Two-port USB 3.0 add-in card

The Syba SY-PEX20045 adds two SuperSpeed USB 3.0 ports to a desktop PC through a single-lane PCI Express 2.0 x1 slot. It uses the NEC uPD720200 controller to deliver up to 5.0 Gbps signalling per port. The card targets users who need faster external storage or peripheral connections on systems lacking native USB 3.0 headers.

Driver CD and manual included

A driver disc and printed manual ship in the box, letting administrators install the controller on Windows XP, Vista or 7 in both 32-bit and 64-bit editions without downloading files. The bundled media covers legacy operating systems that may not include the NEC uPD720200 driver in-box, reducing setup friction on older workstations.

Two ports at 5.0 Gbps each

Each port supports the USB 3.0 5.0 Gbps rate, while the PCIe 2.0 x1 link caps aggregate throughput at 4.8 Gbps, so simultaneous heavy transfers on both ports will share that bandwidth. The card suits external hard drives, flash drives or docks, but it cannot serve more than two devices or exceed the host slot’s single-lane ceiling.

Questions sur cet article

Will the NEC uPD720200 chipset on the SY-PEX20045 need a firmware update or driver reinstall after a major Windows upgrade?

The card relies on the NEC uPD720200 chipset and ships with a driver CD for Windows 7, Vista and XP; reinstall the supplied driver after any OS upgrade to maintain full USB 3.0 operation.

Does the single-lane PCI Express 2.0 x1 link limit sustained throughput on the SY-PEX20045 before the USB 3.0 ports do?

Yes, the PCIe 2.0 x1 interface tops out at 4.8 Gbps, which is below the USB 3.0 5.0 Gbps specification, so the bus becomes the bottleneck during continuous high-speed transfers.

How much heat or extra power draw should I expect from the SY-PEX20045 when both USB 3.0 ports run all day?

The card draws power solely from the PCIe slot and has no active cooling; under sustained dual-port load it stays within standard slot limits and adds negligible heat inside the case.
