Adds four USB 3.0 ports via a PCIe x1 slot with 5.0 Gbps total bandwidth and per-port 2 A power, no extra power cable required
The ESTONE PCIE24USBA adds four USB 3.0 ports to a desktop through a single PCI Express x1 lane. It uses a NEC chipset to deliver up to 5.0 Gbps total bandwidth for video, audio, photos or files. Each port supplies up to 2 A, giving 8 A combined for high-draw devices. The card fits x1, x4, x8 or x16 slots and does not need an external power cable.
Windows 11, 10, 8.1 and 8 (32-bit and 64-bit) plus Windows Server 2012, 2012 R2, 2016 and 2019 recognise the card without extra steps. For Windows 7, Vista, XP and older releases the supplied mini-CD holds the RENESAS/VLI USB 3.0 driver that must be installed first. The product does not support Mac OS, Linux or GPU passthrough, so builders needing those platforms should look elsewhere.
Under continuous load the 5.0 Gbps ceiling is divided between active ports, so simultaneous heavy copies will run slower than a single-stream burst. On-board circuit protectors and voltage-stabilising capacitors guard against drops during long sessions. The card draws all power from the slot, so the motherboard must supply enough current for the full 8 A rating.

Check Device Manager under Universal Serial Bus controllers; the card should appear as a USB 3.0 Root Hub with SuperSpeed listed, and connected devices will show a 5.0 Gbps link speed in their properties.
The package includes the PCIe expansion card, a driver CD, mounting screws and a user manual; you only need an available PCI Express x1, x4, x8 or x16 slot on your motherboard.
The same card works for both; Windows 11, 10, 8.1 and 8 install the driver automatically, while Windows 7, Vista and XP require the supplied CD driver.
