FAQs

Will I need to plug in power to this USB controller card from my power supply?

Yes, it is required to use the included power connector with this card. Additional power is required above what the PCI or PCI Express slot on the motherboard is able to provide. If the power connector is not used with the card, the devices used with the card are not likely to function correctly, and the ports on the card will not be able to output the maximum amount of power USB is capable of.
