yr_bluescreen Posted May 18, 2013 Share Posted May 18, 2013 Dear all, Three days ago I made a purchase for two new AX1200i PSUs from scan.co.uk Both of these were installed on two new separate systems, and both appear to work just fine. However, both suffer from a very loud and annoying electrical buzz. It's impossible to sit close to the computers as it drives me insane and so right now I'm using a pair of headphones to work in the presence of the computers. I have tested both PSUs without any load (just plugged them into the socket) and the noise was still there. A surge protector doesnt do the trick as well. This doesn't feel right and I don't understand how what on earth is going on? Has there been a batch of bad AX1200i PSUs or what? Someone made a video of this problem and this is EXACTLY what my PSUs do: http://m.youtube.com/#/watchv=ItpNIAgF4jw&desktop_uri=%2Fwatch%3Fv%3DItpNIAgF4jw I have been using corsair PSUs for over 5 years and have NEVER come across this problem. At this point in time I have sent one PSU back to Scan for a refund and I need the other one for work as the old one has been sold. What should I do? Is an RMA possible? Have there been any recent reports of this? Your help would be greatly appreciated. Link to comment Share on other sites More sharing options...
peanutz94 Posted May 18, 2013 Share Posted May 18, 2013 Yes, it can be RMA'd. However since you have two of them doing the same thing I'm wondering if your ouutlets are not properly grounded. These digital PSU's are pretty sensitive to that sort of issue. But at any rate Just use the link on the left to request an RMA. Once you receive your RMA number you can call CS on monday(Corsair is closed on the weekends. and ask for an advanced replacement if you need one in a hurry. Oh and if you use SKYPE it's a free call from anywhere in the world. Link to comment Share on other sites More sharing options...
yr_bluescreen Posted May 18, 2013 Author Share Posted May 18, 2013 Hello and thank you for this information - very much appreciated. I have just tried to power the PC through other outlets and the same thing happened. Do you think a problem in the grounding permanently damages the PSU? I guess that would explain why it still buzzes if that is true. I'm no expert, but a grounding problem would result in decreased ability to regulate voltage spikes, is there something one can buy to help with that? Thanks again Link to comment Share on other sites More sharing options...
brewster0101 Posted May 19, 2013 Share Posted May 19, 2013 You want to RMA these through Scan. Sending them to Corsair will cost you a small fortune. Scan should arrange to pick them up at their cost. Link to comment Share on other sites More sharing options...

