Are you sure you have a motherboard and not a snake? Please don't power up snakes.

Make sure there's no foreign objects in the CPU power plug and ensure that all connections are fully inserted. Make sure to use the cables that came with the G2 and none of the G1's - although they're EVGA branded, the G1 and G2 are made by different manufacturers.

If you have your old PSU still, try swapping back to see if the issue persists.

e. While you're in there checking it out, make sure your motherboard has all its mounting screws in. They ground the motherboard to the case and may potentially cause electrical funkiness if not installed. They should be snug, but not tight.

From where you've pin-pointed the sound, it seems like it's the VRM on your motherboard that's making the noise (but I can't say for sure). If the CPU itself was making noise then you'd probably be having much bigger problems.

Running with C-States disabled won't harm your components, but it will increase your power bill somewhat as your CPU will be at full voltage all the time. Since it's a desktop, battery life and cooling impacts aren't that much of a concern.
