Higher efficiency PSUs are more prone to buzz or hum due to their increased sensitivity to the input voltage from your wall outlet. If the buzz is barely audible, then you should not have any problems. You do have a 5 year warranty on the TX650, so at any time that the noise gets louder or you begin to have any stability issues which could be related to the PSU, we can definitely replace it for you.
