I had to use a powered hub with one of them, to get sufficient power. The powered hub was used for the 'extra' USB connector on the Y cable.

Depends on how your motherboard is wired, but you should always get the most power you are going to get out of the USB ports on the rear of the case, since these are built into the motherboard. Different PC manufacturers may scrimp here.

You can see USB current draw for connected devices in Device Manager. There is a finite amount of current supplied.
