Hi @TheBeardBear87, and welcome to the community!
Many who are powering multiple components (pedal board etc.) are using the CIOKS successfully.
For a more robust replacement of the OEM PS, I was recommended the Globtek 12v 3a PS from DigiKey, in the US it was $24 shipped. Maybe DigiKey ships international or there is an equivalent vendor.
One thing to note, the Globtek comes with a set of barrel tips, the QC uses the largest yellow marked tip but if you get this PS, just ensure your polarity is correct (center negative) with a digital multimeter before snapping the tip into place.
I’ve spent quite a lot of time and effort, trying to obtain one of these, took several weeks to arrive and at last when it did, I was surprised it came with a tip adapter to reverse the polarity, because the unit was centre positive. It was not advertised as needing or coming with a tip adapter - does the Myvolts one you have need an adapter or is it centre negative?
Does your 3 pin (Digikey) power supply reduce the interference noise you get with your QC?
I bought one from Amazon, that is a 3 pin IEC supply, the same as your Digikey. I assumed the 3 pin means it’s grounded, and would therefore be quieter, but to be honest it is no less noisy than the OEM supply that came with the QC…
I never had any interference noise and just wanted another more robust PS for travels etc. That being said, there were multiple people who recommended the Globtek (Digi-Key) PS and had great results noise wise so I got it.
I have a Cioks DC7 that I like. I have used that with the 3 summing cables. I have but haven’t tried the new Cioks Crux and ordered a custom summing cable from Omilion audio. I know it seems like a lot but it just depends on the pedal board I use. I want to keep the wiring looking nice. I get that it’s overkill.
It’s worth being mindful with some of the 3rd party power supplies. I tried the Volts and whilst the QC worked, the USB stopped functioning. Went back to the stock power supply and all was good. Switched the Cioks DC7 and everything continues to work as expected, including the USB.
