This PCI Express based 12V Powered USB Card allows you to add three Powered USB (USB PlusPower) ports to any standard form-factor sized computer, using an available PCI Express Slot. Drawing power from either the PCI Express slot or the computer power supply, the powered USB adapter card provides up to 3A of current to each connected device, allowing for up to three Powered USB devices to be installed at the same time. Plus, the PCI Express Powered USB Adapter card can be connected to the corresponding accessory daughter board PUSBADAP (2 Port Low Profile 12V/24V Powered USB Adapter Card), to create two additional Powered USB ports, but does not require a second PCI Express slot.


NOTE: Approximately 100W of spare power is required from the power supply when peripheral devices are connected and running.
