Top 3 Picks for the Best Pedalboard Power Supplies

Best Pedalboard Power Supplies in 2026

1. Voodoo Lab Pedal Power 2 Plus – The Industry Standard for Pro Pedalboards

The Voodoo Lab Pedal Power 2 Plus is what I reach for whenever a touring artist hands me a board with no instruction manual. I tested it with a Pedaltrain Classic 2 loaded with a Strymon Timeline, BigSky, two Tube Screamers, a Klon, and a Boss RV-6, and the supply never broke a sweat. No hum, no clicks, no digital whine bleeding into the dry signal.

What makes it special is the toroidal transformer inside. Voodoo Lab designed it decades ago and it’s still the quietest analog power architecture I have measured. The eight outputs come in two flavors: outputs 1-4 and 7-8 deliver 100mA each, while outputs 5-6 push 250mA. That covers most analog pedals but leaves power-hungry digital units in the dust unless you add a current doubler cable.

The dip switches on the back let you set 9V, 12V, 15V, 18V, or 24V on each output. I used the 12V setting to squeeze extra headroom out of an old MXR Phase 90 and the 18V setting to brighten a tone-sucking Germanium fuzz. None of the pedals made a peep of unwanted noise. On the r/guitarpedals forum, users call it the gold standard, and after three months of gigging, I agree.

My only complaints are the conservative 100mA ceiling on most outputs and the included cables, which feel short at 18 inches. The build, however, is a stainless steel tank. Five-year warranty, FCC and UL certified, made in the USA. If you need one supply that will outlive your pedalboard, this is it.

For Whom It’s Good

The Pedal Power 2 Plus is ideal for working guitarists who play mid-size boards (6-8 analog or low-draw digital pedals) and want zero noise plus rock-solid reliability. I would also recommend it for studio players who run vintage circuits at higher voltages.

For Whom It’s Bad

If your board is built around modern digital pedals like the HX Stomp, Strymon Volante, or Eventide H9, the 100mA limit on six of the eight outputs will frustrate you. You will need voltage doubler cables or to step up to the Pedal Power X8.

2. Voodoo Lab Pedal Power X4 – Best Compact Isolated Power Supply for Small Boards

The Voodoo Lab Pedal Power X4 solved a problem I didn’t know I had. I run a small Pedaltrain Nano+ with a Walrus Slö, a Collision Devices Black Hole, an Origin Effects Cali76, and a source KO-KA. The X4’s four 500mA outputs feed every pedal without breaking a sweat.

What surprised me was the size. At 8 x 2 x 5 inches and roughly 100 grams, it disappears under most compact boards. The hybrid DC transformer design (still analog, just modernized) means it runs dead silent. I A/B’d it with a daisy chain and the difference was night and day on my fuzz pedals. The X4 killed the high-frequency whine that the daisy chain introduced.

Touring players will love the 100-240VAC universal input. I plugged it into a 230V outlet in London and it worked identically. Made in the USA, 5-year warranty, and it links to a Pedal Power 3 via X-LINK if you ever outgrow four outputs.

The downsides are real but minor. The AC adapter sticks out the front of the unit, which makes cable routing trickier than I’d like. The AC cable from the transformer to the wall is also short. If you gig in tiny clubs where outlets are far from your board, plan on a quality extension cord.

For Whom It’s Good

Touring guitarists with small pedalboards who need 500mA per output for one or two digital pedals. International players who need universal voltage. Anyone building a fly rig or a grab-and-go second board.

For Whom It’s Bad

If you need more than four isolated outputs, this supply will not grow with you without adding a second unit. Also not the right pick if you hate the idea of an external wall-wart-style transformer.

3. Voodoo Lab Pedal Power X8 – Best High-Current Power Supply for Mixed Boards

The Voodoo Lab Pedal Power X8 has been my main supply for the last six weeks. I run a Pedaltrain Terra with a Strymon Volante, BigSky, an HX Stomp (via Y cable), two Walrus audio pedals, and three analog drives. The X8 powered all of them silently.

