Should I be worried about my new power supply?

I recently bought a new power supply for my PC (Corsair TX650), because of my new graphics card that required more power. I installed it a few days ago and I noticed there is an intermitent, small and faint, electrical type noise coming from the PSU every now and then. It's not louder than the rest of the normal PC sounds, but if you pay attention to it you can hear it.

Also, when gaming or using a gpu demanding application, the PSU starts emitting a high pitch sound that slowly faints during the first minutes of usage. It is not very loud either, but it is hearable.

Guys is this something I should be worried about or am I just really paranoid? And what are the usual symptoms that indicate a faulty PSU?

I did read in the Corsair forums that the PSU is not "soundless", so that's why I need to know how to tell whether it's something I should be worried about.

Hi - appears to be what is referred to as coil whine. A small % can happen even in high quality units.
Def contact Corsair for RMA. Corsair doesn't mfg these, so most likely you will recieve a new unit rather
than them repairing & returning.

I heard a few examples of a coil whine on the internet and it doesn't seem like it. Also the problem is that I live in Ecuador and got the PSU from a distributor, I don't know how to contact Corsair here. I went to their forums and asked the same question yesterday and I still don't have any answer.

Hi again - even if it isn't coil whine, (although the high pitched sound eems like coil whine) a new Corsair TX shouldn't be making the sounds you describe.
Contact the distributor, they should be able to assist you in contacting Corsair or even help you themselves.

Corsair has a good reputation of standing behind their products.

Ok I'll do that, by the way, is this coil whine thing dangerous, like, should I not use my PC until I get help?

Hi again - No, coil whine is annoying, but not dangerous. However, I don't know the cause of the other sounds you describe, and that could be something to worry about.

However, the TX series PSU's have plenty of built in protection features, so if the PSU overheats or
malfunctions it'll shut itself down to prevent damage to your other components.
