Having a strange sound come from the brand-new PSU on my build.

PSU: Corsair CX600 Builder
MoBo: AsRock 970 Pro3 R2.0
GPU: HD7770 2GB

The sound does not start resonating until about 2-3 minutes into boot (from cold boot). If I turn off, and turn right back on, the sound is there from the start.

I'm assuming it's the fan?

NOTE - Put the volume up on video. It's a very low sound, but you'll clearly hear it.

Thank you so much :)
