Each and every component generates its own noise. Never fear, the whole system is immersed in a sea of noise. The little bit generated by components is definitely worth considering but frankly the least of your problems. That is a main reason why power cords work in the first place.
Therefore, it is pointless to waste time trying to figure out what noise is coming from where. Forget all that, just deal with the fact noise is everywhere.
Would you hire an electrician to operate a screwdriver? Can you operate a screwdriver? No? If no then you can pay me $100 and I will show you how. Then once you know which end goes in the slot and which direction to turn the screws you go to the breaker panel flip the power off and swap your outlet. Take you about 5 minutes.