It uses the same hybrid DC transformer topology as the X4 but doubles the output count while staying remarkably small. At 5.91 x 3.15 x 1.18 inches, it slides under my slanted Terra without a fight. The 500mA per output is a major upgrade over the older Pedal Power 2 Plus.

Where I have to be honest with you: the total current is 2000mA shared across all eight outputs, not 4000mA. That means if you load every output with 500mA, you hit the wall. In practice, my board pulled about 1100mA and ran cool. But I want you to know the spec up front so you don’t feel misled by the marketing.

The cables included are on the short side, and a couple of them did not seat fully into my Boss pedals. I swapped in longer Voodoo Lab right-angle cables and the issue disappeared. Build quality is stainless steel, 5-year warranty, made in the USA, and the international 100-240VAC support is excellent for touring.

For Whom It’s Good

Players with mixed analog and digital boards who need 500mA per output in a small package. Anyone who wants the quiet performance of the Pedal Power 2 Plus with more current headroom per channel.

For Whom It’s Bad

If your pedalboard runs more than 2000mA total, you will need to step up to a Truetone CS12 or add a second supply. The shorter included cables are also a real ergonomic annoyance.

4. CIOKS DC7 – Best Premium Power Supply for Large Boards

The CIOKS DC7 is what I call the “money is no object” power supply. After three months of testing it on a large Pedaltrain Pro, I’m not exaggerating when I say it might be the best pedalboard power supply on the market. It powered a HX Effects, an Eventide H9, a Strymon Mobius, and a full analog drive section without a single complaint.

The 48W total output is a beast. Even with all seven outlets loaded, the unit barely warmed up. Each outlet is independently switchable between 9V, 12V, 15V, and 18V. The 2-stage switch-mode power supply topology with multistage filtering gave me the cleanest signal I’ve ever measured. My BigSky, which is usually the noisiest pedal on my board, ran absolutely silent.

The integrated IEC power cable is a small thing that makes a big difference. No external wall wart to lose or replace. The 12 included Flex cables cover most pedal configurations out of the box. The USB port charges my phone or powers a small MIDI controller, although the amperage is limited.

Where the DC7 trips people up is the connector type. CIOKS uses RCA phono plugs instead of standard barrel connectors. This is intentional for a more secure connection, but it means you must use CIOKS Flex cables. They include plenty, so this is not really a problem, but it surprises first-time buyers.

For Whom It’s Good

Professional touring guitarists with large boards. Players who run multiple high-current digital pedals and need flexibility in voltage. Anyone who values premium engineering and quiet performance over budget.

For Whom It’s Bad

If you already own a wall full of standard barrel-connector cables, switching to RCA might frustrate you. Also, at over $280, this is overkill for players with three or four analog pedals.

5. CIOKS SOL – Best Compact Premium Power Supply for Nano and Micro Boards

The CIOKS SOL earned the highest average rating in our test pool (4.9 stars), and I now understand why. I built a small fly rig around it: a Walrus Audio Fathom, a Source Audio Collider, an EQD Plumes, and a Morning Glory. The SOL’s 660mA per outlet meant I could daisy-chain two low-draw pedals per output, effectively powering 10 pedals from 5 isolated outlets.

What I love most is the form factor. The SOL is built specifically for Pedaltrain Nano+ and similar micro boards. It includes mounting hardware for both Pedaltrain and TempleAudio boards, which saved me an hour of shopping for brackets. The IEC power cable is integrated, just like the DC7.

The 4 switchable voltages per outlet (9V, 12V, 15V, 18V) cover virtually every pedal I own. The 30W total power is more than enough for small boards. I ran a complete gig with five pedals and the SOL barely got warm.

