I got in the newegg deal for seasonic m12d and I need help with this psu. This psu is constantly giving out whining and buzzing sound either my computer is on or off (i try with different computer, same result). Also, the psu gets really hot, I don't think the fan is working at all. This is my second replacement (first one has the same issue). Does all seasonic m12d have this problem (whining and buzzing sound), or i'm just extremely unlucky?
 
It sounds like you're either very unlucky, or one of your hardware components is giving some sort of feedback to the PSU which causes it to make noise. What video card do you have?
 
i tried this m12d with two different computers

i7: evga x58 with 9800gtx
AMD X2: asus A8N-SLI with 8800gtx

Both produced the same result (whining and buzzing sound which is driving me crazy :( )
 
Can you remove the video card and see if the noise is still present? If it is, then the PSU is probably defective.
 
Hm, I have a coupla M12Ds , they don't exhibit any of those defects. You might have been unlucky and gotten some from a bad batch, or as Zero82z suggests, other components may make the PSUs squeal. (It's been known to happen).
 
ya i removed the video card, the psu is still whining. also i found out that the fan doesn't start up at all!!! this is definitely defective :(. arg another rma with newegg, still trying to decide to get replacement or just get a refund. thanks for the help guys.

JoeBob, do you have the 750W or 850W?

Do you have any home appliance with Inverter ? Refrigerator, air conditioner, etc.

Some of the newer ones (especially Panasonic ones) use the cheaper 'Modified Square Wave' inverters and this will cause buzzing on most computer PSUs.
 
Well, I think you should either contact with Seasonic or Newegg for further assistance. That's just my experienced :)
