PCIe x1 3-Port IEEE 1394A FireWire Expansion Card, PCI Express 1394 Controller with 2×6-Pin +1×4-Pin External Ports, Full & Low Profile Brackets for Desktop, DV Camcorder Video Capture & Legacy FireWi

This PCIe x1 IEEE 1394A FireWire expansion card adds 3 external FireWire 400 ports to modern desktops without native FireWire interfaces, solving connection issues for legacy DV camcorders, professional audio gear and FireWire external hard drives.

Equipped with two 6-pin ports that deliver both data and bus power, you can run unpowered FireWire storage and multi-device daisy-chaining directly. The dedicated 4-pin port matches the compact connector on old MiniDV camcorders for direct video footage import without extra adapters.

Comes with two interchangeable metal brackets: standard full-height for regular ATX chassis and low-profile short bracket for slim small-form-factor PCs, covering all mainstream desktop case sizes. Built with industry-certified controller chipset, it follows IEEE 1394 OpenHCI V1.0/V1.1 specifications to guarantee lag-free uncompressed video streaming and stable audio recording workflows.

Support hot-swap FireWire peripherals and simultaneous multi-device operation. Widely used for DV tape digitization, music studio audio interface connection, old photo/video storage backup and industrial scanner data transfer. All gold-plated port contacts reduce signal attenuation and resist oxidation for long-term reliable transmission.

Note: This card only supports 1394A FireWire 400, not backward compatible with 1394B FireWire 800 devices; shut down the PC before plugging/unplugging high-power bus-powered peripherals to avoid signal dropouts.
