Strange PSU buzzing tied to HDD!?

Well, I can safely say that I will probably never buy from Seasonic again. The new "guaranteed not to buzz" power supply buzzes just as bad as the one I returned. Plus I wasted my time, and money on shipping.
Seasonic will be hearing from me soon, as I attempt to convince them to refund my shipping charges and buy back the unit from me. I'm not a particularly litigious person (ok, not really litigious at all), but it says "silent" right on the box, and that's false advertising. So for others of you with this problem, don't fall for Seasonic's "guarantee".
I think that Seasonic is using a part that is causing problems with an increasingly large number of motherboards, and they're either going to have to fix the problem very soon, or they'll have a tarnished image on their hands.
Good luck to everyone else...

PenDragon - don't forget that many of the ANTEC SU380 PS's are made by Seasonic and they are having the same problems. I agree, ANTEC and Seasonic need to step up and fix the problem, or at least acknowledge it in the first place. ANTEC doesn't even acknowledge the problem, heck they didn't even realize that Seasonic makes a ton of their power supplies. Perhaps a class action lawsuit is in order...
Well, I just received a few ANTEC SU-380's back from ANTEC through the RMA process. Interesting to note is that these supplies are labeled SU380 SF. I don't quite know what the SF designation means, anyone?
I guess we'll see if these buzz, too. If they do then I am going to confer with my attorney regarding initiating a class action lawsuit.

Update
I emailed the Seasonic tech support guy explaining that the new PSU also buzzed, and I pretty much let him know that I was not happy at all. He sent me another one, and a prepaid UPS label for returning the buzzing one. I just installed it 30 minutes ago, and so far, no buzzing at all. I've got my fingers crossed.... I"ll let you guys know if it does start buzzing on me.
Lamster- any new "buzz" from your camp?

To be honest I haven't even had the time to test out these SU-380SF's yet, although I am anxious to see if they do buzz.
So I think we can safely say that there was a problem with the production or the sourcing of parts used for the SU-380 & SS380 PS's. I'll keep you updated as soon as I put one of these new supplies into a case.

Hey guys, sorry for my lack of follow-up- 50 lashes with a wet noodle for me. In my defense, I haven't been getting my thread subscription emails for some reason .
The new power supply that I mentioned in my post on March 30 has been running great. I don't notice any buzz at all. It's a Seasonic S12-380W. I'm with sslamster in that there was probably a bad batch. For those of you also going through this problem, I recommend following up with Seasonic and Antec, rather than just buying a new PSU. With Seasonic at least, they were willing to keep RMA'ing until I got a working unit, and I only got zapped for shipping the first time around.
Good luck!

The buzzing has something to do with the motherboard telling the PSU how many watts it needs, or something like that. My last motherboard, the PSU was dead silent. I put an intel mobo in today and all of a sudden my power supply is freaking out. Kind of annoyed. Fvcking PSU vendors need to get around to fixing coil buzzing in next generation PSUs
dejsti- I was in direct email contact with Seasonic's main support guy, so he took care of the RMA process for me. During the first RMA, I was told to send an email to him, so I got his email address from my Sent Items and then just sent a new email to him. Is that something you can do?
jaldridge- I agree that the motherboard has something to do with the buzzing, considering that the buzzing PSUs didn't buzz on my other stystems.
