Weird psu electrical buzzing

[the cool guy X_X]

I completed my first build yesterday. Today in the morning I heard a weird electrical buzz from my pc . So I tried to locate the source . Later I found that it was the psu . When I found that I instantly close the pc from the wall socket . After 30 minutes I tried to turn on the pc . It worked but the buzzing sound is still there so I turned it of as fast as possible again . If you have any idea help me . This is my first build and I am 15 years old I don't know much about psu . But I know that the psu could kill all my brand new pc .

These are my parts list : 

ryzen 3 3100

gtx 1660 super gigabyte 3x fans

p450m pro4

g skill ripjaws v 16 gigs 3200 mhz 8×2 kit

Kingston 250 gig ssd

1st player d5 case

and the psu is cougar VTE 600 w 80+ bronze 

please if you have any idea of how to solve the problem please help ...

 

the sound is not loud at all . In fact you can hardly hear it . If you don't have a really good ear it is impossible to hear it . But there is a sound
