and now the song come progressively 3 or 2 times in the day (before it was 1 times for the day) im worried about the "electric noise " its coil whine ? and is dangerous or not , even if i hearing this i want just to know if my hx 850 will die or its nothing thks a lot all . ( put volume max for heard the song start 0.25 until the end )

my rig :
z390 gaming plus
9900k
2080ti palit
16gb corsair ddr4
https://vocaroo.com/1ddkRAbMrpn the song , put volume max to 0.25 until end and say me if coil whine or i need to replace this psu thsk all

Song? Sorry, but "new member" and first post, my security sense is kicking in. I am not clicking on that link. Nothing personal.

But, to answer your question, coil whine is just annoying - it is not dangerous. You don't need to replace the PSU just because of coil whine. However, for your sanity, you might want too. The good news is, there's no hurry. You can take the time to research and maybe even wait for a good sale.

Yes, your PSU will die - eventually. But that might be tomorrow, or 6 years from now. No one can say. But I will say it is not coil whine that will kill it.

And for the record, with that hardware, you could easily get by with a quality 650W PSU.

Didnt click the link. But coil whine is normal. Its when the whine starts getting louder and your PC starts shutting off randomly when it becomes a problem. I had a Corsair HX1050 from back in the day that did this and sent it back to Corsair for RMA.

There is no real thing as "electric noise". That is just a general term for all sorts of different noises created by electronics. These can include low frequency hums, to ticking, to high frequency whines, to arcing noises, zaps, sizzles - whatever.

Even if this PSU was sitting on our work benches in front of us, unless we could see sparks coming out of it, there would be no way to conclusively say it is 100% safe.

I would not say whine is "normal" because electronics at these voltage and current levels "should" be totally silent - except for cooling fan noise. But coil (and transformer) whine is quite common. And as I said above, annoying - but not dangerous.

But for sure, if you are worried about it, replace it and save this Corsair for an emergency spare/test PSU. You could also get yourself a decent PSU Tester. This will NOT tell you the PSU is safe. Nor will it conclusively tell you the PSU 100% good. But it will tell you if the output voltages at that load level are within the allowed ±5% tolerance levels. And if they are, that would be a pretty good indication the PSU is working fine.

Is your computer working fine other wise? Or are you having problems with it locking up, shutting down or rebooting unexpectedly?

As for what you can do to prove that link is safe, contribute a 1000 posts and spend a few years here so we can get to know you better. Again, its nothing personal.

Recording method was horrible. It is hard to hear anything past the fan noise and the occasional movement crackle. Even with my PC at 100% volume (through a home stereo and speakers), I could say I hear a bit of a "grinding" noise, but I can't even be sure what it is I am calling grinding either.

As it happens, one of the two machines I refurbed today had an HX-650 in it and the PSU did have coil whine.

All I was doing was replacing fans - but this was a Haswell build so probably a 2014 variant of the Corsiar HX

As I said, "grinding".... Could be a wire was tapping against a fan blade, and inverting it moved the wire away from the fan. Could also be a fan bearing, as orientation would make something like that go away too.

So those PSUs have a clear plastic shroud covering about half of the fan to promote airflow across all of the PSU's heatsinks.

If it's quiet in a fan-up orientation with the plastic shroud hanging down from the fan blades, it's possible this has just warped a bit in the heat and is catching the blades slightly.

Not sure on your version but those plastic shrouds can melt and drop in PSUs with a semi-passive operation

If you're going to open your PSU up to check, be very careful. You can get a nasty shock from PSU capacitors!

You can rule out the fan for definite by stopping it. I mean your finger won't fit through the grille but something like a credit card will jam the fan blades for long enough to work out if it's the fan making the noise or not.

Coil whine sure is irritating but it's not really bad for the PSU.

soooo thks a lot bro ! thats it
i launched occt test , the fan started to spinning and after 2-3 min the noise started ! quickly i blocked the fan and suspense ..... the noise disappear !
so for sur i deblock the fan , wait 1 min and the noise restarted so im happy that its just the fan and not a component from my psu
so i change it or just replace it ? or maybe nothing the noise im not worried now i know its fan what do you think ?

You can probably send it back under warranty if it's bothering you; I don't think a PSU fan should be audible under normal load. There are two ways a fan could be making noise, and I can't really tell from your description or recording which one it is:
  1. worn bearings (which means the fan must be replaced)
  2. something else being caught by the fan blades as they spin (cable or that plastic air guide)
If you're not willing to send it off for RMA you could open it up to try and work out what's getting in the way of the fan. Replacing a PSU fan is more complicated because they're usually soldered on rather than using a convenient 3-pin header.

If you don't understand which parts in a PSU hold charge (even when it's unplugged) then I wouldn't recommend opening your PSU at all. The electric shocks you can get from the capacitors are genuinely dangerous.

This is not the best thinking if you are afraid staying with out computer.
The PSU can go bad even from mains power line incident, instant over-voltage due bad weather.
Such accidents are not covered by warranty.
Best approach this is having and a spare PSU among with protection due uninterruptible power supply.

No. At least not immediately. The problem is there is no way of knowing when or if problems will arise. It could last days or many years! However ALL motors eventually fail - if kept in service long enough.

But fan noise (assuming the blades are not hitting anything) typically indicate flawed and/or worn bearings. Flawed bearings wear faster and worn bearings will keep wearing. Eventually, one of 3 things will happen. (1) The fan motor will fly apart (very rare). (2) The bearings will start to seize and the fan will slow down or even stop causing the PSU to overheat and [hopefully] shutdown to protect itself. Or (3), you will get so fed up with the fan noise, you will replace the PSU and just keep the noisy one for a test/spare PSU. I recommend #3 - before #1 or #2 occur.

okk thks , for this moment i limited the power limit of my gpu and now my psu fan not spinning because she is less used so no noise ... but thks for advise i will see after summer maybe the temp , if always noise i change it . i think its not the blade hitting something because the noise comes after 2-3 min that the fan spinning so he is silent for 2-3 min , if it was blade hit the noise start when the fan spinning ad not after 2-3 min youre right for the "2" its bearing i think
