i ordered a 6 port PCI USB 2 card for my PowerMac G4 MDD it has the 360w PSU. This USB card has 5 external and 1 internal port it also has a Floppy Power connector on it little did i know when i bought it is actually coming from China. So here is the question. Do i need to hook Power to this USB card? I have never seen a USB 2 card with a power connector. What Purpose would a Powered USB 2 card offer over a usual USB Card? I already have a 3 port USB card in this mac which came with it but i need more ports and this USB card does not have a power connector.
