Buzzing PSU

My PSU is generating a periodic buzzing noise with varying volume levels. It's intermitent, and I might not hear it for a few days. However, once it starts, I have to shutdown and turn the PSU switch off to make it stop. This isn't a fan vibration, and seems to be a vibration from the transformer. The PSU is supplying good clean power, even with the buzzing.

2 Questions:

1. Do you have suggestions on a way to stop the buzzing from occuring?
2. Is this something you would attempt an RMA for? (it's annoying, but works)

If you're curious, this is an OCZ PSU
 
Is the buzzing caused at random, under load, playing game?

I would RMA it if you still can. Why wait?
 
I think gaming, but I can't be certain. I really haven't isolated a cause yet. I'll play closer attention to it.
 
I believe the insulation between the transformers may have partially failed. Ever heard of "exploding" transformers? Your only suppose to hear such humming noises coming from "massive" transformers, which is normal. RMA at once, not worth sacrificing an expensive rig due to a faulty powersupply.
