I hear a low frequency, but high pitch sound coming from my PSU when the power cord is connected, all this while my Xbox is turned off.

Just a lil' FYI: Frequency = Pitch. So you can't have a low frequency and a high pitch at the same time unles there are two tones or sounds.
It sounds like you have a high frequency, low volume sound? (The pitch is high, sharp, or shrill while not being real loud.)

The powercord I received from M$ didn't look any different from the one it was replacing, but I went ahead and replaced it. It felt different as in a different kind of plastic covering.
