Is psu clicking noise normal?

[dota2er]

My seasonic gold focus 850 was just installed 2 weeks ago and it is brand new. It was fine until I turn hybrid mode on, the small clicking noise appeared, small but annoying. But when my computer at full load, the clicking noise disappeared. I am not sure if it is covered by other noise or just no more. I did research online, seems many psu have similar problem or even coil whine(Not sure if mine belong to it). So is it normal?
