  • Adds three USB 3.0 ports and Gigabit Ethernet through one PCIe slot
  • USB 3.0 delivers 5 Gbps data transfer for fast peripherals
  • Gigabit Ethernet provides 2 Gbps full-duplex network bandwidth
  • Low-profile bracket included for installation in compact or standard PCs
  • Optional SATA power connector supplies extra current for power-hungry USB devices

Single-slot connectivity upgrade

The StarTech PEXUSB3S3GE adds three USB 3.0 ports and one Gigabit Ethernet jack through a single PCI Express slot. It suits desktop owners who need both extra SuperSpeed connections and a wired network link without occupying two expansion slots.

Steady throughput with optional power

The Renesas µPD720201 controller delivers 5 Gbps per USB port while the Realtek RTL8153 handles 2 Gbps full-duplex Ethernet. A 15-pin SATA power connector is available for devices that draw more current than the slot alone can supply, helping maintain consistent speeds during large transfers.

Check slot profile and OS support

The card ships with a standard-profile bracket and includes a low-profile alternative for compact chassis. Verify that your motherboard has a free PCI Express slot and that your operating system appears in the supported list, which covers Windows XP through 8.1, Server 2008 R2 and 2012, plus Linux kernel 2.6.31 and later.

Questions about this item

How hot does the Renesas µPD720201 controller and Realtek RTL8153 LAN chip run when the card is under full load all day?

The card draws power from the PCIe slot and the optional SATA 15-pin connector; both chips are rated for standard desktop thermals and have no active cooling, so case airflow is the only factor.

What must my motherboard provide so the three USB 3.0 ports and the Gigabit Ethernet jack actually work?

A free PCI Express slot (standard or low-profile) plus a spare SATA power cable if you want the extra current headroom for bus-powered USB devices.

Will the card slow down my older PCIe 2.0 motherboard or conflict with a legacy PCI sound card I want to keep?

It negotiates at PCIe Gen 1 speeds on a 2.0 board and uses a separate interrupt line, so the sound card keeps its own resources without conflict.
