Hello, everyone, I've been lurking for a while now, but this is my first post -- I just completed my first PC build this evening, a very inexpensive mini-ITX box, and everything went very well with a single exception:
The machine gives off a high-pitched warble from the moment I turn it on to the moment I turn it off. I can hear it clearly from eight feet away, over the resonance and fans of every other electronic device in the room (and I own a few). It's annoying, and my cats are convinced there's something tasty living inside the case.
After some Internet research I suspected coil whine from my PSU, so I disconnected all the internal power cables and plugged in the power supply to give it a listen. I could only hear the noise when I put my ear down to the PSU vent, but it was still there.
So here's my question: my components have pretty minimal draw, but it's only a 250W supply. Could I be taxing it? Is it worth calling in an RMA to Rosewill for an equally cheap (but free!) replacement, or should I just upgrade to more watts and a better brand? Estimating power supply requirements is one thing I still haven't been able to wrap my brain around.
My specs follow:
Rosewill RS-MI-01 case with included 250W PSU (model #AL8250SFX; manufactured by Apex?)
ASRock AD2700B-ITX Intel NM10 Mini ITX Motherboard with included Intel Atom D2700 processor (2.13GHz, dual core)
2x2GB Samsung DDR3 1066/800 RAM
OCZ Vertex Plus R2 60GB SSD
...and that's it. Not a whole lot of moving parts.
Any advice you can provide is appreciated!

Thank you for the advice -- I will remember it next time!
