Grwibeou PCIe x1 to 4 Port USB 3.0 Expansion Card

Four USB 3.0 ports from a single x1 slot

This PCIe x1 to four-port USB 3.0 expansion card adds external connectivity to desktops that lack enough native ports. It suits builders expanding I/O for peripherals, external drives or mining rigs needing multiple riser connections. The card draws power directly from the slot, so no auxiliary cable is required.

Gold-plated connectors and six status LEDs

The board measures 120 by 55 by 75 mm and weighs about 70 g, plugging straight into the motherboard without an extender cable. Gold-plated USB connectors reduce interface interference, while six onboard LEDs flash at boot to confirm link status. An onboard BIOS chip improves motherboard and graphics-card compatibility and lowers power draw.

Replaces USB 2.0 headers or single-port add-in cards

The upgrade is worthwhile when a system needs four simultaneous 3.0 connections but has only a x1 slot free. Windows 10 recognises up to eight graphics cards and Windows 7 up to six, so larger GPU arrays require Linux. Buyers who need more than four USB ports or internal headers should look elsewhere.
