Quick answer The CIOKS DC7 Power Supply scores 9.6/10 with us. Amazon owners rate it 4.8 out of 5 across 320 reviews, above the 4.6 average of the 11 power strips we track. It was listed at $289.00 on Amazon when we last checked in September 2026.

The highly anticipated and long-awaited CIOKS DC7 is the thinnest, most flexible and most unique power supply for powering effect pedals from the Danish power supply specialists CIOKS. The groundbreaking DC7 has a one-inch (25,4mm) profile and weighs 1.1 pound (500 grams) thanks to the pure 2-stage switch-mode technology inside. The profile may be low but the power ratings are certainly not – the DC7 puts out a maximum of 48W from its 9 outlets and allows the user to connect multiple high-current effects such as devices from Effectrode and Eventide without noise of any kind.

CIOKS DC7 features 7 isolated DC-outlets for effect pedals each with four selectable voltages. Each of the outlets can put out 6W which corresponds to 660mA of current at 9V. Additionally the DC7 has also a 5V USB outlet and an auxiliary 24V outlet.

The DC7 is expandable with CIOKS 4* and CIOKS 8* as well as with oth

    Small and powerful powerful power supply

    I wanted a smaller, more powerful power supply with more options and no noise for my pedalboard. This Cioks power supply fits that description perfectly. Loads of power with variable power options. Came with all the cords needed to get everything hooked up and powered on. Super quiet, totally isolated and the power is stable.If you're in need of a powerful, durable, safe and quiet power supply... get a Cioks... you won't be disappointed.

    Works as advertised. Quiet!

    I am very happy with this pedalboard power supply. I combined it with a Cioks DC-4, for a total of 11 individually powered pedals. First: it is quiet! I've tried cheaper power supplies, but those never worked for me. This one is expensive, but worth every penny. Comes with every cable you could need and then some. A good selection of short, medium and long cable lengths makes keeping things tidy below the board easy. I just used the standard "Boss-style" center negative cables, but they also include specialty cables for your positive polarity pedals (Line-6, Eventide, etc.). Very pleased. You

    The best source in the market

    Easy to set up (just connect it).It's thin!, so it fits comfortably in any pedalboard, and the needed screws are supplied.Solved my signal AC noise issues.Powerful enough to connect my Quad Cortex using the Crux adaptor.

    Uses RCA phono plugs

    KNOW THIS: This unit has jacks for *RCA phono plugs*, not 2.1mm barrel-style plugs like other power supplies such as Voodoo Labs. This is important if you already have a variety of barrel plugs to work with your stuff, including current doublers and voltage doublers and 2.5mm plugs: you can't use them with this. It's not immediately evident or called out that I can see. Yes, once you know, you can plainly see the phono jacks in the pictures -- but if you haven't used phono plugs in years, or never have, you won't recognize them.That said, great unit! Plenty of power in a small size, with no bu

    Fixed one of my pedals!

    I originally was using a Donner power supply, but one day my BOSS pedal that was plugged into it. Stopped working? I couldn’t figure out what happened? I tried to fix the pedal, but no matter what I did, it just wouldn’t work anymore. After doing research. I found out the Donner power supply does not offer isolated power. It’s basically a daisy chain, so I figured somehow the power supply fried my pedal. I didn’t want to risk damage to any other pedal, that’s when I researched other better pedal power supplies. After a lot of research I went with the Cioks. Just for a laugh I decided to plug m

    This thing is awesome.

    I picked this up to power a bunch of synths and FX for a portable synth rig. Easily powers a wide array of devices, and I was even able to power a few low-power USB devices from the USB port (via hub). Only downside is that I had to special order a couple cables because the included cables were right angle and I didn't have enough clearance to use them for two of the devices that I've got. While this is a bummer, I wouldn't knock them for it, as I'm sure I'm a little outside the typical use case here.

    It’s one of the best power supplies out there.

    I play guitar and the cheap power supplies add so much noise from not being properly isolated that it was causing issues.When you put an Overdrive Pedal in your chain, it’ll exacerbate any noise introduced by a cheap power supply.Buying this one fixed a lot of sound problems from cheap equipment and it’ll power almost anything.
