Enermax 450W power supply EG465P-VE(FMA)

There is a continuous significant humming / burring noise coming from this power supply unit. This is not due to the fans as it is a different type of sound and it stays the same volume when the outside fan is reduced to its lowest rpm. This is an annoying additional sound. Is this suppose to happen?
My old 230W psu was much quieter with only fan noise (no additional humming noise).

My current system load is only about 250-300W.
This would put a max 66% load on the 450W power supply. For this load the power supply specification quotes a noise level of aprox 29dB, but the sound appears significantly louder.

Is this a faulty power supply?

Thanks

Dave

try shaking the power supply to move possible wire, if that doesn't work i would get in contact with sellers and request a replacment, but i had a similar problem when a wire was hitting the fan.
