The StarTech PEXUSB3S3GE is an expansion card that adds USB connectivity and Gigabit Ethernet to a desktop computer through a single PCI Express slot. It features three USB 3.2 Gen 1 ports and one RJ45 port. The card supports data transfer speeds of up to 5 Gbit/s, making it suitable for external storage and high-bandwidth peripherals. Powered by Renesas μPD720201 and Realtek RTL8153B chipsets, it manages both connection types independently. This card offers a more stable alternative to external USB hubs and wireless network adapters.
The card features a dual-profile design suitable for both full-height and low-profile computer cases. LEDs integrated into the RJ45 port indicate link and activity status. While drivers are provided for legacy systems, most modern setups will detect the card automatically. It is compatible with Windows versions from XP to 11, as well as Linux kernels from 2.6.31 onwards. The PCB features a metallic red finish.
Key Features:- UASP (USB Attached SCSI Protocol) – improves data transfer efficiency when used with compatible external storage.
- 10/100/1000 Mbps auto-negotiation – automatically adjusts network speed to match the connected router or switch.
- Backward compatible with USB 2.0 and 1.1 – supports the use of legacy peripherals alongside newer hardware.
- Dimensions: 18 x 77 x 120 mm – standard sizing for most desktop chassis.
- Weight: 60 g – lightweight design that reduces physical strain on the motherboard expansion slot.
- Windows Server support – compatible with editions from 2008 R2 to 2025.
