EVGA Supernova 750 G2 Question

I recently just received my EVGA Supernova 750 G2 power supply, and followed the instructions for testing, as per the users manual, and I noticed a high pitch sound. I believe its generally considered a "coil whine"... well I contacted EVGA Tech Support they RMA'd it upon me calling and saying high pitch whine, without any further questions comments or statements.

Anyway, my question is, can I still use this PSU, and will it be fine, while I wait for the replacement? Or should I just avoid using it overall?
Coil whine is not an indicator of a defective unit. All power supplies produce coil whine. Generally it is out of the range of human hearing, and the range that is in human hearing is usually inaudible, although this does vary depending on people and power supplies, and even other hardware used in the computer. You just got that magic combination of components that did produce audible coil whine, but again, it is in no way an indicator of a defective unit. It's an annoyance, simple as that.
I appreciate the information, I wish the technician would have told me that. Since I was trYing to simply just get an answer... lol

I greatly appreciate the reply, thank you!
