The computer power supply isn't the problem. The power available from a USB 
port varies based on a number of factors. You can read more about the power 
available from USB ports at http://en.wikipedia.org/wiki/Usb#Powered_USB.
You can have anywhere from 100mA to 900mA from a USB port. I was quite 
amazed when I discovered the very small, external, 500GB hard drive that my 
dad had asked me to get for him is fully powered from the USB port only. It 
doesn't need any external power.
