Adds four USB 3.0 ports at 5.0 Gbps through a PCIe 2.0 x1 slot with 8 A total power and Windows 7 through 11 support
This ESTONE expansion card adds four USB 3.0 ports to a desktop through a single PCI Express x1 slot. It uses a NEC chipset to deliver up to 5.0 Gbps total bandwidth for video, audio, photos and files. The card fits PCIe x1, x4, x8 or x16 slots and supports Windows 7 through 11, plus Windows Server 2012 to 2019.
A mini-CD supplies the RENESAS/VLI driver required for Windows 7, XP, Vista and older systems, while Windows 10 and 11 work plug-and-play. The card draws all power from the PCIe slot itself, providing up to 2 A per port and 8 A total without any extra cables or internal wiring.
The board measures 4.92 by 4.06 by 1.06 inches and includes a low-profile bracket plus mounting screws for standard or slim cases. Four external Type-A ports face the rear panel, giving immediate access for webcams, hubs, keyboards, smartphones, capture devices or KVM switches.

The card uses built-in power converters and an advanced NEC chipset with no user-serviceable parts, so no scheduled maintenance or component replacement is required.
Yes, the single PCIe 2.0 x1 lane provides up to 5.0 Gbps of total bandwidth shared across all four USB 3.0 ports.
The passively cooled design has no fan, so it adds no audible noise; heat output is low enough that no extra case airflow is needed.
