I think it's the same thing. For me, it's not just how loud it is, it's how the noise changes depending on the GPU load (I guess). When the FPS is above 200, it sounds like I have a spectrum tape deck that's been sucking down helium gas in my pc.
I've tried a cooler master 1000W M2 and a corsair RM750x and the whine is the same using both power supplies. Having put a bit of thought and effort into making this PC nice and quiet, it's kind of been spoilt a bit by what is the single most expensive component in it.
Since I plugged in the third cable, the noise has come down but is still there a tiny bit. Given that I wear headphones when I game, it's not too much of an issue for me I suppose.
