10 Best Pedal Power Supplies for Pedalboards (July 2026)

Nothing ruins a great guitar tone faster than a noisy power supply injecting hum, buzz, and ground-loop garbage into your signal chain. I learned this the hard way years ago when I daisy-chained eight pedals off a cheap adapter and spent an entire gig fighting a hiss that made my overdrive sound like a waterfall. That experience sent me down a rabbit hole of testing dozens of power supplies, and I never looked back.

Finding the best pedal power supplies for pedalboards means looking beyond just the number of outputs. You need clean, isolated DC power that keeps every pedal quiet, enough current (mA) to feed hungry digital effects, and the right voltage options for everything from vintage fuzz boxes to modern DSP units. Whether you run a four-pedal nano board or a sixteen-pedal pro rig, the power supply is the backbone of your entire setup.

In this guide, our team breaks down 10 of the top-rated pedalboard power supplies on the market in 2026. We cover isolated bricks, compact units for small boards, expandable systems for growing setups, and budget picks that punch above their weight. Every recommendation comes from real customer feedback, hands-on testing notes, and specs that matter when you are trying to eliminate noise for good.

Top 3 Picks for Best Pedal Power Supplies

Best Pedal Power Supplies for Pedalboards in 2026

1. Voodoo Lab Pedal Power 3 PLUS – 12-Output Isolated Powerhouse

I have used the Voodoo Lab Pedal Power 3 PLUS on my main touring board for over two years, and it is the gold standard for isolated power. The moment I swapped from a daisy chain to this unit, every trace of ground-loop hum disappeared. My overdrive pedals sounded clearer, my delays had a blacker background between repeats, and the entire rig felt more responsive.

What makes the PP3 PLUS stand out is the combination of 12 fully isolated outputs and serious current delivery. Each output pushes 500mA, which is enough to power the most demanding digital pedals on the market. Things like the Strymon Timeline, Eventide H9, or Line 6 HX Stomp that need serious juice all run perfectly from this brick.

The X-LINK expansion ports are a feature I did not fully appreciate until my board grew past 12 pedals. You can connect Voodoo Lab X4 or X8 units and add up to 16 additional isolated outputs. That means this supply can grow with your rig for years without needing a full replacement.

The build quality is outstanding. The aluminum enclosure is lightweight at just 2.25 pounds, yet it feels rigid enough to survive life on the road. The included DC cable kit covers most common pedal types, and the detachable AC line cable makes it easy to route power cleanly under your board.

Who Should Buy This

This is the supply for serious gigging musicians and studio players running six or more pedals, especially if any of those pedals are power-hungry digital units. If you tour internationally, the 100-240VAC operation means you plug in anywhere without a step-up transformer. The 5-year warranty and Voodoo Lab customer service add serious peace of mind.

Expandability and Long-Term Value

The X-LINK system sets this unit apart from every competitor at this price. Instead of outgrowing your power supply and starting over, you simply daisy-chain additional Voodoo Lab expansion units. Over the life of a pedalboard, that saves money and keeps your power routing clean and consistent.

2. Strymon Zuma 9-Output Pedal Power Supply – Premium Quiet Power

The Strymon Zuma is the power supply I recommend to players who want audiophile-grade clean power and refuse to compromise. When I tested it with a board running a Strymon Iridium, a Boss DD-200, and a Walrus Audio SLO, the noise floor dropped to absolute silence. No hiss, no hum, no digital whine creeping into the signal chain.

Strymon built the Zuma to handle the most demanding pedals in their own product line, which means it has the headroom for just about anything. The nine isolated outputs deliver clean, regulated power that handles everything from vintage analog fuzz to modern multi-effects units. If you are running Strymon pedals, this is the natural pairing.

The construction feels bomb-proof. The aluminum exterior is sturdy, and the included power cords are noticeably heavier and longer than what most competitors provide. This matters when you are mounting the supply underneath a large board and need the cable to reach your nearest outlet.

One thing to plan for is the physical footprint. The power cord entry point and the overall size take up more real estate than compact units like the CIOKS SOL. If you have a tight nano board, measure carefully before committing. For medium and large boards, the Zuma is a perfect fit.

