Corsair CX750M 750Watts making noises?

I just want to make sure that it will not harm my other computer components, ok my computer specs are

ASUS M5A97 AM3+

AMD FX-4100 Quad Core 95W

x3 120MM fans

x2 Optical Drives

EVGA GTX 760 2GB GDDR5 running with 1x 8pin PCI-E 1x 6PCI-E Power

12GB RAM DDR3 Corsair Vengence

2TB Seagate SATA3 HDD

My only concern is that will it harm or does it sound risky to people for hearing a high pitch sound, it only goes away when I switch my computer to power saver using ASUS EPU, then when you switch it to high performance, it starts that high pitch sound again, like the GPU (Graphics Processing Unit), I know its normal for GPU to buzz, because mine does that to my old one and still works till now! its a EVGA GTX 550 Ti 1GB GDDR5 SC. Do i need to return the PSU or is it normal for this PSU to sq-eek like someone is shooting a tazer gun at my PSU. Im just worried that it might brick my whole Built! and thanks for the help in advance!
