See I thought the same and was basically told I'm an idiot for thinking that in another thread...
Then we are all idiots together.

Could be either component, really.
I will say I have had a LOT of trouble with Corsair-branded power supplies and coil whine. I've been through multiple RMAs in some instances, and STILL ended up with a unit that whines when moderate load is placed on it. It's also worth noting that allowing the power supplies to burn-in generally did help eliminate some (or all) of the whine, but it took about a week of normal usage to get to that point.
I've also had coil-whine issues with a GTX 260 and a HD 6970, but most graphics cards have been just fine.
Btw I put in my old 750 Ti and while there definitely is still whining, it's much less noticeable and I do actually have to basically put my ear beside the card to hear it.
Still doesn't rule out PSU whine I guess since power draw is much lower, but it's something.
Yeah, I picked Corsair for that "hybrid" fan feature too... but replacing fan noise with coil whine isn't a great tradeCorsair AX1200i. It's overkill I know, but I chose it specifially for the fanless opertaion below 30% load, and given how efficient these Maxwell cards it has panned out thus far. (or maybe not lol?)
I guess I really lucked out... Maybe some combination of motherboard (intel DX79SI) + psu (Enermax Platimax 850) + cards? Neither of my STRIX cards have whine. I have tried 3dmark11 and all the demo tests - those max the gpus out according to the afterburner monitors on my G13. I also have played Far Cry 3, Wolfenstein TNO, Diablo3 (on 3 screens it actually does work the gpus a bit), and Alien Isolation (which isn't too hard on the system). I'll try some more games this weekend...
Have you tried what I have mentioned about using FurMark? Toggle that furry off?

Michael H from Newegg said:Pros: Card is really impressive for the price.
Cons: Coil whine.......I refuse to drop hundreds of dollars for a noisy product. Especially when I've dropped serious cash on quiet case fans, defeats their purpose.
Other Thoughts: I jumped from Gigabyte GTX 760s in SLI to this card for Oculus Rift development, as at the moment it doesn't support SLI (hope that changes). Its a great card, and my 760s are perfect....but that coil whine. My 760s did not whine. I also tested with my lastlast builds PSU and it whined as well. Internet says this is an issue with several companies. I may wait a few more weeks to see if bad press lights some fires .
Seems like these cards have some real coil whine issues that can't really be blamed on the PSU.
My suspicion is that burning in changes the resonant frequency of the tank circuit that is causing the coil to vibrate. It could be a slight inductance, capacitance or resistance change that moves the resonant frequency outside of the audible range or outside of the coil's resonant frequency thus halting the coil's vibrations. Lots of anecdotal evidence to suggest something is going on along with the altering of the voltages and frequencies being applied to the coils. Sometimes a little hot snot takes care of it but modern coils are now sealed and aside from drilling open the case and pouring in epoxy, burning in and voltage tuning are pretty much the only two things to try. Otherwise, its RMA time.
Captured a short video for anyone who want to be bothered by it...
Turn on annotation & don't mind the fan noise... very low in person.

Here's my Asus Strix 970 video by comparison.

It can be heard clearly even though I've got a noisy stock i7 4790k cooler fan running.
Jesus, these videos.. I don't hear any sound coming from mine, I consider myself lucky.
Wow really? You've tried the FurMark method I've explained before?
