Received my 3080 today, now my PSU is producing coil whine :(

Guessing the PSU is running at a higher load, putting more stress on the capacitors etc.

Test with a different PSU if you can?
 
It's quite common for coils to whine when there is significant load on them. This is simply as the current increases so does the magnetic field they produce. The stronger the field the more force on the coils, so they can physically move - vibrate. One of those neighborhood transformers would make a pretty deafening noise if they were not subdued by being immersed in oil. In your PSU coils are usually covered in something to help reduce the vibration but the older the PSU the more the coils have managed to work themselves loose. Whether you can get it replaced is up to the manufacturer.
 
The EVGA G3 750W PSU should be more than capable of running a 3080 especially with using individual cables per connection like you said you are. You could check the manual to see if you're using the right VGA ports on the PSU as I know the G3 has quite a few of them. Also some tracking in GPU-Z or similar showing power usage compared to what noise level you're getting might help troubleshoot further.

Is your PC connected to an extension/PSP with multiple other devices plugged in? I don't know if that'd make a difference but I wouldn't rule it out. Your system will in general be using more power now than it was previously so your PSU might always have had this fault and it was just never apparent because yours system didn't need the power.
 
I have a friend nearby who needs me to build his pc into a new case he purchased, I told him I’d do it for him next week or maybe the week after depending what time I have. But I remembered he has a HX850 so yeah.. told him I’ll build it for him a lot sooner provided I can test my 3080 in his system. I’ll find the time somewhere :p

Um, what?
 
From what I can tell in the frantic research I’ve been doing about coil whine in the past 5 hours, is my PSU is definitely capable of running my 3080, coil whine doesn’t exactly mean my PSU is struggling, it’s just a response to the higher current flowing through it. Maybe I got a bit unlucky as like with all computer hardware, every component is different, even if it’s the same.

Trying to RMA this PSU will probably not be successful also as apparently companies don’t really RMA because of coil whine, unless in very extreme cases which I wouldn’t call mine extreme.

I could super glue the coils but.. no, I’m not even venturing down that path lol

I’ll test it in my friends rig just to 100% confirm it isn’t the gpu then I guess I’ll just deal with it for a while until PSU’s start coming back in stock, as most of the good ones seem to be sold out atm, for obvious reasons.
 
I've just replaced my EVGA 750W G2 with a 1000W Corsair RM1000X, just to be safe as I was getting the odd crash in certain games. No issue whatsoever since putting the new PSU in. (3080 owner)
 
So a 850W PSU is safe? Right?

Is there a way to undervolt the 3080's? If you can reduce the power draw it might make the coil whine go away.

I reduced the power limit by 20-30 and 40% and by the time I reached 40 the whine was practically gone but, that’s not a fix.

Honestly I’d rather buy a new PSU than reducing voltages, I plan to OC this card soon and reduced voltages won’t help lol
 
The power supplies are switch mode that switch in the KHz range. When they start to see serious power draw, the coils demodulate the KHz so you can hear it. If the coils are cheap, they will have a high tolerance band and low QA specs so they can still whine even when not driven to the max. This does not help your situation but may help you understand it :)

So I got my MSI 3080 Gaming X Trio today, I got very lucky when ordering off ocuk, completed my order at 14:05. Thankfully this isn't a crashing thread (not yet anyway)

So I installed the GPU and drivers, tested some games and was very happy with the performance boost, all was going well until I took my headset off and heard the screeches coming from my PC. I had completely forgot this happened to me before, when I upgraded to a GTX 1080 with a very old corsair PSU and now it's happening again with a 2 year old EVGA G3 750W :(

I've tested by using a toilet roll tube and putting it to my ear and going around the GPU and PSU including the back of the PSU, im 90% sure the sound is coming from the PSU as the loudest noise was coming from the back where the I/O switch is. Is there any other way to test this?

What's the reasoning behind this? Is it just because the PSU is under a much bigger workload now? Probably close to its limit?

I have a 2700X OC'd to 4.1ghz, that probably doesn't help either.

Lastly, unless anyone has a reason or a test for me to perform to prove it isn't my PSU. Any recommendation's for PSU's? :p

It's gonna sound like a weird one, but my partner got their MSI 3080 Gaming X Trio installed yesterday, and when in certain games noticed coil whine from his PSU too. Strangely, turning V-Sync on in the affected games stopped it from making the whine O_o

What hz is their monitor? I’m pretty sure coil whine is louder in higher frame rates, my monitor is 165hz so even with vsync on it’s still producing high frames. Whereas if your partner’s monitor is say, 60hz 4K for example, that might be why the whining stopped.

I play at 1440p and I noticed when I bumped my resolution scale to 200% in a certain game, even though my gpu is working harder and even though it’s not true 4K or anything, the frame dropped to like 80-90 and the whining was a lot quieter. Although I haven’t tried capping to 60fps, just for tests sake.

He plays at 1080p on a 144Hz monitor; this may be why it was okay for him O_o. Worth a try capping it for tests sake though :P

yes a decent branded 850w will be fine for the 3080 :) cheapest best option is probably the superflower leadex 3 https://www.overclockers.co.uk/supe...old-modular-power-supply-black-ca-062-sf.html
i have one with my system and never had any issues. but it does only have a 7 year warranty though. go for superflower or seasonic, or one of the other brands that superflower/seasonic make ie. the phanteks revolt pro 850w which is made by seasonic
