Overview

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.

Pros & Cons

👍 Pros

  • Adds two USB 3.0 ports without replacing existing ones, expanding your desktop's total connectivity.
  • PCIe x1 interface fits into the smallest available expansion slot, preserving larger slots for other cards.
  • USB 3.0 speeds of up to 5Gbps dramatically improve transfer rates for external drives and peripherals.
  • Simple installation requires only seating the card in an open PCIe x1 slot with no complex configuration.

👎 Cons

  • Only two ports are added, which may not be enough for users with many USB peripherals.
  • Requires an available PCIe x1 slot, which some smaller or fully populated motherboards may lack.
  • The card may need a SATA or Molex power connector for reliable operation, which is not specified in the listing.
  • Limited to USB 3.0 speeds (5Gbps) rather than the faster USB 3.1 or 3.2 standards available on newer cards.
