Hello all,

I have recently bought a Corsair RMx 750 power supply and then i bought gtx 1070 Asus dual 4 days ago. However today i noticed a buzzing sound coming from the back of the power supply (outside the case). Its there even when the PC is off but the PSU is on but once i turn on the PC the noise gets louder and even more louder under load. Should i be worried about?. It should be noted in every scenario the PSU fan is never on.

I will appreciate your help.

Thank you