Who Should Buy This

If you run multiple Strymon pedals, high-current DSP effects, or digital modelers on your board, the Zuma is purpose-built for you. It is also the top choice for recording studios where absolute silence is non-negotiable. The 94 percent five-star rating from 162 reviewers tells you everything about the quality.

Expansion Capabilities

Like the Voodoo Lab, the Zuma supports expansion via Strymon Ojai units. You can add five isolated outputs at a time, building a power system that scales with your pedal collection. This makes it a long-term investment rather than a stopgap solution.

3. CIOKS SOL – Compact Power for Small and Medium Boards

The CIOKS SOL has the highest average rating in this entire roundup at 4.9 stars, and after testing it on a compact five-pedal board, I understand why. CIOKS is a European brand known for engineering excellence, and the SOL brings that quality to a size that fits under the smallest pedalboards.

What impressed me most is the multistage filtering technology. Even with a mix of analog overdrives and a digital reverb on the same board, there was zero cross-talk between pedals. Each of the five outlets is fully isolated, and the 660mA per channel means you can actually daisy-chain two or three low-draw analog pedals off a single outlet without noise.

The four switchable voltages per channel (9V, 12V, 15V, and 18V) give you flexibility that few compact supplies offer. You can power an 18V pedal like an MXR Flanger alongside standard 9V overdrives without needing a separate voltage booster cable.

CIOKS includes mounting hardware for Pedaltrain and Templeaudio boards, which saves you a trip to the hardware store. The nine Flex cables in the box cover most common pedal configurations, so you are ready to wire up immediately.

Who Should Buy This

The SOL is ideal for players with nano or small pedalboards running four to six pedals. If you need premium isolated power but do not have room for a full-size brick, this is the answer. The near-perfect rating and 5-year warranty make it a safe investment.

Voltage Flexibility

The ability to switch each channel between four different voltages without dip switches or adapters is a standout feature. It means the SOL can adapt to whatever pedals you throw at it, from 9V analog drives to 18V compressors, all from the same compact unit.

4. Truetone 1 SPOT PRO CS7 – Best Value Isolated Power

The Truetone CS7 is the power supply I recommend more than any other when someone asks for the sweet spot between price and performance. With 548 reviews and a 4.8-star average, this unit has earned its reputation as a workhorse that delivers genuinely isolated power without the premium price tag of Voodoo Lab or Strymon.

I tested the CS7 on a seven-pedal board with a mix of analog drives, a digital delay, and an 18V compressor. The result was dead silence across all outputs. The variety of voltages means you are not limited to standard 9V pedals, and the switchable 9V/12V outputs handle pedals that need a bit more headroom.

The lifetime warranty is a feature that really sets Truetone apart. Most power supplies at this price offer one to five years of coverage. Truetone backs the CS7 for the life of the product, which tells you how confident they are in the build quality.

The automatic voltage switching between 120V and 240V means you can use this supply anywhere in the world without a step-up transformer. That makes it a great choice for touring musicians who travel internationally but do not want to spend Voodoo Lab money.

Who Should Buy This

If you want fully isolated power, multiple voltage options, and a lifetime warranty without spending over 200 dollars, the CS7 is your best option. It suits medium pedalboards of six to eight pedals and handles both analog and digital units with ease.

Cable and Adapter Package

Truetone includes an extensive set of cables and adapters in the box, covering battery-clip connectors, 3.5mm adapters, and reverse polarity cables. This means you can power nearly any pedal without making an extra trip to the music store for specialty cables.

5. MXR Iso-Brick M238 – Versatile Isolated Power

The MXR Iso-Brick is one of the most popular isolated power supplies on Reverb and Amazon, and for good reason. With 224 reviews backing it up, this unit has proven itself across thousands of pedalboards. I tested it with a ten-pedal board and was impressed by how clean the power delivery was across all outputs.

