Is the psu faulty or something else

post #1 of 7
Thread Starter 
I can hear coil whine from around my cpu area. Thought it was the h100i which it did make also a buzzing sound so getting that collected today for a refund from amazon. Now today i also put the intel stock cooler on and i still can hear the coil whine. Also one or two month ago plus a few days ago also. when i switched on the psu i heard a pop sound but everything is working. Does that mean its the psu that is causing the problem. I have also taken off the graphics card to be sure its not the card that's making the coil whine sound. And without the card it still makes the coil whine sound. Also the coil whine comes and goes and its not that loud but its very annoying

Unless its very loud coil whine is just anyoing as hell and you cant really do anything about it

You can ask the maker of your PSU if they take it back and have a look at it

If the coil whine is loud they may give you a new PSU

About a week or two ago. Also both my monitors hooked on to my gtx 670 went blank for a few seconds. Not sure if this has anything to do with the psu. Am just thinking if it is a faulty psu. Do you think it will cause any other problems to the other hardware if the psu is faulty. The only thing i can do is send it back to corsair in US which will cost me probably half the price of the psu or more. Or another thing is buy another psu to make sure its not the psu that is causing the coil whine

If its coming from your CPU area, it might be coil whine from the CPU VRM coils. In which case you are s c r e w e d.

You could take the PSU out of the case, move it around and see if the noise moves with it. There's probably enough lead on the PSU cables to do some moving around.

Coil whine is not an indicator of impending PSU doom, though.

I think you might be right about the VRAM the only time i hear the coil whine is when it is at idle. But when playing games and stuff i cant hear it

I think i have solved the problem. The thing is when i connect any kind of usb wifi. To the back of the motherboard. I get the coil whine sound coming from around the cpu area. But if i take off any kind of usb wifi the sound stops. Just don't know why this happens. I have now been using the usb wifi with an usb extension from the front of the case usb ports and there is no coil whine coming so far need to test it today to make sure again that's again
