I just bought a new CX750M to replace my old CX430, and as the CX430 had gave me no problems in the past year or so I owned it, I thought I might as well go with Corsair again. I just wanted a new PSU as I am looking to buy a GTX 970 in the future and a 430W PSU wont cut it. But after installing the new PSU, I heard a high pitched whine coming from the PC when it was under load, so I decided to run OCCD over night on power supply, and this fixed the coil whine problem. But now the PSU has decided to make a horrible buzzing sound under load, a sound which it didnt make before. It makes the sound when under gaming, if in the world of tanks garage, for example, it is quite loud, but when in the game itself, you can barely hear it. Also idle, you cannot hear it at all. I have ran many different stress tests where there is not noise from the PSU, only a slight hum which I would say was normal. I don't know what the problem is. Would it be the fan? Here are my PC specs anyway:
I5 4690K @ 4.3GHz (with Cooler Master Hyper 212 Evo)
8GB of corsair XMS3 RAM
Asus H81L-Plus Mini-ITX motherboard
MSI GTX 760 OC edition @ stock
The new PSU
I have tested and it is not the GPU or CPU fans.
