I have the coil whine on my phone charger too lol. If I wasn't able to hear it while wearing headphones and playing at the same time I assume it's ok. Thank you guys for all the quick feedback.
Today I installed my new Corsair CX650M. I played games for like 4 hours and when I took off my headphones I noticed a veeeeery quiet high pitched sound. It's not annoying but I know it is there. Is it normal?