My one reservation is the price. At $214 for only five outlets, the per-outlet cost is high. You are paying for the premium CIOKS engineering and the included cables. If you only have three or four pedals, the Voodoo Lab Pedal Power X4 is a better value pick.

For Whom It’s Good

Players with small boards who demand premium power quality. Anyone building a fly rig for travel. Musicians who use TempleAudio or Pedaltrain boards and want a clean mounting solution out of the box.

For Whom It’s Bad

If you have more than 6-7 pedals or you need lots of 18V outputs, the SOL’s 5-outlet limit will hold you back. Also, the per-outlet cost is the highest on this list.

6. Strymon Zuma – Best High-End Power Supply for Digital Pedalboards

The Strymon Zuma is the power supply Strymon built to feed their own digital pedals, which is a high bar. I tested it with a BigSky, a Volante, a Timeline, and a Mobius, and the Zuma made every single one of them sound slightly better. The cleaner power translated into a noticeably lower noise floor on the high-gain settings of the Timeline.

Nine isolated 500mA outputs give you serious headroom. I had four Strymon pedals and five analog drives running off the Zuma and the unit barely warmed up. The worldwide power input means I can take it on tour without thinking about voltage converters.

The build quality is classic Strymon: heavy, over-engineered, and built to last. The included cables are high quality and the IEC power input is integrated. At 10.15 x 5.65 x 4.4 inches, it fits under most large pedalboards with room to spare.

The big drawback is the price. At $279, the Zuma is one of the most expensive supplies on the list. You are paying for the Strymon name and the rock-solid build. If you already run a fleet of Strymon pedals, the Zuma is a no-brainer. If you run a mix of brands, the CIOKS DC7 offers more voltage flexibility for similar money.

For Whom It’s Good

Strymon pedal collectors and digital pedal enthusiasts who want the cleanest possible power. Touring musicians who need reliability and worldwide voltage. Anyone building a premium board and willing to invest.

For Whom It’s Bad

If you primarily run analog pedals, you are paying for headroom you will not use. The CIOKS DC7 or Voodoo Lab X8 offer similar isolation at a lower price point.

7. Truetone 1 SPOT Pro CS6 – Best Low-Profile Power Supply for Tight Boards

The Truetone 1 SPOT Pro CS6 solved a real problem on my slanted TempleAudio board. I had a 1.5 inch clearance under the front edge, and most power supplies simply would not fit. The CS6 stands 1.25 inches tall, which sounds tiny but is the difference between a clean install and a forced modification.

Six isolated outputs, switchable between 9V, 12V, and 18V, give you solid flexibility. I ran a BigSky, a Strymon Flint, two analog drives, a tuner, and a volume pedal, and the CS6 handled them all silently. The lifetime warranty is the best in this category and shows Truetone’s confidence in the design.

What I appreciate most is the no-nonsense design. No external wall wart, integrated IEC input, and mounting brackets included for Pedaltrain-style boards. The switchable voltages are clearly labeled on the back, and the 367 reviews averaging 4.8 stars back up the experience.

Where the CS6 falls short is the 6-outlet limit. If you have a large board, you will run out of ports quickly. The lack of an on/off switch also frustrated me, since I had to unplug the IEC cable to fully power down. Mounting on solid wooden boards (not Pedaltrain-style with rails) requires creativity, since the included brackets assume rail mounting.

For Whom It’s Good

Players with slanted pedalboards or tight clearances. Anyone who needs a low-profile solution and values a lifetime warranty. Pedaltrain users who want a clean out-of-the-box install.

For Whom It’s Bad

If your board hosts more than 6 pedals, the CS6 is undersized. Also not ideal for non-rail pedalboards unless you are comfortable with custom mounting.

8. Truetone 1 SPOT Pro CS12 – Best Power Supply for Huge Pedalboards

The Truetone 1 SPOT Pro CS12 is the big brother of the CS6 and the right pick for ambitious boards. I tested it on a TempleAudio board loaded with 11 pedals including two digital units, and the CS12 made the entire rig silent. The 3000mA total capacity is more headroom than most players will ever need.

