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.

Questions about this item

What bandwidth does the PCIe x1 link provide for the four USB 3.0 ports?

The card uses a single PCIe x1 connection, so all four USB 3.0 ports share that one lane's throughput.

What are the card's dimensions and weight for case clearance?

The board measures approximately 120 x 55 x 75 mm and weighs about 70 g.

How is the card powered and what is the common installation mistake?

It draws power directly from the PCIe slot with no extra cable; the mistake is forgetting to seat the card fully so the slot powers it.
