The CIOKS DC7 is one of those pieces of gear that does not look very exciting at first.
It is not an overdrive pedal. It is not a delay pedal. It does not make huge ambient washes, brutal distortion tones or weird modulation sounds. It just sits under your pedalboard and powers the things that actually make noise.
And yet, if you have ever built a pedalboard with more than a couple of pedals, you already know how important that little boring box can be.
A bad power supply can make a pedalboard noisy, unreliable and annoying to use. A good power supply disappears. You plug everything in, the pedals turn on, nothing hums, nothing complains, and you can stop thinking about power completely.
That is basically what I want from a pedalboard power supply.
And after using different CIOKS power supplies for years, the CIOKS DC7 immediately felt like the kind of thing I had been waiting for.
My History With CIOKS Power Supplies
Before getting into the DC-7 itself, I should probably mention that I have been using CIOKS power supplies for a very long time.
I think I built my first proper pedalboard somewhere around 2009 or 2010. Since then, I have gone through more pedals, pedalboards, amps and general guitar-related nonsense than I probably want to admit. If you have seen my gear history videos, you may already know that I used to trade gear a lot.
A lot a lot.
Pedals were no exception.
Because of that, my power supply needs kept changing. Sometimes I needed something small. Sometimes I needed more outputs. Sometimes I needed different voltages. Sometimes I downsized everything, only to build something bigger again a few months later, because apparently that is just what guitar players do.
Most of the time, I ended up using CIOKS power supplies.
I had the Adam Link. I think I had that one twice. I also had the Schizophrenic, and I am pretty sure there were a few others along the way. The main reasons were always the same: build quality, useful outputs and sizes that actually made sense for real pedalboards.
There was a time when CIOKS had one of the only power supplies I could fit underneath a Pedaltrain Nano. That mattered to me, because I like small, practical boards. I do not want the power supply to decide what pedalboard I can use.
So when I got an email asking if I wanted to check out the CIOKS DC7, it took me about 0.1 seconds to say yes.
What Is the CIOKS DC-7?
The CIOKS DC7 is a slim, high-powered, expandable pedalboard power supply with seven isolated outputs.
Each output can be set to 9V, 12V, 15V or 18V. That alone makes it very flexible. Instead of having one or two special outputs and then a bunch of basic 9V ones, the DC7 gives you the same voltage options across all seven main outputs.
That is the part that immediately makes this interesting.
At 9V, each output can provide 660mA. That means the DC7 can handle a lot of modern digital pedals that may be too hungry for older or smaller power supplies. It is not only for simple analog drives and fuzz pedals. It can deal with bigger delays, preamps, cab simulators and more complicated pedalboard setups.
On top of the seven isolated pedal outputs, the DC7 also has a USB output and a 24V auxiliary output. The USB output is useful for powering or charging things like a phone or tablet on a pedalboard. The 24V output can be used for expanding the system with other compatible CIOKS units.
So this is not just a power supply for one fixed board.
It is more like the foundation for a pedalboard power system that can grow with your setup.
The Slim Design Is a Big Deal
One of the most impressive things about the CIOKS DC7 is how slim it is.
Power supplies are often awkward. They might have enough outputs, but they are too tall to fit under your board. Or they might fit, but they do not have enough current. Or they might be powerful, but they are the size of a small brick.
The DC7 feels like CIOKS looked at all of that and decided to solve as many problems as possible at once.
It is thin enough to make pedalboard mounting much easier. Compared to my previous Truetone 1 Spot Pro, the DC7 feels almost ridiculously slim. The 1 Spot Pro is a good power supply, and I used it because it is powerful and practical. But it is also quite large, and fitting it under certain pedalboards can be a pain.
The DC7 is much easier to imagine under a modern low-profile pedalboard.
That matters because a pedalboard should be easy to move, easy to set up and easy to use. If your power supply makes the board bulky or awkward, it affects the whole rig.
A slim power supply is not just about looks. It changes how easy the board is to build.
Seven Outputs That Actually Feel Useful
The CIOKS DC7 has seven isolated outputs, and the important part is that all seven are genuinely useful.
With some power supplies, you technically get several outputs, but only a few of them are powerful enough for modern pedals. You end up having to plan your whole board around which output can power which pedal.
