GEMBIRD UPC-U3 PCI Express USB 3.2 Gen 1 Card, 2x Type-A, SATA Power, ASMedia Chipset

Most budget USB 3.0 add-in cards cut corners with a single port or rely on motherboard headers for power, but the GEMBIRD UPC-U3 delivers two full-speed USB 3.2 Gen 1 ports on a PCIe x1 card with a dedicated SATA power connector, ensuring stable 5 Gbps transfers even when both ports are driving bus-powered external drives. The ASMedia ASM1042A controller is widely supported under Windows and Linux, so you can drop this card into an older desktop and immediately gain modern USB connectivity without hunting for drivers.

Highlights

• Two USB 3.2 Gen 1 Type-A ports with 5 Gbps data rate
• PCI Express x1 interface, compatible with PCIe 2.0 slots
• SATA power connector for reliable power delivery to connected devices
• Backward compatible with USB 2.0 and USB 1.1 devices
• ASMedia ASM1042A chipset with broad OS support
• Hot-swap and plug-and-play capability
• Per-port overcurrent protection

In daily use

Installing the UPC-U3 takes minutes: plug it into an available PCIe x1 slot, connect a SATA power cable from your power supply, and secure the standard-profile bracket. Windows 7 through 11 and most modern Linux distributions will recognize the card automatically. The two Type-A ports are ideal for external SSDs, high-speed flash drives, USB hubs, or even charging smartphones and tablets. Because each port has its own overcurrent protection, a faulty device won’t take down the entire card.
