Product information

Description

The StarTech.com PEXUSB3S42 4-Port PCI Express USB 3.0 Card adds four USB 3.0 (USB 3.2 Gen 1) ports to a PCIe x4-enabled desktop, using two dedicated 5 Gbps channels implemented by dual host controller chipsets. This architecture provides improved throughput compared to single-bus USB 3.0 cards, offers backward compatibility with USB 2.0/1.1 devices, and ships with both full-height and low-profile brackets for installation in different system form factors.

Advantages

The dual-chipset design dedicates up to 5 Gbps per channel (two ports per channel), reducing bandwidth contention when multiple devices are connected. The card supports UASP (USB Attached SCSI Protocol) to accelerate transfers when used with a UASP-capable enclosure and compatible OS, achieving significantly higher read/write performance and lower CPU utilization compared with traditional USB BOT. An optional SATA or LP4 power connector supplies up to 900 mA per USB 3.0 port for bus-powered devices and supports USB Battery Charging 1.2 (Apple Mode) for faster charging of compatible Apple devices.

Suitable for

Adding multiple USB 3.0 ports to a desktop with an available PCIe x4 (or higher) slot
High-speed external storage and SSD enclosures that benefit from UASP
Systems requiring additional powered USB ports for bus-powered devices

Key specifications

Model: PEXUSB3S42
Interface: PCIe (x4 compatible)
Output: 4 × USB 3.2 Gen 1 (USB 3.0) ports
Bandwidth: Two dedicated 5 Gbps channels (up to 10 Gbps aggregated)
Chipset: 2 × Renesas/NEC µPD720202
Power: Optional SATA or LP4 connector; up to 900 mA per USB 3.0 port
Backward compatibility: USB 2.0 / 1.1
Form factor: Full-height with included low-profile bracket
Certifications: CE, FCC
Weight: 0.09 kg

How to use

Install the card into an available PCIe x4 (or x8/x16) slot on a powered-off desktop, secure the bracket, and attach the included low-profile bracket if installing in a small form-factor case. Optionally connect the system power supply to the card via the SATA or LP4 power connector when using high-power USB devices. After powering on the system, install any required drivers or allow the operating system to load built-in drivers. For best performance with external storage, use a UASP-capable enclosure and an operating system that supports UASP (for example Windows 8/8.1, Server 2012, or Linux kernel 2.6.37+).

Usage recommendations

To achieve the fastest possible transfer rates and reduced CPU load, pair the PEXUSB3S42 with a UASP-enabled enclosure and ensure your OS provides UASP support. Use the optional power connector when connecting bus-powered high-current devices, and verify cable lengths and device compatibility for optimal performance.
