DeLOCK PCI Express x4 Card 2 x USB 5 Gbps Type-A 2 x internal USB

The DeLOCK PCI Express x4 Card adds two external USB 5 Gbps Type-A ports and two internal USB 5 Gbps Type-A ports to a PC. It uses a PCIe x4 interface and provides a maximum transfer rate of 5 Gbit/s per channel, enabling connection of USB flash drives, card readers, external enclosures and other USB devices in systems where additional ports are required.

Advantages

The card implements a dual-channel design with two dedicated 5 Gbit/s channels, each servicing two USB ports. By using separate host controller chipsets for each channel, it reduces bandwidth contention compared with single-bus PCIe cards and improves aggregate throughput. The board features on-board 5 V DC power management and therefore does not require an extra external power supply. It is compatible with PCIe x4 slots and is suitable for low-profile system installations.

Key specifications

How to use

Install the card into an available PCIe x4 (or larger) slot on the motherboard, secure it with the bracket screw and connect internal USB headers to the system front panel or internal devices as needed. After powering on the PC, install any required drivers provided by the operating system or manufacturer to enable full USB 3.2 Gen 1 functionality. Connect external USB devices to the two Type-A ports for immediate use.

Recommendations

For optimal performance, connect high-bandwidth devices across the two separate channels rather than concentrating multiple heavy-transfer devices on the same channel. Ensure the host system has an available PCIe x4 slot and that the operating system supports the card drivers.
