Hi guys

There is a strange sound coming from my new power supply, the Antec VPF 450w. I'm not sure what this rattling sound is. Mind you, this is the first time I've had a quiet pc so I'm not sure if this sound is 'normal' fan noise or a defect. Just to be sure I unplugged my stock cpu cooler and rear exhaust fan. They case is closed and I held my phone aprox 1-10 mm from the side of the psu.

What is this sound?

(Sound starts when the computer is turned on and lasts the whole video. It's a kind of 'rattle'.)
