I’m using the “Ritter QC Amp Base SHP” with power option for QC. Sure, it’s much more than just “power supply”, it’s a power amp solution nicely setup especially for QC. I like it… power, power, power, power in several meanings 
I’ve been using 12V3A power adaptor that is mainly for laptop computers.
These days, I and my friends started using USB PD(type C) 12V decoy cable + mobile battery or PD charger.
Notes
Decoy cable has positive center plug, you have to switch the polarity somehow.
Also, 12V is not officially supported on PD standards, some chargers like Anker products do not output 12V. You have to read the product notifications carefully before you buy.
Sweetfootpedals.com makes custom PS including the QC. I have been using mine every day with no noise or issues.
Walrus Canvas HP is working great for me - basically like a 3 tap isolated power supply with a 4th that’s a built-in Cioks Crux. Also has 24v thru to add-on another Walrus / Mono / Strymon brick for expansion if needed.

I think I may order one and check it out. I like the design.
Hi,
so I’m new here, the QC is on it’s way to me and I’m already thinking about how to built a pedalboard. Has anyone tried the Spaceship Pedalboards (Harley Benton)? Buy favourably priced Pedalboards online at Thomann – Thomann United States
I’m not that sure about how to calculate the power so any help is appreciated. I’m planning to use the QC and maybe 1-2 extra pedals.
I ended up getting this power supply with a reverse polarity connector, and it seems to work really well. I got flashing blue lights on the footswitch lights when I powered it up - is that typically what happens when you power on the QC? I never checked before, just want to make sure it’s not some kind of warning/error sign.
Seems legit. Just restarted the QC next to me and behaved that way
Yes, the QC always starts up that way.
I now made my own power supply to use with my pedal board. I use a 24V-3A-Power-Supply and have a 5A-capable step-down converter for the QC. Thrown in a couple of smaller step-down-converters (5 pcs for 10€) to have power for other devices on the board. All outputs are adjustable…
the package gets only handwarm with no hum and noise, the most expensive was the hammond case.