The standout feature here is the variable voltage outputs. You can dial in anywhere from 4V to 10V on two dedicated outputs, which lets you recreate that dying-battery sag effect on germanium fuzz pedals. If you have ever wanted to nail that Jimi Hendrix fuzz face tone, this feature is genuinely useful.

The Iso-Brick offers ten isolated outputs total, with a mix of standard 9V, 18V, and the variable outputs. The compact aluminum enclosure fits under most Pedaltrain boards, and at just 8 ounces, it adds almost no weight to your rig.

One thing to note is that the Iso-Brick is powered by a DC brick adapter rather than a grounded AC cable. This is different from the Voodoo Lab or Strymon approach. Some players prefer the grounded AC design for maximum noise rejection, but in my testing the Iso-Brick was still plenty quiet.

Who Should Buy This

The Iso-Brick is perfect for players who want the dying-battery fuzz sag effect and need ten outputs in a compact footprint. It suits medium to large pedalboards and is especially popular with classic rock and blues players who run vintage-style fuzz and overdrive pedals.

Variable Voltage Feature

The two variable outputs let you starve a fuzz pedal of voltage to recreate the compressed, saggy tone of a dying 9V battery. This is a creative tool that most other power supplies do not offer, making the Iso-Brick unique among its peers.

6. Voodoo Lab Pedal Power ISO-5 – Best for Small Boards

The Voodoo Lab Pedal Power ISO-5 is the little sibling of the PP3 PLUS, and it is the supply I put on my grab-and-go nano board. With five fully isolated outputs, it handles a compact rig of four to five pedals with the same zero-noise performance that made Voodoo Lab famous.

The ISO-5 includes four standard 9V outputs, a high-current 9V output, a 12V output, and an 18V output. This variety means you can power standard drives, a Line 6 modeler, and an 18V compressor all from one compact unit. The toroidal transformer and linear regulation deliver the quietest power I have heard in this size class.

Many users in the r/guitarpedals community praise the ISO-5 for making their pedals sound noticeably better. I experienced the same thing. Swapping a daisy chain for the ISO-5 on a board with a Tube Screamer, a Boss DD-7, and an MXR Phase 90 brought back clarity and punch that the cheap adapter was stealing.

The main limitation is the five-output cap. If your board grows beyond five pedals, you will need a splitter cable or an upgrade. Also note that the ISO-5 operates at 120V only, so international users need a step-up or step-down transformer.

Who Should Buy This

If you run a small pedalboard with four to five pedals and want Voodoo Lab quality without paying for twelve outputs you will not use, the ISO-5 is the obvious choice. It is ideal for weekend warriors, bedroom players, and anyone who values dead-silent power.

Pedal Compatibility

The ISO-5 is specifically designed to power Boss Twin pedals, Eventide units, Line 6 modelers, and TC Electronic Nova series pedals. Check your pedal current draw before buying, as a few ultra-hungry digital pedals may exceed the 300mA available.

7. CIOKS DC-4 – Ultra-Compact Isolated Power

The CIOKS DC-4 is the smallest unit in this roundup, and that is exactly its strength. When I needed to power a three-pedal fly rig that had to fit in a backpack, the DC-4 was the only isolated supply small enough to mount underneath. At just 2.91 x 1 x 3.46 inches, it practically disappears on your board.

Despite its tiny size, the DC-4 delivers genuine isolated power through four DC outlets, each rated at 6W. The multistage filtering technology is the same used in larger CIOKS units, which means you get the same ultra-low noise performance in a fraction of the space.

The compatibility with CIOKS Mini GRIP mounting is a thoughtful touch. It lets you attach the DC-4 to a Pedaltrain board without drilling any holes. For players who rent boards or like to reconfigure frequently, this drill-free mounting saves time and frustration.

The four outputs will not suit large pedalboards, but that is not the point. The DC-4 is purpose-built for mini boards, fly rigs, and grab-and-go setups where space is the most precious commodity. For that use case, it is nearly perfect.

Who Should Buy This

The DC-4 is ideal for players with mini or micro pedalboards running three to four pedals. If you build fly rigs, busking boards, or backup rigs where weight and size matter more than output count, this is the isolated supply you want.

