Guitar Effect Power Supplies by the numbers
Measured across all 85 models we track, not a sample.
Median $20 — half of all guitar effect power supplies here cost less.
How to choose the best guitar effect power supplies
Current Output
Enough amperage is key. Don't skimp; your boutique overdrive will thank you. Underpowered supplies lead to dropout and weird, unpredictable behavior - a muddy low-end or flubbed articulation is a dead giveaway.
Noise/Hum
This is the big one. A noisy power supply will muddy your tone and make your signal-to-noise ratio atrocious. We're listening for any audible hiss or hum, especially when pushing your pedals hard.
Isolation
Good isolation prevents one pedal from bleeding noise into another. That means your reverb shouldn't be picking up the fuzz's oscillation. This is where cheaper units often fall short.
Voltage Regulation
Consistent voltage is vital for pedal stability. Fluctuations can cause erratic behavior and shorten the lifespan of your effects. It's subtle, but noticeable in dynamic playing.
Physical Build/Reliability
Let's be honest, these are budget units. We're looking for something that won't fall apart after a few gigs, even if it's not built like a tank.
Buying guide
Alright, so you're building a pedalboard, or maybe just want to stop daisy-chaining and risking noise issues? A dedicated power supply is the smart move, but let's be real - $50 isn't a ton to spend. We're looking for bang-for-the-buck here, something that'll keep your pedals running reliably without breaking the bank and introducing more hum than your vintage tube amp. This list is for those of us who want solid performance without emptying our pockets.
At this price point, expect some compromises. You probably won't get a ton of isolated outputs, and the power regulation might not be as rock-solid as a Strymon or Voodoo Lab unit. Look for a decent current rating per output (at least 300mA is a good starting point), and pay close attention to reviews regarding noise.
Don't expect premium connectors or a super-sleek enclosure - it's about function over form.

Questions
Will a $50 power supply work with my high-end fuzz?
It might. Depends on the fuzz's current draw. Check the fuzz's specs and make sure the power supply can handle it. If it drops out or sounds weak, you'll know it's not enough power.
What's the deal with isolated outputs?
Isolation means each output is electrically separate. This minimizes noise bleed between pedals. Budget units often share grounds, which can introduce noise. It's a trade-off.
Can I daisy-chain pedals from this power supply?
Generally, no. That defeats the purpose of having a dedicated power supply. Daisy-chaining introduces noise and voltage drops. It's a bad idea.
My pedals are all 9V - does that mean any power supply will work?
Not quite. Voltage regulation and current output are just as important as voltage. A cheap, underpowered 9V supply can cause all sorts of issues.
How do I know if my power supply is causing noise?
Start by isolating pedals. Power them directly from the supply, one at a time. If the noise disappears, the power supply is likely the culprit. Also, check your ground connections.
