Four USB 3.0 ports via PCIe
The RIITOP PCET4U3-NEC adds four USB 3.0 ports to a desktop computer through a PCI Express 1x or larger slot. It delivers up to 5.0 Gbps total bandwidth shared across the four ports. The card uses a Renesas chipset and includes UASP support for faster storage transfers.
Fits a full-height desktop with a free PCIe slot
A vacant PCI Express slot of 1x width or wider is required on the motherboard. The bracket is full-height only, so the card will not install in slim or low-profile chassis. No external power cable is needed because the card draws up to 8 A total, 2 A per port, directly from the PCIe slot.
Passive cooling with self-powered design
The card operates without a fan, relying on case airflow for cooling. On-board power modules and circuit protectors supply stable 5 V current to each port, supporting hot-swapping of USB 3.0, 2.0 and 1.1 devices. Power draw and thermal load are limited to what the PCIe slot provides.
