Hello guys.

Recently my PSU started to coil whine badly and i want to RMA it.

Since they can only send me the exact same product to replace it, i want to sell it then and get rid off.

Because i want to get another high end PSU that is Platinum or Gold efficency and most of all without any no coil whine issues reports.

No more corsair or seasonic based PCB's !!!

Budget not a problem, i want 750+ watts PSU.

The most ridicolous thing that if you type coil whine in youtube almost all videos comes from Corsairs PSU especially AX series !!

Any advice ?
 
Well, normally I would recommend OCZ but ya....RIP. Thermaltake is great; reliable, quiet, modular, great customer service.
 
Silverstone. But I know it is abit more expensive and less warranty (3 years) but I have 2 silverstones and no coil whines and no problem so far. (2 years now)

Superflower PSU also is good. I had one before.

Although I cannot comment on costumer service cause I never have a problem even once. My current 750w silverstone can handle 2 R9 290's with no problem altough I could hear the psu fan crank up when I tried that.

Thermaltake ? Uhmm i had one yeah fine PSU. Thank you !

No problem for the expensive important thing no damn coil whine. Thank you for the advice i would definately check Silverstone they always seemed to me pretty strong PSU.

No coil whine on the 2 corsairs and 3 seasonics I have owned


You have a one hell of a luck, because if you Google or youtube as i write in the thread coil whines are common from Corsair PSU.

And seasonic only the X series suffers from this issue.
 
Dude, you have no load on that baby of yours. My Corsair TX650 had some coil whine before when I used a measly 5770 and a Q6600, now I've stepped up to the stuff you see in the system specs and I hear no coil whine whatsoever :)
 
Coil whine is completely unpredictable, and no one on this planet can guarantee that a PSU model is free of it on every unit produced.
Most manufacturers and retailers recognize coil whine as a RMA-worthy fault, you'll just have to keep trying or learn to live with it.
 
so you dont want a PSU from 2 of the best PSU makers on the market? one of them being number 1 and MAKING the PCBs for most of the manufacturers anyway?

Wise words.

Really ? If it so i will keep it.

Because im gonna add a 780 ti and pump Phobya DC12 260 for the watercooling loop.

Tomorrow i borrow a graphics card from a friend and watch if it stops.

Also when i turn off the system the coil whine is audible.

At the moment everything is mounted on my desk.

I put 4 little rubber under the motherboard to keep it high and safe.

The AX760 is close to the motherboard.

I think they have a serious problem with the AX series and they come from Seasonic

Is not easy to identify what's inside so I avoid brands
 
Seasonic 750KM3 X series ( upto 93% according to a TPU review ), As silent as you can get.


EDIT: Maybe go buy some hot glue :P. Now i think about it don't Corsair offer cross shipping ?.

One possible explanation for so many reports of coil whine in Corsairs is because so many people buy Corsairs. What I'm getting at is that even the best companies have a fail rate on their products. A few negative reviews from a no-name company doesn't generate a lot of buzz but a thousand negative reviews on a company like Corsair does. I don't know of a way to look at the percentage of defective PSUs versus happy customers but I suspect that Seasonic and Corsair are on top of the list of best for the money and reliability and that's my own experience too.

Coil whine isn't an indication of failure. It's an indication that an inductive component isn't fully secured to the PCB and is resonating inside the PSU. If you know exactly what component was making the whine, you could secure it or something, but that requires your ripping open your PSU and I don't hink I'm prepared to recommend that. I've yet to notice much of any coil whine from my Seasonic PSU.
 
If I could shamelessly link to a previous post I made on the subject, here you can get some more details about the irritating phenomenon that is coil whine. There are some things you can try to lessen it, besides gluing the hell out of all the coils and transformers in your PSU and voiding it's warranty - see this thread.
 
You can't say "no more seasonic based psu's" it's too random. The corsair AX860 I ordered from amazon a year ago had serious coil whine so I RMA'd it and the replacement is totally silent with no hint of coil whine for a whole year now... Cert there are a lot of complaints about the AX series coil whining but consider the amount of ppl buying Corsair + Seasonic PSUs vs other brands and consider the probability that the first batches of the AX series had this issue too frequently and it has been dealt with since then.

Other than that my flatmate bought a 700W gold Silverstone it seems rly good quality.

Also, as mentioned above the coil whine of the PSU varies with the components in the system, changing the GPU can stop or increase coil whine (or the GPU can coil whine with a PSU but not with another).

seasonic only please.
 
NZXT has started glopping up their psu's in an attempt to limit coil whine issues- see pic:

Review here if interested:
http://www.hardwaresecrets.com/article/NZXT-HALE82-N-650-W-Power-Supply-Review/1565/1

I recently picked up one of these NZXT models and found the same treatment on it. The material used looks like some form of dense spray foam.
 
Actually, most manufacturers do that, and it's white silicone caulk (heh). Hi-temp and high dielectric strength, non-corrosive, just as it should be. I've seen more extreme examples, too. Actually, Listan/BeQuiet!, for example, caulk up *snicker* their PSUs rather extensively, but they use big black caulk *giggle* blobs - probably because they're German, and their genetic technical OCD won't let them use any other color, when they have everything else done in black.

Since caulk isn't exactly rubber, and does get hard (oh come on) over time, it's ability to absorb vibrations is somewhat limited, thus it's extensive use doesn't guarantee coil whine elimination. Plus, too much of it will hinder cooling since it's a pretty good thermal isolator, so that's another thing that mustn't be overlooked...
 
Coil whine has been around for ever, they used to use a wax like substance back in the day but i guess they cannot do that these days due to heat. Just the copper not tight enough.
 
OP, consider EVGA's G2 or P2; Super Flower platform with a 10 year warranty.

Not a price at the moment either: http://www.newegg.com/Power-Supplies/BrandSubCat/ID-1402-58?Order=PRICED

Haven't had a problem with my AX760, just for the record.


They dont sell the Evga 850 G2 in my nation, only the 1000 G2 and above are available.

Same price as US.

Well you are one of the lucky one that have a AX760 coil whine free sample.


Im thinking to get the Cooler Master V850.

Thanks for all !

Be warned:eek:, I think the CM V series uses Seasonic KM3 internals.

I doubt you'll get another dud though.

Best of luck!
