Silverstone SG05-450W squealing noise

I have just put together a build using a Silverstone SG05-450W case/PSU and I have just noticed a squealing sound from the system as soon as it boots into windows. On a warm reboot the noise will stop as soon as the computer leaves Windows 7 and then resumes as soon as I get to the welcome screen. The PSU is a V2.0 which I am told is supposed to fix such issues?

What would be the best way to test before I RMA the PSU?

Full spec:

Silverstone SG05-450W
Intel 3750k
Asus P8Z77-I Deluxe
Samsung Green 8GB DDR3
Crucial M4 256GB SSD
WD Red 2TB HD

I reckon it may be something in the PSU, if you can, unscrew the top and have a look inside..

Can't do so without invalidating the warranty, it's only been used for a matter of hours.

sounds like coil ripple to me, or the ball bearings on the fan aren't great... if it keeps happening, RMA the psu and ask for a replacement

Click link for sound. I separated the PSU from the motherboard with a thick bit of card and the noise is coming from the extra power daughterboard on the motherboard itself so I'm going to have to RMA it

I tried different fans so it definitely wasn't that. It's also an intermittent sound, almost like morse code, rather than a constant bearing noise anyway.