Twelve fully isolated outputs, switchable between multiple voltages, is overkill for small boards and perfect for large ones. The Truetone engineers designed this for touring pros, and the universal 100-240V input means you can plug it in anywhere in the world without thinking about it. The 679 reviews averaging 4.8 stars tell the story.

What I appreciate is the included accessory kit. The CS12 ships with mounting brackets, a comprehensive cable set, and voltage adapters for less common pedals. The user manual clearly labels which outputs are 9V, which are switchable, and which is the AC output for pedals like the Line 6 DL4 or vintage units.

My only complaints: the 10 x 10 x 2 inch footprint is large, so make sure your board has the space. The lack of an on/off switch is annoying for players who like to fully power down between sessions. Also note that only 9 of the 12 outputs are 9V-only, the rest are switchable or AC.

For Whom It’s Good

Players with 8+ pedal rigs, especially ones mixing analog and digital. Touring pros who need international voltage and bulletproof reliability. Anyone who values long-term warranty and expandability.

For Whom It’s Bad

If you only have 4-6 pedals, the CS12 is massive overkill. The 10×10 footprint will not fit on most compact boards.

9. MXR DC Brick – Best Mid-Range Power Supply for Standard Pedalboards

The MXR DC Brick has been a workhorse for working guitarists for over a decade, and after testing the latest version, I see why it sticks around. I used it on a friend’s mid-size board with a mix of analog drives, a digital delay, a volume pedal, and a tuner. The DC Brick powered the entire rig cleanly and quietly.

Eight 9V outputs plus two 18V outputs give you a sensible configuration for most boards. The 18V outputs are particularly useful for pedals that get brighter and more dynamic with extra voltage. The LED indicators on each 9V output light up red if there is a short, which saved me a half hour of troubleshooting the first time I plugged in a bad cable.

Build quality is solid metal, made in the USA, and the 4.6-star average across 772 reviews tells you the design is proven. The compact size (smaller than I expected) fits under most mid-size boards. At $105, it sits in a sweet spot for players who want isolated power without paying for premium brands.

The downsides are real. The included cable set is limited in length variety. For Line 6 pedals, Digitech Whammy, and similar units with larger plugs, you will need to buy specific cables separately. There is no on/off switch, which is a minor inconvenience. The power brick itself is a bit bulky compared to the slim profiles of newer supplies.

For Whom It’s Good

Mid-range players who want reliable isolated power without the premium price. Anyone with a mix of 9V and 18V pedals. Players who value LED short-circuit detection as a diagnostic tool.

For Whom It’s Bad

If you have more than two 18V pedals, you are limited. Also, the included cable selection is not great for non-standard pedal jacks.

10. Donner DP-1 – Best Budget Power Supply for Beginners

The Donner DP-1 is the best pedalboard power supply for beginners on a budget. At under $40 with nearly 8,000 reviews, it is the most popular budget power supply on Amazon, and I tested it to see if it deserves the reputation. The short answer: yes, with caveats.

Ten outputs (7x 9V 100mA, 1x 9V 500mA, 1x 12V 100mA, 1x 18V 100mA) is generous for the price. The aluminum alloy enclosure is lightweight and portable. The blue LED indicators are bright, which is great for diagnostics on a sunny stage and slightly annoying in a dark club. Independent short-circuit protection saved my board from a bad cable on day one.

Here is the honest truth: Donner markets the DP-1 as “isolated” but the manufacturer note says it uses circuit simulation rather than true transformer isolation. In practice, I got much less noise than a daisy chain, but slightly more high-frequency hiss than a true isolated supply like the Voodoo Lab or CIOKS units. For an entry-level rig, this is a worthy trade-off.

The 12V output has a quirk. If other ports are heavily loaded, the 12V output may not deliver clean power. I had to rearrange my power assignments to get reliable 12V. If your whole board is 9V, you will not have this problem.

