Does it buzz all the time or only when stressing the 970? They are notorious for coil whine and it should just like what you described. I have a Corsair 550D silent case and I can only barely hear it, but take the side panel off and its annoying.
It's all the time.

It's stupid funny but if I turn on my Brookstone desktop fan, that pretty much takes my mind off the buzz altogether. Warm weather to the rescue!  retard

I did a headset mic test tonight, and it certainly seemed like the slight buzzing's there when the mic's next to the PSU. When I moved it down towards the case bottom and video card, it was simply some normal fan noise which doesn't really bother me. Now at least I have a recording of it for posterity/proof.  icon_smile

I am just favoring keeping it at this point. And when when I'm up to tackling it, I'll probably try a PSU replacement -- I'm fairly confident that's all I'd need to do. I'm eyeing now maybe something like a 750W, still probably that Corsair RM line. I suspect it's just some coil whine or capacitator whine in the Delta PSU, top notch OEM power supply or not. There's relatively few PSU connectors to worry about it in the case, so it should be pretty straightforward if/when I do it.

I did find this thread interesting/comforting/worrying in that so many people complain about weird PSU noises:

Noisy PSU? Read this first!
http://forum.corsair.com/v3/showthread.php?t=85166
*I tried the op's various Bios tweaks but had no effect. I don't think my buzz is even in the ballpark of some of the complaints there. Some complain about a buzzing sound driving them insane, others say they're getting tinnitus from it.  icon_razz

This example's pretty fun (Corsair deemed it defective and sent him a replacement PSU):

*fwiw, it's not the Corsair model I'm considering.

My Delta? A minor annoyance.  icon_smile My only problem right now is my head. The stuff I really want to play because they push this system (Shadows of Mordor, Ryse of Rome) are giving me motion sickness fits for some reason. So great, I finally have a powerful gaming PC but no real burning desire to play anything at the moment. At least I'll be ready when I do.  icon_smile

So I went ahead and kept it. It's fast, runs cool, has been bulletproof in pretty much every game I've run on it so far. I think that's what's important.  icon_smile

While now I'm thinking maybe the annoying sound was just GTX 970 coil whine afterall (and really, when I'm gaming, I don't notice anything, so I'll live), I did go ahead and replace the 500W Delta power supply. It's marketed as "Silence defined," so it seemed made for me, right?  icon_smile Of course now essentially I'm flushing away the Antec system warranty. Maybe I'll regret it, but I've never gotten warranty service done on store-bought PCs in 23 years, and generally have been upgrading them (more often video cards, hard drives etc.) soon after getting them, over that time.

After some research and remembering my good experience with an Antech PSU in 2007 (only previous experience doing a replacement), I went with the Antech Edge 750:
http://store.antec.com/edge-series/edge-750.html#


*While it has these cool "anti-vibration" rubber gaskets (red and black colors included), I had to skip it -- just not quite enough room (as the Antec manual warned). The PSU has the same slot dimension as the 500W Delta, just a bit longer. The case has a little side lip to support the PSU so it's not "dangling by the mounting screws."  disgust


As weird as the drive bracket may be, having such a roomy case and small motherboard actually made the PSU removal and installation relatively easy. I won't call it a "snap," but I did it Sunday afternoon and really wasn't anything scary.  icon_smile Just been 8 years since I've done it before.


In place.


No, I won't get the Tidy Cable Routing of the Year Award. icon_redface I may eventually try to tidy it up a bit; mostly I just wanted to keep the cables away from the fans. As does the Corsair I was considering, the Antec uses flat black modular cables rather than round/cylindrical cables. The GPU cable had dual six-pin connectors on one cable, and the SATA cable had three connectors. So it's not so much I have too many cables, I just didn't have ties to tidy up the spaghetti.  icon_smile

Replacing the PSU was pretty satisfying, whether it was really necessary or not. Everything booted up and worked fine afterwards. I think maybe next time, whenever that is, I'll finally Build My Own. I guess I've been most intimidated by motherboard-installation, and the thermal paste that was required (maybe still is) for CPU installation, and the PSU. It doesn't look like the latest CPUs requiring messing with paste (or maybe they still do), and certainly a motherboard like this one essentially just screws in with 4 screws. And of course the PSU is not brain surgery. I did find it useful to stick Post-It notes labeling some of the cables on the old PSU before I removed it.

You made no comment on any improvement in the noise problem...

Oh... any electrical device can potentially generate whine... sometimes you have to take steps to muffle it... I've seen psu's where they had so much silicone goop slathered in there you could  have used it to remake 'The Blob'... obviously delta didn't go to too much trouble on your particular model. Doesn't make it a shabby psu... but it's interesting that Asus went with that as an option. (as opposed to something a little more 'refined'.

Your Edge 750's OEM is Seasonic, which also has a stellar rep' for build quality.
