PSU Buzz

[Beigels]

I built a gaming PC about a month ago, and ever since then there has been this slight buzz which seems to be coming from my PSU. When doing more rigorous activities, like playing newer games on high graphics settings, the buzz/grind noise becomes much louder. I have no idea what the issue is. I have heard I need to replace it, or my screws on my case are wiggly. Is this a problem I should immediately fix or if I leave it for now, like I have been doing, will it go away? Should I be worried about it? Please help.

What type of PSU do you have? Manufacturer/model/wattage?

the buzz is most likely from a capacitor in the psu when it is being highly used just be sure you are not pulling more watts from the psu then it can handle and you will be fine

Are you sure it's coming from your PSU and not your GPU? What you're describing sounds a lot like coil whine, which is typically from the graphics card.

 

If you're still within the return/exchange period on the PSU, I'd do so and see if that fixes it.