Brewster , i am sorry but you are only partially correct. While in most cases you would be required to pay for shipping, but since these units are less than 30 days old Corsair would pay for the shipping charges. Once you have applied for your RMA and received a number you can call CS and ask them about a pre-paid label. Link to comment Share on other sites More sharing options...
yr_bluescreen Posted May 20, 2013 Author Share Posted May 20, 2013 Thank you both for the input. I will fill in an RMA and give CS a call. I just hope I could get a little more input about the buzzing sounds. Does anyone else here want to share some thoughts about the buzzing? Has anyone had these problems with the AX1200i and if so how what did you do to get them fixed? Thanks again guys. Link to comment Share on other sites More sharing options...
peanutz94 Posted May 20, 2013 Share Posted May 20, 2013 Does anyone else here want to share some thoughts about the buzzing? Has anyone had these problems with the AX1200i and if so how what did you do to get them fixed? Is there anything specific that you noticed that makes it "buzz"? Or does it do this all the time? Have you tried any of the suggestions outlined in the Noisy PSU sticky? http://forum.corsair.com/v3/showthread.php?t=85166 Does anyone else here want to share some thoughts about the buzzing? Has anyone had these problems with the AX1200i and if so how what did you do to get them fixed? The link you provided returns a 404 not found error. So without being able to hear it , it's pretty hard to tell. Disabling some settings in the BIOS may help , could be as simple as that. There have been other users reported fan controllers that would buzz when the fan kicked on/off too. But other than that there is no way to fix them. Opening the case voids the warranty. Just out of curiosity, back to the grounding thing...is this an older building? And do you have GFCI outlets installed anywhere? Link to comment Share on other sites More sharing options...
yr_bluescreen Posted May 20, 2013 Author Share Posted May 20, 2013 Hey again, First thing, sorry about the video, here is the proper link: As for the suggestions in the PSU sticky, yeah I have given those a try and the PSU still buzzes. I do have to point out that the disabling the Intel Speed Step Tech might of made a tiny improvement, but again its marginal and at times it gets just as bad. What I can say is that the first 3-5 seconds during power up the PSU does not buzz. Thereafter it starts. I also noticed that when I disable my graphics card in the device manager, the PSU begins to crackle and buzz. It almost feels like something is gonna melt inside. The crackling stops but the buzzing continues. When I enable the card, the same crackling noise comes back and 2-3 seconds it goes away. Not sure if this tells me anything. As for the GFCI outlets, no I don't :( Link to comment Share on other sites More sharing options...
Mikesnow Posted May 24, 2013 Share Posted May 24, 2013 If you have one of the apc stlye surge protectors and you plug it into the wall and the light lights up red claiming site fault wiring or such then you'll prolly want to get an electrician out to check the house wiring. There is a bare copper wire in the romex wiring that should connect to the 3rd prong of the outlet, then in the breaker box it will transfer out into your meter can and then down to a solid copper ground rod that is about 6 - 7' long hammered into the ground. Even if your new one don't buzz you should insure your plugs are wired properly. Link to comment Share on other sites More sharing options...
peanutz94 Posted May 24, 2013 Share Posted May 24, 2013 hen I enable the card, the same crackling noise comes back and 2-3 seconds it goes away. Not sure if this tells me anything. As for the GFCI outlets, no I don't :( I would go ahead and have it replaced. But if you get a second unit that does the exact same thing then i would think about looking at possibly your other hardware . Just use the link on the left to requet an RMA and since the unit is less than 30 days old you can also request that corsair pick up the shipping costs. Or you always have the chance to have it replaced at your resellers if that is faster for you. Please let us know how you make out! :) If you have one of the apc stlye surge protectors and you plug it into the wall and the light lights up red claiming site fault wiring or such then you'll prolly want to get an electrician out to check the house wiring Yuppers! And there are many cheap line testers available at most home improvement centers or hardware stores. It might be something to look into especially if you live in an older dwelling There is a bare copper wire in the romex wiring that should connect to the 3rd prong of the outlet, then in the breaker box it will transfer out into your meter can and then down to a solid copper ground rod that is about 6 - 7' long hammered into the ground. Even if your new one don't buzz you should insure your plugs are wired properly. The only thing I can add to that is even if you have a ground rod hammered into the ground, that doesn't necessarily mean it's a "good" ground. Just something else to keep in mind. Having a background in industrial construction, i have seen them corrode or the connection loosen up over time. Link to comment Share on other sites More sharing options...

yr_bluescreen Posted September 1, 2013 Author Share Posted September 1, 2013 Problem still persists even after fourth RMA. This is just ridiculous! One of the PSUs makes less buzzing noise then the other though. I might have to switch from CS, and I really don't want to do that. Link to comment Share on other sites More sharing options...

Wow, it's so obvious that something is wrong with those PSU's...My case is similar as yours.. my 3rd replacement make less buzzing than the two previous one but it's still there! They even tested it before sending it to me and I've been told that there was no noise... I really don't know what to do now.. because there's 99.9% chances that the 4th one will buzz as well. Please Corsair, fix your darn power supplies :!: Link to comment Share on other sites More sharing options...
JKeifer Posted September 1, 2013 Share Posted September 1, 2013 As mentioned above, the power coming into the power supply could be the problem. Not only is miss-wiring a problem but direct current (DC) riding on the incoming AC can play havoc with power supplies. If you have a DVM that can read DC, I'd check to see if you have DC riding on the wiring. If you have more than a volt or two, that very likely is your problem.