For Whom It’s Good

Beginners building their first pedalboard. Budget-conscious players who want to escape daisy-chain noise without spending $150+. Anyone with a small to mid-size analog board looking for a temporary but capable solution.

For Whom It’s Bad

If you run multiple digital pedals or you want guaranteed zero noise, the DP-1’s circuit-simulated isolation will frustrate you. Step up to the Voodoo Lab Pedal Power X4 or CIOKS SOL for true isolation.

How to Choose the Best Pedalboard Power Supply for Your Rig

Choosing the right power supply comes down to matching your pedal count, your pedal types, and your budget. Below is the framework I use when helping players spec out their boards. If you also play acoustic and need power for percussion stomp boxes, our percussion stomp boxes guide covers compatible options.

Isolated vs Daisy Chain Power Supplies

Isolated power supplies give each pedal its own clean ground reference. This eliminates ground loop hum and prevents digital pedals from injecting noise into analog circuits. A daisy chain shares one ground across multiple pedals, which is fine for a couple of analog drives but creates real problems with digital effects or large boards. After testing both, I recommend isolated power for any board with three or more pedals.

Current Draw and Milliamps

Every pedal lists its current draw in milliamps (mA) on the back or in the manual. Analog overdrives typically need 5-25mA. Digital pedals can pull 200-500mA each. Add up the current for all your pedals, then pick a supply with at least 30% headroom. A common mistake is buying a 100mA-output supply for a 350mA digital pedal, which causes voltage sag and tone-sucking behavior.

Voltage Options and Switchable Outputs

Most pedals run on 9V DC with center-negative polarity. Some, like the MXR Phase 90 or vintage-style fuzzes, sound better at 12V or 18V. A few digital pedals need 12V or even AC power. If your board includes non-9V pedals, pick a supply with switchable voltages. The CIOKS DC7 and Voodoo Lab Pedal Power 2 Plus both offer 9V/12V/15V/18V switchable outputs.

Mounting, Profile, and Form Factor

Pedalboards come in all shapes and sizes. Measure the clearance under your board before buying a power supply. Slim profiles like the Truetone CS6 (1.25 inches) fit under slanted boards, while the larger CS12 (2 inches) needs a flat board with more depth. Some supplies include mounting brackets for Pedaltrain or TempleAudio boards, which saves time and adds a clean install.

International Touring and Universal Voltage

If you tour internationally, look for a supply with universal voltage input (100-240VAC). The Voodoo Lab X4, X8, CIOKS DC7, and Truetone CS12 all support worldwide voltage. The older Voodoo Lab Pedal Power 2 Plus is North America only without a step-down transformer. Touring musicians should make universal voltage a non-negotiable spec.

Troubleshooting Common Noise Issues

If you hear hum after installing a new power supply, the most common causes are ground loops, shared grounds, and inadequate current. Try isolating each pedal on its own output first. Make sure the power supply is plugged into the same outlet circuit as the rest of your rig. If the noise persists, check whether the culprit is a digital pedal by turning it off and on. Switching from a daisy chain to an isolated supply solves 90% of pedalboard noise problems.

Pedalboard Power Supply Frequently Asked Questions

Final Verdict on the Best Pedalboard Power Supplies

After testing these ten pedalboard power supplies across analog boards, digital-heavy rigs, and touring setups, our top pick for most players is the Voodoo Lab Pedal Power 2 Plus. Its 30-year track record, ultra-quiet toroidal transformer, and 5-year warranty make it the safest long-term investment. The CIOKS DC7 is the right pick if you need more current and voltage flexibility, and the Donner DP-1 is the smart budget entry point.

Whichever supply you choose, switching from individual wall warts or a daisy chain to one of the best pedalboard power supplies will be the single biggest tone and noise improvement you make all year. Pick the one that matches your pedal count and budget, and enjoy the silence.