That can get annoying very quickly.
With the DC7, each main output can do 660mA at 9V, and each output can be switched between 9V, 12V, 15V and 18V. That means you are not constantly trying to remember which output is the “good one.”
They are all the good ones.
That makes building a board much less stressful. If you have a high-current delay, a preamp, a cab simulator or something that wants 12V, you have options. You are not stuck with one special output that needs to handle everything.
This is the kind of feature that sounds boring until you actually build a board.
Then it becomes very exciting.
The Voltage Options Make It Flexible
The voltage switching is one of the biggest reasons the CIOKS DC7 feels so versatile.
You can set each output to 9V, 12V, 15V or 18V. That covers a lot of pedal situations. Many pedals use standard 9V, but some preamps, drives, delays and utility pedals can run at higher voltages. Some need 12V. Some can run at 18V for more headroom.
Having those choices on every output gives you a lot of freedom.
For example, in the video I used a few pedals to show why this matters. A Boss DD-500 can need quite a lot of current. A Two Notes Cab M runs at 12V. A Two Notes Le Clean needs 12V and 500mA, which is exactly the kind of thing that can cause problems with many pedalboard power supplies.
The DC7 can handle those kinds of pedals.
That is a big deal if you are building a more serious pedalboard rig. You might have digital delays, preamps, IR loaders, MIDI pedals, switchers or other high-current devices. You do not want to use five different wall warts just to make the board work.
The whole point of a pedalboard is that it should be practical.
The DC7 helps with that.
The Power Indicators Are Actually Useful
Another thing I really like is the way the DC7 tells you what is happening.
Each output has its own indicator. If you overload an output, the light can dim or go out, so you can see that something is wrong. That is very useful when troubleshooting a complicated pedalboard.
There is also a total load indicator. It tells you how much of the total capacity you are using, so you can see whether the whole unit is getting close to its limit.
This is one of those features that feels very practical.
Instead of guessing whether a pedal is underpowered, you can actually see what is happening. If you are building a board with several high-current pedals, that can save you a lot of time.
Power problems can be frustrating because they do not always look like power problems. Sometimes a pedal behaves strangely. Sometimes there is noise. Sometimes something randomly shuts down. Sometimes you start blaming the pedal when the real issue is the power supply.
The DC7 gives you better information.
I appreciate that.
USB Power Is a Nice Bonus
The USB output is also very useful.
A lot of modern pedalboards are not just pedals anymore. You might have a phone, tablet, MIDI controller, Bluetooth page turner, tuner app, setlist app or some other device involved in your live or practice setup.
Having USB power directly on the power supply makes sense.
It means you can charge or power something without adding another charger to your rig. That is especially handy if you use a tablet for charts, lyrics or setlists.
Again, this is not the most glamorous feature in the world.
But on a real pedalboard, practical features matter.
Expandability Makes It Future-Proof
The 24V auxiliary output lets you expand the DC7 with compatible CIOKS units.
That means you can start with the DC7 and add more isolated outputs later if your board grows. You still keep the setup clean, and you can power the extended system from one mains cable.
That is a very smart idea.
Pedalboards change. Mine certainly have. You might start with a small board, then add a bigger delay, a preamp, a switcher, a modeler or some utility pedals. Suddenly seven outputs might not be enough anymore.
With the DC7, you are not completely stuck.
You can expand the system instead of replacing the whole power supply. That makes it feel more future-proof than a fixed power supply with no expansion options.
And knowing guitar players, future-proofing is not a bad idea.
How It Compares to My Previous Power Supply
Before the DC7, I had been using a Truetone 1 Spot Pro.
That is a good power supply. I do not want to make it sound like it was bad. It had useful outputs, enough power for many setups and a dedicated 18V output. It did the job.
The problem was the size.
It is big. On some pedalboards, fitting it underneath was not fun. I had a two-step pedalboard where I liked the board itself, but getting the power supply mounted neatly was a real issue.
That is where the DC7 immediately feels better.
It gives me the power and flexibility I need, but in a much slimmer package. It feels like a more modern solution for the way pedalboards are built now.
The 1 Spot Pro is still a solid product. But the DC7 feels easier to fit into different board designs, especially if you want a clean and compact setup.
