No, the power supply is very old, take a pure power 11 or straight power
I can only tell you something about the miko. It's a condenser studio USB microphone. USB means that you can regulate it very badly. Condenser studio means that you should be very quiet and your walls should reflect little. The microphone really records EVERYTHING that happens in the room. The bracket is generally described as impractical. So you better get a microphone boom right away. The Tonor T20 would be recommended.
I personally (medium voice) use the Rode M2. This is a condenser stage microphone and with a good setting and close (20 cm) meeting hardly picks up ambient noise. https://www.thomann.de/...ode_m2.htm
Depending on your voice (low?) You should also take a look at the Sennheiser 835s
Then you still need a USB audio interface. I'm happy to recommend a Steinberg your 12 or Ur22. You can supply it externally when the USB messes around again.
