Hiss sound with mic

Hello all. I hope you are all doing well. I have a question which pertains to screen capture and more so mic input levels and 'hiss' sounds. I have NI komplete audio 6 interface connected via USB to my pc. I have a Rode pod mic connected to the front of my interface into input 1 via XLR (good quality cable). I am wanting to record screen capture. When I increase the input gain to 100 percent (I have to because the voice coming through the mic is very low) I get allot of 'hiss' sounds or white noise as they say. I have everything disconnected from the pc that is not needed , monitors are turned off, pc power plug is on its own plug. I feel in Cubase 13 pro I have to increase the mic volume to full to get a decent level , but again when its at this level I still get white noise and 'hiss' . The only way I can remove it is by adding a plugin in the channel but I want to know if theres something else thats wrong . Is it my interface ? not enough pre-amp power to boost signal to cubase or what ?
