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

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
 
Not sure, but I would hope the recommended 750W would have had some consideration for not overstretching the PSU.

Linux Tech Tips recently was running a founders edition 3080 on a 650W for a small PC build with Ryzen 3900xt (https://youtu.be/Z2s-q34FX7c) and I am fairly sure he would have complained if any coil whine.

Only way to be sure if problem is GPU or PSU is to test your GPU in someone else's PC and see if the coil whine happens there.
 
Are you using separate cables for the 2 or 3 pins on the 3080? Or you using a daisy chained one for 2 of them? If you are that could be the cause of the coil whine pulling 300w out of the psu on a single cable could be to much for the powerfully on that rail. Try changing the cables around. Coil whining can be caused by a lot of reasons though but that my best guess

This. I think I read that the pcie sockets are supposed to deliver a max of 150w each. If you are using one of those 1 to 2 cables, you’ll be pulling more than double that for a 3080

I know, I was surprised myself. I’ve seen youtubers running the 3080 fine on a 650W and even a 500W

Okay so my PSU has four VGA ports and comes with four VGA cables, two of those cables are single ended and two are daisy chains. So yes I have 3 separate cables plugged into the card but one of the cables is a daisy chain cable, but the extra connection isn’t plugged into anything. Surely this wouldn’t be the cause? I mean that’s all the GPU cables my psu came with so it’s the only setup choice I have.
 
This might be a stupid question, but how many rails is your PSU? With some PSUs you need the VGA outputs plugged into specific places depending on the number of cables you're using.
 
I've just swapped from a Corsair RM850X to my other, similar FSP Hydro G (850W 80+ Gold).

Not sure if it was whine, but could hear electrical noise from it. I also swapped out the fan from the FSP to a 140MM BeQuiet case fan as the old one was noisy.

This is still with my 2080, but I'm sure it's going to be ok when my 3080 gets here.

It should be okay

Do you have another computer you could test the card in, or another PSU you could swap in for a test?

I do yeah but not right now, it's a friends. Would maybe be next week or the week after before I can get testing.

I don't know much about rails or anything but from a quick google search, my PSU is a single 12V rail.
 
This is more of a solution for coil whine coming from the graphics card but you could give it a try.

I had issues with coil with my old Pascal card years ago but I was able to fix it by running the Heaven benchmark on a constant loop overnight. You could try the same and maybe add a CPU benchmark (like prime95) at the same time to give your PSU a workout. It might also be electrical interference from other electrical devices as well, including wireless ear buds, microwaves, alarm clocks etc.
 
Okay so I just tested it with one regular VGA cable and one VGA daisy chain cable, just to see, and the coil whine has actually been significantly reduced.. I've heard a lot of reports to stay away from daisy chaining with these 3080's but, the coil whine is def less obvious when I use one although it is still there.
 
buy a better PSU, test it, if it doesn't stop the whine, return it within 14 days and return the 3080 too :p

these cards draw insane power, if there is a lot of shiz plugged into ur PSU or u overclock cpu/gpu heavily then it will likely be putting a big strain on the psu. the msi gaming trio is especially power hungry, doesn't it have like 3 power slots? are you plugging all 3 in from the same single power cable? im not even sure if they make power supplies with 3 seperate pci-e power cables xD but guess they must do somewhere.
