I have an Corsair CX 750M PSU which is making coil whine when my system is idling.
This is my 3rd Corsair PSU that does it so I'm thinking about switching to another brand.
Before I go through with the switch, I would like to exclude that the problem is somewhere else then the PSU and when it's the 3rd PSU to do this, it get's me thinking.
I've done some troubleshooting to exclude power cables, wall outlets and extenders.
Tested 2 different outlets both with 2 different power cables directly connected and with 2 different extenders.
I even changed my motherboard as I thought that could be the reason, but the coil whine is still there.
Is there anything else I can try before I switch the PSU again?
If I switch the PSU again, I wont select a Corsair because of this experience with the coil whine.
I'm looking at the OCZ Fatality 750M which has received high scores in the reviews I've read but am open to suggestions.
My price limit is between the price of the Corsair CX 750M and the OCZ Fatality 750M and I would like to stick to a modular PSU.
Thanks in advance.
