Four-port USB 3.0 expansion

This Sony Mobile JUP40811S1 card adds four USB 3.0 ports through a single PCIe slot. It suits desktop users who need more high-speed connections for external drives or peripherals. The quad-core controller manages traffic across all ports. The card is new and weighs 0.22 units.

Single-slot PCIe installation

The card occupies one PCIe slot and provides four Type-A ports at the bracket. No extra internal headers or cables are required for the basic four-port layout. This keeps the rear I/O tidy and leaves other slots free for graphics or storage cards. Driver support follows the host operating system.

Sustained multi-port throughput

Under continuous load the quad-core architecture balances bandwidth across active ports so one heavy transfer does not starve the others. Thermal output remains low because the design uses no active cooling. The card maintains link stability during long backup or imaging sessions. First listed by the manufacturer in 2019.
