Liitäntäkortti DeLOCK 89325

The DeLOCK 89325 is an internal interface card that expands a desktop PC with four external USB 3.0‑A ports via a PCIe slot. It uses a PCI Express host interface and delivers USB 3.2 Gen 1 (3.1 Gen 1) connectivity with data transfer rates up to 5 Gbit/s. The card is built around a Renesas uPD720202 chipset and is compatible with a range of Windows operating systems. The unit has a green and silver design and provides additional external USB ports for connecting devices such as docking stations, card readers, hubs and external enclosures.

Advantages

The card provides four independent USB Host Controllers while occupying a single PCIe lane, enabling up to 5 Gbit/s per connection under supported conditions. Its Renesas uPD720202 chipset ensures compatibility with common USB 3.x devices and stable transfer performance. Being an internal PCIe solution, it offers a neat way to add external USB ports without using front-panel headers or external adapters.

Suitable for

• Expanding external USB connectivity on desktop PCs
• Connecting USB docking stations and hubs
• Attaching card readers and external storage enclosures
• Systems requiring additional USB 3.0‑A ports

• Number of external ports: 4 × USB Type‑A (USB 3.0)
• Chipset: Renesas uPD720202
• Form factor: internal PCIe add‑in card
• Product colour: Green, Silver

How to use

Install the card into an available PCI Express slot on the motherboard, secure it in the chassis and connect any required power or system cables according to the computer manufacturer’s instructions. After installation, boot the system and install drivers if the operating system does not automatically recognise the device. Once drivers are installed, connect USB devices to the external USB 3.0‑A ports for data transfer and power as supported by the connected devices.

Recommendations

For optimal performance, connect high‑speed devices directly to the card’s USB 3.0 ports and ensure the host system supports USB 3.x speeds. Install the latest drivers from the chipset or motherboard vendor when necessary and avoid overloading a single port with devices that exceed power or bandwidth limits.
