at its price point.
