Mic phantom power noise

Recommended Posts

Posted · Original PosterOP

So, when i'm using my microphone it needs phantom power from USB and when i use USB ports on my motherboard my mic recording have loud noise and when i use power bank as a phantom power the sound is crystal clear. I've heard that you need to ground pc to fix that so is that what i need to do or there is other fix?

My mic is have a 3.5mm jack for sound and usb for power.

P.s. i cant always use power bank because mic take so little power that power bank goes to sleep in 3 min.

Motherboard: Z370 AORUS ULTRA GAMING 2.0 OP

PSU: EVGA 500 UK Plug

if it is still under warranty, RMA it and tell them you had this problem twice now.
