That's right at 10 watts. If the power supply is 80% efficient you are putting in 12.5 watts to get the 10. I suspect that is a bit more than the 5V switcher on the net5500 board was designed to supply on a 24/7 basis. A better solution power wise might be to run the single usb port on the net5500 to an external powered hub. As long as you have power to the external supply they shouldn't consume any power from the computer. The obvious problem with this solution is bandwidth. One port takes you down to either 12 or 480 Mb/sec. If you *really* need 4 x 480 Mb/ s you may need something with more cpu than the net5500 ...
