    Default Are any PSUs great at preventing coil whine?

    Are there any specific PSU designs that are better suited for minimizing the risk of the dreaded GPU coil whine issue?

    I understand it's a complicated issue with many factors in play, but I am simply trying to determine if any brands currently on the market are particularly suited at minimizing the issue in terms of either severity or risk of occurrence. Much obliged for any info!

    If it's any help, when I swapped mu old Antec true power 750 for a corsair hx850i my vega64 became almost silent. With the old psu it was way louder and the sound was different.

    Thanks for the reply! Alas my current PSU is a Corsair AX and my 1080 Ti Hydrocopper has some whine, but I'll keep the HXi in mind. Seems to be the highest-end model Corsair sells with FDB fans.

    Just to emphasize, I am not claiming it eliminated coil whine, just notably reduced it's loudness compared to with the old PSU. In your case it could make no difference since you already have a quality PSU.
    For eliminating and if you are brave enough, perhaps take a look here:

    Aye, but that's partly why I created this thread. I'm concerned if I do replace the PSU a new one might make the whine much worse or cause it to whine when gaming.

    I did see that post. While a neat idea the last time I used electrical tape on fan cables the tape eventually lost its stickiness and moved, allowing the exposed wires to short spectacularly against the case.

    I watercool these days, so I just don't see any reason to take those risks anymore particularly with expensive hardware. The coil whine is not major, else I would have sent the gpu back to EVGA until they could find one that didn't whine. Only a few workloads will cause it to whine (maybe 50% of Folding@home projects), so far none of them are with real games and I hope to keep it that way.

    1. is it coil whine and not (ceramic) capacitor whine?
    Those things are kinda piezoelectric things and can whine also.
    There are a couple of EEVBLOG Videos about this issue.

    2. PSU influence the accustic noise of those bloody things, but if your card whines annoyingly, you should RMA the card.
    Because it will be annyoing with every PSU.
    But with some PSU it will be louder, with some it will be quieter...


    Though its the VRM of the card that is the issue either way...

    Found that EEVBLOG video, was pretty neat to watch. I remember overclocking my E6300 to twice its frequency, and since that requires pushing the board FSB well past 500 I could induce the 965P DS3 to generate ceramic cap whine.

    Per your question I have zero idea if this GPU noise is ceramic caps or coils, but again it's only from select F@H workloads. If there's no brand of PSU with a particular penchant for minimizing whine issues then no worries, but I figured I'd check first.

    That's what I had figured. EVGA sells 3-4 different VRM designs on its 1080 Ti cards, the latest Kingpin Hydro model is 10+3 phase and is a freaking wide PCB. I'd pay for the extra power delivery, but not at 50% again the vanilla 1080 TI Hydro's price tag though.

    Unless you're buying the kingpin card to put under LN2 then it is just a waste, you're better off getting a FE card and a water block and it will clock just as high in 90% of cases
