Can the new 21” iMac’s USB power it?

I have checked G-Technology’s website, There is a note:
“** NOTE: G-DRIVE mini is bus powered when attached to a 6 or 9-pin FireWire port. The USB port on some computers may not supply enough power to reliably operate G-DRIVE mini systems larger than 320 GB. An optional power supply is available for use with G-DRIVE mini if your system does not have a FireWire port or your USB port does not provide adequate power.”
I want to ensure that the new 21” iMac’s USB port have enough power to use this drive without using the power cord. I want to use it for Time Machine. I hate power cord, i want less cable on my desktop.

    Not a problem!

    The new iMacs feature USB 3.0, which will provide more-than-enough power for the drive. Because the drive is bus-powered, you will not require an external power source!

  • It SHOULD work, considering you plug it in directly to your iMac, not through a USB hub.
