windows 10 pc?

Yes

Windows 10 made some changes to the mic audio path.
Have your tried the basics?

Is it the Neewer NW-100 phantom power unit? If so, check that you are feeding it with a mains transformer that delivers 18V AC. It's the AC that is the important bit.

Mine doesn't output that so i think this will be the problem. Mine says DC 13.8V 8W. I found one on amazon that says 18V2A. Should that be good? Thanks btw

I can only speak for the NW-100 model, as that is the one I have. That model needs 18V AC, since it uses a simple voltage-tripler rectifier to produce 48V DC.

The 18V AC mains adaptor that mine came with is made by Yee-Hu, an unknown name from the Wild East.

Are you able to try it with a mixer or interface to see if it is indeed an external phantom supply problem?

If his Neewer PP supply really is the NW-100 model, or is any other type that uses the voltage-multiplier method of generating the PP voltage, there is no point in doing further investigations until the mains power unit is changed to one that delivers 18VAC.

Got the 18v AC today and that was the problem! Thank you so much!

That's good!

I hope you connected the output from the power supply the right way round.

How do you connect AC "the right way around"?

Or did I miss the joke somehow? :D

Maybe.
