ASRock USB 3.0 CARD 2-Port PCI Express Card

The ASRock 2-Port USB 3.0 PCI Express x1 Card is a no-nonsense expansion card designed for desktop users who have run out of USB ports or whose systems lack USB 3.0 connectivity entirely. By occupying a single PCIe x1 slot — the smallest and most commonly available expansion slot on modern motherboards — the card adds two USB 3.0 ports capable of data transfer speeds up to 5Gbps. This is a significant upgrade over USB 2.0's 480Mbps ceiling, making it particularly valuable for users who regularly transfer large files to and from external hard drives, SSDs, or flash drives.

Installation is straightforward: the card slots into any open PCIe x1 (or larger) expansion slot and the rear bracket positions the two USB 3.0 ports at the back of the case for easy access. Both ports are fully backward compatible with USB 2.0 and USB 1.1 devices, so existing peripherals work without issue. For users with older desktops that predate USB 3.0 or for those who simply need more high-speed ports than their motherboard provides, the ASRock USB 3.0 Card offers a cost-effective, low-effort upgrade path.
