PSU making odd noises

Hi,

So I bought the motherboard and CPU of my computer second hand, then bought a new HIS 7850 (even worse than reference cooler)
Now, I never noticed whine or grinding noises from my PSU before adding the 7850 (had a 5770 beforehand)
I bought a TX-750M and after a while that developed odd grinding noises (sounds like a hard drive) when doing anything like moving your mouse or scrolling through a web page.
I then got it replaced by the retailer with a newer model with a zero rpm fan mode.
So far the new PSU doesn't give nearly the amount whine or grind that the previous one did, but it's getting worse. I disabled C1E and EIST and it's better again, but it's still not silent. I can quite obviously hear it over the rest of my fans.

Question is, do you think it's the bargain basement GPU, second hand OEM motherboard or the mighty Corsair's PSU ?

Thanks in advance,
Nick
 
I wouldnt go calling a 7850 a bargain basement card, however I have a TX750M, I think its the first version without zero fan mode and its the noisest thing in my system, with all fans off my psu is still running full speed, even at idle load. Its not making any other noises while moving the mouse around on screen, I know the noise your talking about and I have had it on older machines, way before I was clued up on any of this.

I would think its down to the harddrive, its the only thing that could make that mechanical noise

The card I bought is, as in there looks to be minimal VRM circuitry and the smallest fan they could find without making the thing blow up. I really should have gone for a more reputable brand like MSI

It's definitely not the harddrive, and it sounds like there's a large fly stuck in the psu trying to fly every 3 seconds or so whilst gaming. I'm reluctant to send it back just to have the same problem arise again ...
 
Loading up furmark makes the PSU go mad
Loading up prime95 at the same time makes the psu fan turn on and all noises stop

Really don't know what's going on...
 
Right, I watched the PSU as I ran furmark and it looks like it's the fan trying to turn that's making the noise. There is a small amount of coil whine but it's not noticable
The noise is in sync with the fan turning a little bit and turning back