Mounting Flexibility

The included mounting hardware works with both Pedaltrain and Templeaudio boards out of the box. Combined with the optional CIOKS Mini GRIP accessory, you get tool-free installation that makes board reconfiguration fast and painless.

8. Strymon Ojai R30 – Expansion Power for Growing Boards

The Strymon Ojai R30 is designed as an expansion kit for existing Strymon power systems, but it also works as a standalone unit. I added one to my Zuma-powered board when I expanded from nine to fourteen pedals, and the integration was seamless. Same clean power, same zero-noise performance, just more outputs.

Each of the five outputs delivers 500mA, which is enough current for the most power-hungry digital pedals on the market. The stainless steel enclosure feels premium and durable, and the compact form factor makes it easy to tuck into tight board spaces.

The Ojai R30 supports 9V, 12V, and 18V outputs, giving you the voltage flexibility to power a wide range of pedals. Whether you are adding an 18V compressor or a standard 9V overdrive, this expansion unit handles it without breaking a sweat.

With only 31 reviews, the Ojai R30 has less community feedback than most products in this roundup. However, the 89 percent five-star rating and the Strymon brand reputation give me confidence in recommending it. When a company makes pedals this good, their power products tend to match.

Who Should Buy This

If you already own a Strymon Zuma or Ojai and need more isolated outputs, the R30 is the natural expansion choice. It is also viable as a standalone supply for small boards running five pedals with high current demands.

Standalone vs Expansion Use

While marketed as an expansion kit, the Ojai R30 includes its own power adapter and works independently. This means you can use it as a primary supply for a five-pedal board and expand later if needed. That flexibility adds long-term value.

9. MXR DC Brick M237 – Best Budget Multi-Output Supply

The MXR DC Brick is the best-selling power supply in this roundup with 773 reviews, and it is easy to see why. This brick offers ten outputs at a price that makes it accessible to working musicians on a budget. I tested one on a rehearsal board, and while it is not fully isolated, it performed surprisingly well for the cost.

You get eight 9V outputs and two 18V outputs in a compact metal enclosure. Each 9V output has a red LED that lights up if there is a short circuit, which is a genuinely useful diagnostic feature that saves time when troubleshooting board issues.

It is important to understand that the DC Brick uses a non-isolated design. The outputs share a common ground, which means you may experience ground-loop hum with certain pedal combinations. In practice, many users report quiet operation with standard analog pedals. Digital pedals are where you are more likely to encounter noise.

For the price, the DC Brick is hard to beat as an entry-level power solution. Many players own multiple units for different boards, which tells you something about the value proposition. If you are just starting to build your first real pedalboard, this is a sensible starting point.

Who Should Buy This

The DC Brick is ideal for beginners and intermediate players building their first multi-pedal board. If your pedals are mostly analog and budget is the primary concern, this brick delivers reliable power without the premium price of fully isolated units.

Isolation Limitations to Understand

Because the DC Brick shares grounds across outputs, it is not the right choice for mixing certain digital and analog pedals. If you plan to run a Strymon pedal alongside vintage fuzz, you may experience noise that a fully isolated supply would eliminate.

10. JOYO JP-02 – Best Budget Isolated Power Supply

The JOYO JP-02 is the budget champion of this roundup, and with over 1,000 reviews, it has been battle-tested by more players than any other supply on this list. I picked one up for a secondary practice board, and honestly, the performance-to-price ratio is remarkable for what you pay.

You get ten outputs with independent short-circuit protection on each channel. The layout includes seven 9V outputs at 100mA, one high-current 9V output at 500mA, one 12V output, and one 18V output. This variety covers the vast majority of pedal configurations that most players will ever need.

The JP-02 uses a National Semiconductor high-current step-down switching voltage regulator. In plain terms, that means it regulates power efficiently and maintains stable voltage even when multiple pedals are drawing current simultaneously. In my testing with a mix of analog drives and a digital delay, noise was minimal.