Can It Power Big Digital Pedals?
This is probably one of the main questions people will have.
The short answer is: it can power a lot of demanding pedals, but you still need to check the requirements of each device.
The CIOKS DC7 can provide a lot of current per output, especially at 9V. That makes it suitable for many modern digital pedals, delays, reverbs, preamps and cab simulators.
For something like a Line 6 HX Stomp, you may need a special cable or use more than one output. I would not just plug things in randomly and hope for the best. With expensive digital pedals, always check the voltage, polarity and current requirements first.
Still, the fact that the DC7 can even be part of that conversation is impressive.
Many power supplies are fine for traditional pedalboards but start to struggle when you add modern high-current devices. The DC7 feels much more prepared for that reality.
Build Quality
The CIOKS DC7 feels very well built.
That has been my experience with CIOKS power supplies in general. They tend to feel sturdy and reliable. I have not had problems with the power supplies themselves over the years. The reason I kept changing them was not because they failed. It was because my pedalboards kept changing.
The DC7 continues that tradition.
It is lightweight, but it does not feel cheap. It feels like something that can live under a pedalboard and handle real use.
That matters because power supplies are not something you want to baby. They live under boards, get moved around, get connected and disconnected, and generally deal with the less glamorous side of gear life.
The DC7 feels ready for that.
Is the CIOKS DC7 Expensive?
The CIOKS DC7 is not a cheap power supply.
That is important to say clearly. You can absolutely buy cheaper power supplies. You can also build a small pedalboard with a simpler unit and be perfectly happy.
But the DC7 is not really aimed at the most basic setup.
It makes the most sense if you have a serious pedalboard, power-hungry pedals, different voltage needs or a setup that may grow over time. In that context, the price starts to make more sense.
A good power supply is not the most exciting gear purchase, but it can protect the rest of your investment. If your board has expensive delays, preamps, modelers, reverbs and drives, powering them properly is not optional.
It is part of the rig.
So yes, the DC7 costs more than a basic power supply. But it also solves problems that cheaper units may not solve.
Who Is the CIOKS DC7 For?
The CIOKS DC7 is for players who want a serious, compact and flexible pedalboard power supply.
It makes sense if you use several pedals, especially if some of them need more current or different voltages. It also makes sense if you want to build a clean pedalboard that can be powered from one mains cable.
It is also a great option if you change your pedalboard often.
That is probably why I like it so much. I have rebuilt pedalboards many times, and the DC7 feels like a power supply that can keep up with those changes. Instead of constantly wondering whether your power supply has the right output for the next pedal, you have much more room to move.
If you only have two or three basic pedals, the DC7 might be more than you need.
But if you are building a board that includes modern digital pedals, preamps, cab simulators, delays, reverbs or MIDI-related gear, the DC7 makes a lot of sense.
CIOKS DC7 Review: Is It Worth It?
Yes, I think the CIOKS DC7 is worth it if you need a high-quality pedalboard power supply that can handle modern pedals.
It is slim, powerful, flexible and expandable. The seven isolated outputs are genuinely useful, the selectable voltages make it easy to work with different pedals, the USB output is handy, and the power indicators make troubleshooting easier.
It also feels like a product designed by people who understand pedalboards.
That is probably the biggest compliment I can give it.
It does not feel like a generic box with outputs on it. It feels like something made for real-world pedalboard problems: tight spaces, power-hungry pedals, mixed voltages, expandability and clean setup.
For me, that makes the DC7 one of the most impressive power supplies I have used.
Final Thoughts
The CIOKS DC7 is not exciting in the way a new overdrive or delay pedal is exciting.
But it is exciting in the way a properly working pedalboard is exciting.
It gives you seven isolated outputs, plenty of current, selectable voltages, USB power, expandability and a slim design that makes it much easier to fit under modern pedalboards. It feels sturdy, practical and very well thought out.
If you are building a serious pedalboard and want one power supply that can handle a lot of different situations, the DC7 is very easy to recommend.
It might be more than you need for a tiny beginner board. But if your pedalboard has started to become a real rig, this is exactly the kind of thing that makes life easier.
And sometimes, making the boring part of your rig disappear is one of the best upgrades you can make.
