eshbop Posted February 20, 2013 Share Posted February 20, 2013 Hi, Several days ago I bought this PSU and after flipping the switch on the back of the unit before powering on the system was faced with a quiet annoying and distracting sequel (especially when trying to sleep). Part of the reason I bought this PSU was due to its fanless operation but this noise is much worse than the 'whoosh' of a fan. After some testing I found that no matter what system I put it in, what wall socket, what I did to CPU power settings (which imho is not a fix) the sound would not go away. Turns out all that is needed for the sound to start is the 24pin plugged in. The sound is also present (although in a slightly different pitch) when the computer is on, both at idle and under load. So I sent the unit back to where I bought it and they sent back a replacement, which has the exact same problem. I really like this PSU (apart from the whine obviously) and was wondering the commonality of this problem (it seems like a few people are having this issue with the new AX's), ie; if I send this unit back again, what are the chances of me getting another squealer? It's already cost me AU$250 (+$20 more if i send this one back) Or is it not worth my worry, should I just pick another PSU altogether? I don't really want to be spending $350 to find a PSU that doesn't keep me up at night... Cheers for the help! Link to comment Share on other sites More sharing options...
spikexp Posted February 20, 2013 Share Posted February 20, 2013 I can confirm the problem, I just got my ax760 to replace my new tx750. From what I heard, the problem might go away after some time (not too long). Link to comment Share on other sites More sharing options...
shawnoen Posted February 20, 2013 Share Posted February 20, 2013 Nothing wrong with your system, Corsair wont address the issue so youll just get another one that makes noise. Loose windings inside the transformer is the source of the noise. Link to comment Share on other sites More sharing options...
eshbop Posted February 20, 2013 Author Share Posted February 20, 2013 Hmm I see. Does anyone know if the AXi's have the same problem? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted February 28, 2013 Corsair Employees Share Posted February 28, 2013 Did you get it replaced via our RMA process the first time? if not, I would have it replaced through our RMA and we'll make sure that the replacement will not have this issue. Once you have submitted the RMA request, post your case # here and I will make sure that we take care of any shipping expenses both ways. Link to comment Share on other sites More sharing options...
eshbop Posted March 1, 2013 Author Share Posted March 1, 2013 No, I didn't return though you guys. There's no AX760W (Australia) option in the RMA request page, should I just pick one of the other options? Link to comment Share on other sites More sharing options...
eshbop Posted March 1, 2013 Author Share Posted March 1, 2013 Also, I'm looking to get 3x 600t Frontmesh, do you know if it would be possible to package them with the return PSU to save shipping costs? I'd be happy to pay the difference. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 2, 2013 Corsair Employees Share Posted March 2, 2013 Unfortunately no, the order type is completely different, and they're handled differently in our system. We're truly apologize for this inconvenience. Link to comment Share on other sites More sharing options...
eshbop Posted March 2, 2013 Author Share Posted March 2, 2013 No worries. I just chose the AX760 (North America) option in the RMA request form, as there is no option of Australia. The RMA number is 5691265. Thanks for your help, much appreciated! Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 5, 2013 Corsair Employees Share Posted March 5, 2013 I have asked our customer service to take care of this for you and send you an AX760i PSU as a replacement. You should hear from them shortly Link to comment Share on other sites More sharing options...
eshbop Posted March 26, 2013 Author Share Posted March 26, 2013 Hi, I got a AX760i as a replacement yesterday. It has the same problem as the unit I sent for RMA. As this doesn't appear to be 'as common' in the AXi as with the AX I tested it more extensively than described in the 1st post. On top of what I did described in the 1st post I went to 2 friends houses and tried it in their systems (so far test with 1 Asrock, 2 Asus, 1 MSI & 1 Gigabyte board, all with different GPUs). The problem persists in all of systems. I would of probably put up with it but the new unit has a significantly louder whine (especially when the PC is off) compared to the 2 units I've sent back (also with a background clicking). Also, Corsair Link shows the PSU at only ~75% efficiency when at around 45% load. I know the software may be buggy or the readings off but ~15% deviance (given a typical inefficiency of around 90% at that load) seems a lot given review sites only show a 1-3% deviance from their own hardware testings of efficiency. Assuming the RMA is accepted can I get the AX760 (non digital version) as a replacement? If it happens to have the same problem (and is no louder than the 1st 2 units I've sent for RMA) I think I'll just live with it. Thanks. Link to comment Share on other sites More sharing options...

VasVas Posted March 30, 2013 Share Posted March 30, 2013 My AX860 use to make the exact same noise, completely gone after a few weeks of use.. Link to comment Share on other sites More sharing options...
eshbop Posted April 9, 2013 Author Share Posted April 9, 2013 Hi, is there any update on this? I got a message on 3/28 but nothing since. "I saw your post and sorry to hear that. You have done the proper steps to make sure that it was indeed the PSU causing the noise. I will let customer service know that you would prefer the AX760 non i version and we'll go from there. Thanks" Should I get a new RMA number or will the previous one (5691265) be used? Thanks. Link to comment Share on other sites More sharing options...

WOW, i wish you made me that offer, the only reason i sent it back to Ebuyer.com was because it was in the 28 day peroid and they cover the first £10 (uk pounds) of the return postage, after paying out £150 on a psu another £25 plus to send it back to the neverlands was just a bit to much, but still nice to see someone getting very good customer service, glad i got Corsair now, even if mine did die in two hours off use :( Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted April 11, 2013 Corsair Employees Share Posted April 11, 2013 I am sorry about that but you would have had to call our customer service by phone to work out the shipping but we will take care of the shipping if its less than 30 days old on any RMA. eshbop I answered you on another thread Please dont double post!
