Psu making funny noises under load

Hello everyone,
Recently my PSU has started making noticable electrical noises under load
(similar to the noise of plugging in a speaker, or turning on an old TV, if that helps)
I was wondering if that's OK.
I did overclock recently so it could be it's just trying to keep up.
Note this is not a high pitched noise and the fan works fine.
Also I didn't experience any strange restarts or crashes.
Thank you in advance.

If you say which model it is and what it is powering and how old it is we can have a guess at its condition.

Of course, my bad.
The PSU is a Seasonic 550w, bronze rated (don't know the precise model)
CPU is a core i5 -4670k (peak power ~ 95w)
GPU is an MSI GTX 760 (also overclocked).
PSU's about 1 year old

Just that the works fine doesn't mean there's nothing wrong with the bearing.Are you sure the sound doesn't come from the fan?

Pretty sure. The sound is a buzzing/ distortion and when approaching then fan it didn't seem louder.

Overclocking changes the max TDP - that is why only some motherboards are capable of overclocking. Turn changing everything back to original speed and see if the problem persists if it does, RMA the power supply.

I'm not at home so I'll check later, but either way should I be concerned?
other than the noise everything functions OK

If it's just an extra noise output and the voltages are okay will you be fine.Just keep an eye on the voltages.
You could us the next for that,
hwinfo32
open it,mark sensors=V and click run.

You could of course also rma and see what they ave to say about it.That's up to you.

I'm not sure what you mean by OK voltages.
I did monitor everything and the values are fine on both compoments (I overclocked both CPU and GPU).
I also monitor it on screen and while benchmarking, so voltages are just as neccesary.
So to clear things up, as long as nothing unusual happens I'm OK?

I'd rather not RMA it unless I have to as it means I'll go at least 2 weeks without the PSU while it's being inspected.
and thank you all for the quick responses, by the way.

PSU: Seasonic 550W Bronze PSU (Eco series, I think)
Motherboard: ASUS ROG Gene VI
CPU: Core i5 -4670k @4.3 ghz (fairly low voltages)
GPU: MSI TwinFrozr GTX 760 (overclocked and overvoltaged)

You really shouldn't overclock with that power supply.

Hi,
I'm sorry for my mistake but it turns out the noise is coming from the GPU fan, not the PSU.
I assumed it was the psu becasue the noise sounded electric.
Thank you all and sorry.

If it's a SEASONIC ECO it's not Haswell compatible.

I had it before moving to haswell.
Everything's working great for about 6 months now, even when over clocked, so it seems fine.

I think you're fine too with 550watt,even overclocked.

You can look in the next link for the range where the voltages should be within,

I checked and I am indeed within range.
Thank you ! I was wondering if I haven't set anything wrong.

If that's about overclocking only prime and/or occt,even linX can give that answer.

My MSI 260x OC 2 GB is crazily noisy as well but it stays around 40º to 45ºC while gaming. It makes a really loud stopping/braking sound when I shut down from starting from day 1.

I swapped out the PSU since I was worried about the noise but it still persists. It kind of sounds like 'guruguruguruguruguruguruguruguruguruguruguruguruguru' really really fast.

@vic 40
I used prime 95 and Realbench for the CPU, and Furmark for the GPU. Everything ran OK so I guess I can relax.
@Pondering
My case is different. The GPU ran fine for the last year (though I never ran at full fans before) .
The sound mine makes is a static buzz like noise (like astronauts and military radios in the movies, if that helps)
Strange enough...
Temps are same as always, though, and nothing is loose...
