Condenser mic not detected by PC

I have a Neewer nw-700 condenser mic, Neewer 48v phantom power supply, a xlr to xlr cable and an xlr to 3.5mm cable. When I put these together (Mic to phantom power via xlr-xlr then phantom power to pc via xlr-3.5mm) I can't find the device. It isn't recognised by my Windows 10 system. It is also not detected by my MacOS High Sierra laptop.

On my pc I have Realtek audio drivers and the Realtek audio interface software. It is all up to date, and I have uninstalled them and reinstalled them. I have tried both the front and rear ports on my pc. I have them in the right ports, but I tested others just in case. I don't have a USB adaptor, but I am considering buying one, I am also considering buying an xlr-usb cable. From all the videos I have seen, my setup should work. So I don't know why it isn't. Should I buy an adaptor, or a cable, or is my device faulty. If buying a device is the way to go, which ones are known to work with my device?
Thanks for any and all help!


(Answer) For anyone interested, here is my best explanation of how I fixed my issue: I removed the power supply. The microphone I am using has no need for a power supply in a desktop PC with sufficient power pack. The only reason I ever thought it was damaged or broken or not working, was because this device wasn't picking up sound. As it turns out, and I am stupid for not knowing this, this particular condenser mic doesn't receive any sound on one side, only the other. I needed to turn it around, but the logo on the mic wasn't facing me, so I always oriented it that way. Ok, now down to the explanation of power supplies and stuff.

- A condenser mic only needs a power supply if it cannot receive its power from its input source. My PC has a power pack which produces enough power for the device to receive some. I also have it connected though an XLR to 3.5mm jack. This cable is essential to use the device, and transmit phantom power. If you are using a laptop, an audio interface or a power supply is required because the laptops battery doesn't produce enough power. A sound card isn't required to make the mic work, only to make it sound better. It can transmit the audio in a format which is more readable and can do it faster than a 3.5mm jack can, thereby meaning a sound card is just taking the same signal and enhancing the strength of it. That might all be wrong, but that is my understanding of sound cards. They clean up some of the sound. However, they are not essential in the setup.

Thanks for the 0 replies, means everyone knew I was an idiot and let me figure it out for myself. My mic sounds pretty good, for a $40 mic.
