Single-port USB 3.0 card

The Syba SY-PEX20041 adds one external USB 3.0 port through a PCI Express slot. It suits owners of older desktops that lack native SuperSpeed ports and need a simple upgrade for external drives or peripherals. The card follows the USB 3.0 Rev 1.0 specification and works with PCIe 1.0 and 2.0 systems.

Low thermal and power profile

A single-port controller draws minimal power and produces negligible heat inside the case. No active cooling is fitted, so the card adds no audible noise during normal file transfers or peripheral use. Backward compatibility with USB 2.0 and 1.1 ensures legacy devices function without extra configuration.

Steady throughput on long transfers

The controller sustains the 5.0 Gbps SuperSpeed rate across extended copy operations rather than only in short bursts. Low-speed 1.5 Mbps, full-speed 12 Mbps and high-speed 480 Mbps modes are also maintained without throttling. Driver support is supplied on the included CD for operating systems that require it.

Questions about this item

How do I install the SY-PEX20041 card in my desktop?

Power off the PC, open the case, insert the card into any free PCI Express x1 or larger slot, secure the bracket screw, close the case, boot up, and install the driver from the included CD before connecting devices.

What future maintenance will the SY-PEX20041 require?

No scheduled maintenance is needed; if a driver update becomes necessary, download the latest version from the manufacturer and reinstall, otherwise the card runs passively without user service.

What limits sustained throughput on the SY-PEX20041?

The single USB 3.0 port tops out at 5.0 Gbps and the PCI Express 1.0 or 2.0 lane it occupies caps total bandwidth, so heavy continuous transfers will hit that ceiling first.
