EN-Labs PCIe to 2-port USB 3.0 expansion card NEC uPD720202 Molex

PCIe x1 card adds two USB 3.0 ports

This EN-Labs expansion card fits any desktop PCI Express x1, x4, x8 or x16 slot and provides two external USB 3.0 Type-A ports driven by the NEC uPD720202 controller. A low-profile bracket is included for small-form-factor cases. The card draws auxiliary power from a Molex 4-pin connector to ensure stable operation under load. A driver CD supports Windows XP through Windows 8 and macOS 10.8 and later.

Builders adding front-panel or rear USB 3.0

Ideal for system integrators and enthusiasts who need extra SuperSpeed ports on a motherboard that lacks them, especially when the board has a free PCIe slot but no internal USB 3.0 header. Not suited for users who require internal USB 3.0 headers for case front-panel connectors, nor for builds without a spare Molex power lead from the PSU. The x1 edge connector works in larger slots, so slot width is rarely a constraint.

NEC uPD720202 controller delivers 5 Gbps per port

The single decisive specification is the NEC uPD720202 chipset, which implements the USB 3.0 SuperSpeed specification at 5 Gbit/s and is backward compatible with USB 2.0, 1.1 and 1.0. It complies with PCI Express 2.0 and xHCI 1.0, so each port can sustain the full 5 Gbps rate when connected to a compatible device. If your workload demands higher throughput or a different controller feature set, this card will not meet that need.
