PSU causing coil whine.

Hi,

 

I recently changed my GPU from a GTX 780 to  GTX Titan thinking that my 780 just happened to have quite bad coil whine. To my despair the Titan has roughly the exact same type of coil whine in my system but did not have any coil whine in a friends system. Would it be possible that my Corsair HX650 PSU is causing the coil whine in both cards? I've been trying to get my system to be completely silent with water cooling and having only SSDs but these ordeals really make me want to sell the damn thing and get some small black box like the Silverstone SG13 that just works.

yeah, could be the PSU. some PSU/GPU combos just make dirty whines.

We can't Benchmark like we used to, but we have our ways. One trick is to shove more GPUs in your computer. Like the time I needed to NV-Link, because I needed a higher HeavenBench score, so I did an SLI, which is what they called NV-Link back in the day. So, I decided to put two GPUs in my computer, which was the style at the time. Now, to add another GPU to your computer, costs a new PSU. Now in those days PSUs said OCZ on them, "Gimme 750W OCZs for an SLI" you'd say. Now where were we? Oh yeah, the important thing was that I had two GPUs in my rig, which was the style at the time! They didn't have RGB PSUs at the time, because of the war. The only thing you could get was those big green ones.

It's not that the PSU is causing coil whine in the graphics cards, it seems that your PSU simply has capacitor whine. It's fairly common in components that have large capacitors and even if you don't have it at first it's entirely possible that a PSU can develop it after a couple years of use. You could try switching it out, but you're probably stuck with it because manufacturers don't consider it to be a reasonable defect due to how common it is.

have you tried your system without the gpu in ? coil whine comes from gpus when theyre pushed to a limit, i get coil whine in the far cry 4 menu because the fps is like 2000.

I did ask Corsair earlier about this and it seems like they would exchange it to a new PSU but then again that would probably just be another HX650.

Changing the HX650 to another HX650 probably won't fix it then.

 Trying the system without a GPU is a bit hard since it's water cooled. But I did run it without a GPU some time ago before I had a custom loop and the coil whine was of course gone since it comes from the GPU not the PSU.

so its possible that the new one also has coil whine, a lot more of the newer gpus have coil whine, its just one of them things bro.

no, it wouldn't.

 

i suggest borrowing a PSU as a loaner and trying that.

We can't Benchmark like we used to, but we have our ways. One trick is to shove more GPUs in your computer.

It didn't have any coil whine in a friends system whom I bought it from.

Would probably be the best thing to do but I doubt I'd be able to find a loaner.

ask a local shop if you can barrow one.

 

i became friends with my local dudes and they let me test parts all the time.

 

ram broke? IDK, let me run it on their test bench!

Also a great option but there isn't really a local shop anywhere near me.

 

I'm thinking about just getting a new PSU and I've only heard good things about this model: http://www.newegg.com/Product/Product.aspx?Item=N82E16817438017 .

 

Corsair sound willing to replace my HX650 but the shipping from Finland to the Netherlands is pretty expensive and another HX650 probably wouldn't fix the issue.

I'm looking at getting something used from close by since I wouldn't want to splurge on a new PSU if it doesn't fix the whine. Do you think the character of the whine could be a clue that it's the PSU causing the whine since it's quite a low electrical buzz and not a high pitch squeal that's almost identical on both cards?
