PC PSU making really faint buzzing noise

[Confused Idiot]

Idk if it is coil whine but I have to put my ear less than 6 inches away to hear it, this is the only problem and I just started hearing this today...


Is this dangerous? I'm really scared!

It's a EVGA SUPERNOVA B2 750 Watt PSU

It's probably a psu coil whine, look some up on youtube and see if it makes a similar sound. Don't worry it won't blow up or anything it a common with psu's and gpus

Did it just start happening? Most likely nothing to worry about - could be coil whine. Could be a capacitor going bad. Nothing you can really do with it though. Could also be an issue with the psu fan - like a bearing going bad.

It's not a whine, it's a buzzing noise.

If its most definitely a buzz then I'd look at the PSU fan.

Is it like this?