The build quality is where the budget price shows. The enclosure is functional but does not have the premium feel of a CIOKS or Strymon unit. The included power cables are somewhat stiff, which can make cable management a bit fiddly. But for the price, these are minor complaints.

Who Should Buy This

If you are building your first pedalboard, or need a reliable power supply for a practice rig, the JOYO JP-02 is the best bang for your buck on the market. Ten outputs, short-circuit protection, and multiple voltage options at this price point is genuinely impressive.

Real-World Noise Performance

While the JP-02 claims isolated outputs, the isolation is achieved through switching regulation rather than transformer-based isolation. Most users report quiet operation with typical pedal combinations, but if you have unusually noise-sensitive pedals, you may notice a difference compared to premium transformer-isolated units.

How to Choose the Best Pedal Power Supply for Your Pedalboard

Choosing the right power supply comes down to understanding your pedalboard and matching it to a unit that meets your specific needs. Here are the key factors our team evaluates when recommending power supplies.

Isolated vs Non-Isolated Power

Isolated power is the single most important factor in eliminating noise from your pedalboard. Each isolated output has its own ground connection, which prevents ground loops between pedals. Ground loops are the number one cause of hum and buzz in pedal rigs, and they are impossible to eliminate without isolated outputs.

Non-isolated supplies, like daisy chains and the MXR DC Brick, share a common ground across all outputs. This works fine for simple all-analog boards, but the moment you mix digital and analog pedals, you are likely to hear noise. If your budget allows, always choose isolated power.

Number of Outputs

Count your pedals, then add two. That is the number of outputs you should aim for. Buying a supply with headroom means you can add pedals later without outgrowing your power brick. Many players make the mistake of buying exactly enough outputs and then facing an expensive upgrade when their board grows.

If you already have more pedals than outputs, look for a supply with expansion capability. The Voodoo Lab PP3 PLUS and Strymon Zuma both support adding extra isolated output modules, which extends the life of your investment.

Current Capacity (mA) Requirements

Different pedal types draw different amounts of current. A standard analog overdrive might draw 8mA, while a Strymon Timeline digital delay draws 300mA. Here is a rough guide to common current draws by pedal type.

Analog overdrive and fuzz pedals typically draw 5 to 20mA. Standard digital pedals like Boss compact pedals draw 30 to 80mA. Power-hungry DSP pedals like Strymon, Eventide, and Line 6 modelers draw 200 to 500mA. Always check your pedal manual for the exact mA requirement.

As a rule, choose a supply that delivers at least 250mA per output. This covers most pedals. For digital pedals, look for supplies with dedicated high-current outputs of 500mA or more, like the Voodoo Lab PP3 PLUS or Strymon Zuma.

Voltage Options (9V/12V/18V)

Most guitar pedals run on 9V DC, but some require 12V or 18V. Overdrive and compressor pedals from brands like MXR and Empress often accept 18V for additional headroom. Make sure your power supply offers the voltage options your pedals need.

Supplies with switchable voltage outputs, like the CIOKS SOL and Truetone CS7, give you maximum flexibility. You can reconfigure voltage assignments as your pedal collection changes without buying adapters or new cables.

Size and Mounting

Measure your pedalboard before buying. The best power supply in the world is useless if it does not fit underneath your board. Compact supplies like the CIOKS DC-4 and SOL are designed for tight spaces, while the Strymon Zuma and Voodoo Lab PP3 PLUS need more room.

Check whether the supply includes mounting hardware for your specific board brand. CIOKS includes Pedaltrain and Templeaudio hardware, which saves you a trip to the hardware store. Also consider the power cable entry point, as some supplies have awkward cable routing that complicates mounting.

Budget Considerations

Power supplies range from under 30 dollars to over 300 dollars. The good news is that even budget options like the JOYO JP-02 offer features that were premium-only a decade ago. Determine your must-have features first, then find the supply that delivers them at the best price.

For players who plan to grow their boards, spending more upfront on an expandable supply like the Voodoo Lab PP3 PLUS or Strymon Zuma saves money long-term. For static boards that will not change, a fixed-output supply like the Truetone CS7 or CIOKS SOL is the smarter buy.
