Coil Noise Free PSU

Hi there, all u need is a good one and @ 600W u have a plenty

to power your machine : ))

This one is @ 650W, but its a great deal on great PSU.

And its way more than u need. But the price is right.

QUIET COOLING
An ultra-quiet double ball-bearing fan delivers excellent airflow at an exceptionally low noise level by varying fan speed in response to temperature.

SUPERIOR PROTECTION
Over-voltage and over-current protection, under-voltage protection, and short circuit protection provide maximum safety to your critical system components.

Thanks for the quick reply. Do you know what the coil noise it like on the tx650?

I don't own this one, but its pretty quiet one with long cables!

I build one PC with it and its as quiet as my Seasonic. Don't even know its there.

If u touch it, u feel its running, but no noise.

Seasonic built unit, high amps on the 12v rail, 80 plus bronze certified, runs quiet, good build quality, heavy (typically a good sign with power supplies), reasonably priced,

5 year warranty, Corsair = reliable brand

That could be the fan, the coils don't make alot of noise unless they are damaged, shorted or are about to die.

Thank's Nikkor i'll definitely check that one out. I was also thinking about the Seasonic x series. Any thoughts on this?

I'm not sure what it is to be honest. All i know is that the PSU starts making a buzzing sound the second I open any games. Even games that aren't very demanding, like Minecraft. Also, it makes a high pitched squeal when I run the Windows Experience Index assessment.

Same thing with Seasonic.

I have M12II and its quiet, that's why I got it.

The Seasonic X is premium class.. Loaded with the best in PSU business : )


The X Series adopts a clever “Hybrid Silent Fan Control” design, which offers three distinct operation modes, fanless mode, silent mode, and cooling mode.

The X automatically adjusts fan mode and speed according to the ambient temperature level. This brand new design not only optimizes heat dissipation, but also prolongs the lifespan of the system by reducing unnecessary fan rotation.

To make the X Series even more robust and exciting, Sea Sonic offers a Sanyo Denki San Ace PWM Silent Fan, the best fan there is in the industry, to take advantage of the PWM feature.

When its makeing the noise, try putting you ear near the fan.
See if its coming from the fan by stopping it for a while.

Good idea - will give that a try. How do you suppose I go about stopping the fan?

So i'm not likely to experience any coil whine with the seasonic x series?

Nope.

Most likely u will never hear that again, with different PSU as well.

Some thing thats not electrically conductive (cocktail stick), just try and stop the fan by putting the stick where the blades are spinning.

U can try to open the PSU and see from close up, whats up with that.

Ok might give that a try. Not sure there's much point though; from what I've read online it's fairly common with the GS series PSUs.

What papers are missing from the PSU?

Everything. I threw away the box and forgot I had left all the papers in it. The main thing is I don't have the invoice.

U are like my wife, she throw away every box that comes in : )

She says, that I have a hoarding problem : )

That keeps me organized, lol

lol   I didn't even think I'd need them. I just assumed it would be fine because it was made by Corsair. Hopefully i'll have better luck with the new one

Well, Corsair uses Seasonic guts in most cases : )

Yeah I think ur right with their higher end ones but I don't think the GS800 is

Yep,

The GS800 is made by Chanel Well

Who is the manufacturer of your PSU?

Thanks for that link. That'll come in quite handy when choosing a new one to buy

Sure thing.

Hi shaunacres,
I've had 3 seasonic x660's in a row make an annoying coil whine and buzzing sound which can be heard across the room.
Really frustrated, got the x660 specifically for its silent operation.
Definitely the x660 making the noise. All three emitted this same noise when started with a paperclip with nothing connected.
Some mentioned this noise is a result of their high efficiency, much rather a less efficient, silent PSU.

Emailed seasonic USA and asked whether it would be worth returning PSU again or would I just receive another noisy one, their reply was:
"It's still worth a try, however, I don't guaranteed it"

Reviews read (hardocp, xbitlabs, anandtech) when deciding on a PSU all said the seasonic x series was great and totally silent when the fan isn't spinning but none mentioned this noise?

Whirlpool thread where I've whinged about it and others have mentioned a similar noise:
http://forums.whirlpool.net.au/archive/1942352#

Not sure what to replace it with, if seasonic parts are in corsair PSUs, will they buzz aswell?
Any kingwin, x560 or x460 fanless owners have this buzzing noise?

Sorry for the late reply if you've already bought it.

Hi Douglas,

Thank you so mucn for your reply. Luckily I haven't ran out and invested in it just yet. I decided to live with the noise for now until I get a bit more money for a decent power supply. Please do let me know if you find a suitable one and if I find one I will be sure to post on here. Grrrr it really annoyes me how manufacturers simply don't test for these sort of things.

Coil whine is definitely a luck of the draw kind of thing.
I suppose it is also the case that some people are more likely to notice unwanted noises compared to other people.

A better link for PSU information:
http://www.realhardtechx.com/index_archivos/Page541.htm

Super Flower built PSUs (eg Kingwin Lazer Gold / Lazer Platinum, Rosewill Capstone) don't seem to get criticized as often as some Seasonic built PSUs for coil whine, but this might be that more people buy Seasonic PSUs despite Super Flower being as good or better. So there are less people to potentially complain about anything.

The SilverStone Strider Plus and Strider Gold / Gold Evolution series have capacitors attached to the actual cables, one of the supposed advantages of this is less likelihood of coil whine.

Thanks very much for that. I'll definitely look at those brands. Have you had any personal experience with any of those, if so can you make any recommendations?

No, I've only ever bought one PSU and I managed to get one which hasn't presented audible coil noise so far.

Uploaded a recording of the x660 to youtube:

Any Seasonic owners notice this noise?

I still can't find a silent replacement.
