Bobby Bec Posted November 25, 2010 Share Posted November 25, 2010 Hello, i decided to upgrade my PSU and after i read a lot of reviews about how good ax 850 is,i bought it. Then i noticed that the PSU is making electrical noise every time when there is cpu load.It doesn't matter what i do , loading windows playing games or run some stability tests like prime 95. When my pc is in idle the noise goes away. What i did trying to fix this : I did everything suggested in the Noisy PSU thread replaced my motherboard with P7P55D EVO - same noise replaced my video card MSI N470GTX Twin Frozr 2 with Asus 9800 GTX+ and then with Asus 8800 GTS -same noise i did try with Different hard disk to - same Then finally asked a friend if i could use his pc which has very different setup - GIGABYTE motherboard,CPU Phenom II and ATi HD4670 and the PSU was making exactly the same noise So after i was sure that there is something wrong with this PSU I went ahead and returned it to the retailer so they can test it and possibly replace it. My surprise was after they called me and told me that indeed the PSU is making noise but they are not going to replace it because they opened 2 more new ax 850's and both had the same electrical noise so this indicate its normal behavior of this model PSU. So now i cant return it and get my money back I also cant replace it because all of the AX 850 they have are acting the same way . I also cant use it because the noise is loud and really annoying and this is coming from PSU which is supposed to be one of the best 850w power supplies on the marked.

slyphnier Posted November 28, 2010 Share Posted November 28, 2010 i am owner of AX750 it seems its little issue AX series have rather than CPU, i think it more have relation to GPU, especially power-hunger GPU, i am using ATI5850 and my psu did make some electrical noise when using GPU power mine run silent when running prime95 you can try to ask your shop to look newer revision PSU i don't know what the newest PSU corsair release, maybe RamGuy can help providing some revision info here? my friend who bought AX750 a month after release get revision A0W, i think that is first version... mine is revision A1W hope helps Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted November 30, 2010 Corsair Employees Share Posted November 30, 2010 How loud is the noise? How far away does your head need to be from the PSU so that you can not hear it? Link to comment Share on other sites More sharing options...
Bobby Bec Posted November 30, 2010 Author Share Posted November 30, 2010 Hello, in my opinion it is very loud,in fact its the loudest part in my pc now and i do have 6 fans in my case. I can hear it from like 2-3 meters away during the day and at night it is even worse. Link to comment Share on other sites More sharing options...

Corsair Employees RAM GUY Posted January 24, 2011 Corsair Employees Share Posted January 24, 2011 Looks like the RMA has already been approved and you should be ready to go. I will resend the confirmation which should have all the instructions for the replacement. Link to comment Share on other sites More sharing options...
Timmay284 Posted March 2, 2011 Share Posted March 2, 2011 I just bought the AX850 and I have the same problem. I was wondering if this RMA fixed your issue or is it still making the buzzing sound? Thanks Link to comment Share on other sites More sharing options...
