❓How does this card compare to the builtin USB 3.1 10G ports on a computer motherboard? Will it be more stable than the native USB 3.0 ports on the PC?

✅ It will be more stable than the motherboard's built-in USB ports because most onboard USB ports are routed through the chipset (Southbridge). This card connects directly to the CPU via a dedicated PCIe slot with an independent USB controller, bypassing the chipset for lower latency and higher efficiency.

❓Can it power external devices? What’s the maximum power output per port?

✅ Yes, it can power external devices when the 15-pin SATA power connector (top-right of the card) is connected. Each port provides a maximum output of 5V 2A.

❓Can this card work without connecting the SATA power cable?

✅ Theoretically, yes if you only need USB data transfer and the connected device has its own power supply, the card can operate without the SATA power cable.

❓Does it require drivers on Windows? Which systems are supported?

✅ It supports plug-and-play (driver-free) operation on Windows 10 and Windows 11.

For Linux, it’s plug-and-play on kernel versions 2.6.31 and above.

❓What’s the bandwidth per port?

✅ Each port delivers 10Gbps bandwidth.

❓Is this card compatible with industrial cameras? Will it provide stable performance?

✅ PCIe USB cards offer greater stability than motherboard USB ports, making them ideal for high-speed, stability-dependent devices like industrial cameras.
