Four USB 3.0 ports on a PCIe x1 card

This RIITOP expansion card adds four USB 3.0 ports to a desktop computer through a single PCI Express x1 slot. It uses a Renesas UPD720201 host controller to deliver 5 Gbps bandwidth per port. The card fits x1, x4, x8 or x16 slots and ships with a standard bracket for PCs, servers, workstations or NAS units. Each port supplies up to 2 A for power-hungry peripherals.

No external power connector required

The card draws all power from the PCIe slot itself, so no extra cables or adapters are needed. Total available current is 8 A across the four ports, enough for multiple high-draw devices at once. Windows 10 and 11 work driver-free, while Windows XP, Vista, 7, 8.1 and Server 2003, 2008, 2012, 2016, 2019, 2022 may need the included CD driver. Most Linux kernels also support plug-and-play operation.

Not for macOS or internal header connections

macOS is not supported at all, so Mac builders should look elsewhere. The card provides only rear-facing Type-A ports; there are no internal USB headers for front-panel or additional internal devices. Bandwidth is shared across the single PCIe x1 link, so sustained transfers on all four ports simultaneously will be limited by that link.
