    SeaSonic Platinum XP2 "Coil Whine" - Thoughts?

    I have been watching the PSU market & digging into gory, detailed torture tests on PSU's as I often do.
    I have found this amazing PSu by SeaSonic: SeaSonic Platinum 660XP2 - Johnny Guru Review (Teardown+Torture Test)

    It's on beauty of a PSU in just about every aspect, many review websites are either referring to it, or just about, as the best PSU on the market /w perfect power.
    Using all Chemi-Con and Rubycon electrolytics /w Enesol polymers.
    One problem though.....
    IT HAS COIL WHINE!!!
    Seriously?

    Granted, no product is ever perfect, doesn't happen. I have looked for decades... to no avail.
    But seriously, coil whine.... in a PSU???

    If you read the reviews over @ the Egg: SS Platinum "Coil Whine" Reviews
    You'll see that there are a lot of units that buyers are receiving with this problem. Supposedly they fixed it in a 2nd revision a few months back, but according to new reviews, that's not the case. Assuming they know what they're talking about of course.

    What are the thoughts on this situation? What causes coil whine, and is it really that, or is it capacitors doing it?
    Could it be those Enesol polymers that no one has seen die on here, but some members thoroughly dislike?
    Anyone used this PSU?


    On a side note....
    I'd like to go with a smaller wattage unit for this system, for efficiency sake so it's as close to the 40% minimum power consumption as I can. But I really, really, really.... X1,000 hate the idea of a "fanless psu". It scares the bejeebers out of me!
    PSU's evacuate a fair amount of heat from traditional top mounted systems. It just naturally collects there. That and component life reduction from the higher heat of the internal components.
    Thoughts, arguments, real world application & use of fanless PSU's in systems that aren't exactly "cool as a cucumber" so to speak??

    Coil whine is caused by vibrations within the windings of the transformer/inductor. Capacitors CAN cause coil whine, when they are of the incorrect capacitance and/or esr. This is due to either high peak currents, or control loop instability.

    One way to try to fix coil whine is to re-varnish the transformer.

    To find out exactly what is whining, put a straw up to your ear, and probe around inside the psu.

      ADP-160FR ps4 slim PSU, shuts down under load and has severe coil whine.
      by Gjackson
      Hi all, the PSU originally had a no 12v issue where as soon as I bridged the 5v standby to the ACDC_stby the psu would switch itself off completely. I monitored the voltage on the main filter caps while doing this and saw that the PFC was bringing the voltage up to around 360vdc before shutting down. Given that I saw that as a little low I replaced the PFC feedback resistors from a donor PSU and that got it to power on, without a load no coil whine is present and there is a stable 12v however as soon as I put it in the PS4 it starts whining really badly, however 12v remains stable but after a...

      Seasonic Platinum 860W No Fan Spin
      by CallumUK
      Hello
      I am a novice here but electronics enthusiast and general all round tinker.

      I have a Seasonic Platinum Series 860W PSU which does not turn on my PC. I get no fan spin and I have used the jump start method with the PSU out of the case and it doesn't turn on either. I believe this PSU doesn't need a load to begin working.

      I didn't see any bulging caps, burnt areas or burnt smell from the PSU.

      This is the same PSU as in this review: https://www.anandtech.com/show/5464/...-series-860w/4

      I have gone as much as using...

      LG Flatron starts w. coil whine and power issues
      by Bitvive
      Hi ,

      My old LG Flatron recently started with coil beeping. This got worse every day for a few days until it also started having power problems.

      Now it also went off again after displaying the LG logo, then on, off again, then on and so on...

      So far I have measured the power supply unit, which delivers 19.21V and should therefore be OK. I removed the circuit board and connected it to the mains plug so that I could hear the coil beeping.

      During the beeping, I pressed on the coils with a non-conductive tool to see if the sound changed and to find...

      Coil Whine , buzzing, identifying parts R9 Fury
      by 90Ninety
      I have an R9 Furty Nano ( R9 2XX IIRC ) that I want to put to use , I got it on ebay for quite cheap but, it has some of the worse coil whine I have heard .

      I tried putting a long tube on my ear and hovered it around the card while in use , I cannot pinpoint it . However I my educated guess is , that it the whine is an inductor coil and it is one or all of these in the picture . Does anyone know what part this is and what part I can replace them with .




      Perhaps likely is that I am missing something else it could be , here is a stock picture...
