Description
Product Overview
The LDLrui USB C PCIe card is engineered to give desktop computers a modern edge by adding two high‑speed USB 3.2 Gen 2 Type‑C ports. Each port supports up to 10 Gbps data throughput, which is ideal for transferring large media files, running external SSDs, or connecting high‑resolution monitors that rely on USB‑C video output. The card also supplies up to 15 W (5 V × 3 A) of power per port, enabling fast charging of smartphones, tablets, and other USB‑C powered devices without the need for an additional power brick.
Built on a compact PCIe x4 form factor, the card measures just 4.72 × 3.14 × 0.73 inches and weighs only 3.52 ounces, making it suitable for both full‑size towers and smaller cases. It features a dual‑supply design: primary power is drawn from the PCIe slot, while a supplemental SATA power connector ensures stable operation for power‑hungry peripherals. The card’s low‑profile bracket allows installation in slim cases where space is at a premium.
Compatibility is broad. The card works with Windows, Linux, and macOS operating systems, and it is fully functional in PCIe 2.0 environments as well as newer PCIe 3.0 x4 slots. The ASM3142 controller chip guarantees reliable performance across a range of motherboards, and the card’s firmware is automatically recognized by modern BIOS implementations, eliminating the need for driver installations in most cases.
LDLrui has focused on durability and quality. The card’s PCB is reinforced with a metal shield to reduce electromagnetic interference, and the USB‑C connectors are gold‑plated for improved corrosion resistance and signal integrity. The product has earned a 4.6‑star rating from over 50 verified customers, reflecting its reliability and ease of use.
In addition to the core card, the package includes a low‑profile bracket, mounting screws, a mini screwdriver, and a concise user guide. LDLrui backs the product with a one‑year warranty, 30‑day return policy, and 24/7 technical support, ensuring peace of mind for both hobbyists and professional system builders.
Usage
For gamers, the extra USB‑C ports provide a convenient way to connect high‑performance peripherals such as VR headsets, high‑refresh‑rate monitors, and external graphics enclosures without sacrificing bandwidth. The 10 Gbps speed ensures that data‑intensive applications, like game streaming or rapid asset loading, run smoothly.
Creative professionals benefit from the fast data paths when working with large video files or high‑resolution photography. Connecting an external SSD via USB‑C allows for near‑instantaneous file access, dramatically reducing render times and improving workflow efficiency. The 15 W power delivery also means that devices like external audio interfaces or portable monitors can be powered directly from the card.
In office environments, the card simplifies cable management by consolidating multiple USB‑C devices into a single, high‑speed hub. Users can connect docking stations, fast external storage, and charging cables without cluttering the workstation. The card’s compatibility with older PCs means that legacy systems can be upgraded to meet modern connectivity standards without a full system replacement.
For small form‑factor builds, the low‑profile bracket ensures that the card fits into compact cases where space is limited. Installation requires only a free PCIe slot, and the included screwdriver makes the process straightforward even for first‑time builders.
Overall, the card is suited for anyone who needs reliable, high‑speed USB‑C connectivity—whether for gaming, content creation, data backup, or everyday peripheral use.

FAQ
Will this card work in a PCIe 2.0 slot?
Yes. The card is fully compatible with PCIe 2.0 motherboards. While it can operate at PCIe 3.0 x4 speeds, it will automatically adjust to the bandwidth available in a PCIe 2.0 slot, still providing the full 10 Gbps per port.
Do I need to install drivers for the card?
In most cases, modern operating systems recognize the card automatically and install the necessary drivers. For older versions of Windows or Linux, LDLrui provides a driver package on its website to ensure optimal performance.
Can I use the card to power a USB‑C monitor?
Yes. The 15 W power delivery per port is sufficient for many USB‑C monitors that require up to 15 W. For monitors that need higher power, an additional power source may be required, but the data connection will still function at full speed.
Is the card compatible with macOS?
Absolutely. The card works with macOS 10.13 and later. macOS natively supports USB 3.2 Gen 2, so you will experience the full 10 Gbps bandwidth without additional software.
What is included in the package?
The package contains the PCIe to USB 3.2 Gen 2 card, a low‑profile bracket, mounting screws, a mini screwdriver, and a quick‑start user guide. All items are packaged in a recyclable box.