Corsair Employees RAM GUY Posted September 3, 2013 Corsair Employees Share Posted September 3, 2013 Ex0ticViru5, What was your previous RMA#? And are you using an APC or battery backup? Also is the out let you have this plugged into properly grounded? Link to comment Share on other sites More sharing options...
Ex0ticViru5 Posted September 4, 2013 Share Posted September 4, 2013 Ex0ticViru5, What was your previous RMA#? And are you using an APC or battery backup? Also is the out let you have this plugged into properly grounded? Hey RAM GUY.. I'm only using a standard power surge protector, no UPS. My previous PSU was a HX850 that I've used for almost 5 years without any issues. It was also dead silent, never had any kind of coil whine noise. The electrical noise (coil whine) issue only started when I've the swap from my HX850 to an AX1200i. The PSU has even been tested by Kelvin before you sent it to me. I've been told that there was no noise. Maybe the coil whine only happens when the PSU is connected to an actual motherboard and not on the PSU test bench you're using. The cause might be the lack of glue on the coils to prevent them from vibrating, bad capacitors, etc. I love Corsair but i'm on my 3rd replacement and the problem is still there... If the issue can't be solved, I will have no choice but to change brand even if I don't want to... Anyway, here's my last RMA# 6081813. Link to comment Share on other sites More sharing options...
yr_bluescreen Posted September 12, 2013 Author Share Posted September 12, 2013 Ex0ticViru5, Sorry for the late reply. I've now moved houses so did not have access to the internet and even now it is temporary. Yesterday I powered up my PC in my new place... I was really hoping that the modern circuits here would help with this noise issue - but nope, it was too much to ask for. The noise is still there. Also, the PSU started doing is emitting this noise even when the PC is OFF!! The sound is so nasty that I have to turn of the PSU manually, because I can hear this sound in the other rooms. There must be something that be done about this. S. Link to comment Share on other sites More sharing options...
misiak Posted February 25, 2015 Share Posted February 25, 2015 Hi I would like to resurrect this topic. This issue is getting me crazy. Here's my story: I bought HX1000i, connect everything, turned on and was really happy. Then during the night in silent room (because I have almost noiseless system - 3x Noctua fans on 400 rpm in idle are inaudible) I realized something is making a very low electrical constant buzzing sound. So I turned off the PC and the buzz was still there. I put my ears to the case and the noise was louder. Then I put my ears on the metal case of PSU and here we go, TRANSFORMERS buzzing. Usually this is not a problem, but if you have super silent PC you want to have super silent PSU. OK, I thought it was a bad luck so I've ordered RM750W instead and guess what, exactly the same buzz from transformers. So, I told myself I will abandon corsair and bought Seasonic X 750W.... And ? The same buzzing as corsairs... Then I've read somewhere that transformers in corsairs are provided by Seasonic :) So I don't know what brand produce PSU with non buzzing transformers.... Now I'm asking myself, is there a PSU which is not making any noise in standby mode ??? With PC turned off ? I have an older Antec 520W and there is no buzzing whatsoever so this needs to be some manufacture flaw. Link to comment Share on other sites More sharing options...
Corsair Employees jonnyguru Posted February 25, 2015 Corsair Employees Share Posted February 25, 2015 Then I've read somewhere that transformers in corsairs are provided by Seasonic That is a blatent lie.

giltyler Posted February 28, 2015 Share Posted February 28, 2015 That is a blatent lie. Curious as to where you read that. Some of the Corsair units were/are OEM built by Seasonic that much is true. No matter the OEM they are all built to Corsair's specifications. Link to comment Share on other sites More sharing options...
Corsair Employees jonnyguru Posted February 28, 2015 Corsair Employees Share Posted February 28, 2015 Right.. Read what I quoted. The implication was made that whomever actually makes Corsair's PSUs, Seasonic makes the transformer and that just patently false information.
