Connect Rode nt a 1 with phantom power and aux?

I bought the Rode nta1 and a phantom power supply and now wanted to connect it to my laptop from the phantom power supply with a jack to aux cable and now I wanted to ask if this is possible at all.

For sure. You go into the micro 3.5 jack input of your computer. Of course it won't sound that great. The sound chips in the computer are grotto bad in 99.9% of the cases. Of course you can drive a racing car (your nice microphone) with the engine of a small car. (the phantom supply with the built-in sound chip) is not fun. You bought an expensive microphone. There should be an interface in there. The cheapest would be a behringer ur12 around 40 euro. You still have some residual noise. Better a Steinberg your 12 or Ur22 from 90 euro or, if your computer has a strong USB, a FocusriteScarlet, also around 90 euro
