PCIe to USB Expansion Card

1. 4 Port USB 3.0 PCIe X1 Adapter Card: Add 4 x USB-A ports to PC via PCI-Express x1 slot. Then your PC can access 4 x USB-A devices at the same time, such as Keyboard, Mice, Speakers, KVM switch, etc
2. Work with High Power Consumption USB 3.0 devices: Each port can provide 5A2A load capacity, so your PC can access 4 x High Power Consumption USB 3.0 devices at the same time, such as indusrial cameras, VR-Systems, USB 3.0 NVME enclosures. (Note: Not support fast charging, only support 5V/0.5A charging at max)
3. 4 x USB-A 3.0 Port shares PCIe X1 Bandwidth: For PCIe 3.0 X1 slot, 4 x USB-A ports share 8Gbps bandwidth; for PCIe 2.0 X1 slot, 4 x USB-A ports share 4Gbps bandwidth.
4. Built in Self-Powered Technology: Powerd by PCI-Express 12V power supply, no need extra power supply
5. OS Compatibility: Plug-and-play in Windows/Linux (Note: Not support Mac OS);
6. Installation: PCI-Express X1 slot installation

What is Expansion Card Self-Powered Technology?

Self-Powered Technology is a new solution to add more power supply on USB 3.0 expansion cards. The old version PCI Express USB 3.0 cards need to plug power cables from Desktop PC's power supply unit. Even added on additional power, sometime it still lacks power when running few high power-consuming devices simultaneously such as USB HDD/SSD enclosures and USB NVME enclosures. PCI Express slot can provide 75W max power almost 12V/6.25A for PCIE devices. Expansion Card add 4X voltage transformer on USB 3.0 card will pick up 12V/3.5A power and convert to 5V/8A 40W. Each USB 3.0 port will get 5V/2A 10W max power supply for USB 3.0 devices. Most of the high-power consumption devices just need 4~8W which means this USB 3.0 expansion card can light up 4X high power-consumption devices simultaneously.

Expansion Card built 4X electronic safty fuse, 4X voltage stable inductance and 4X voltage stable capacitors on the board, will protect users' data and USB 3.0 devices. Never burn USB 3.0 device and never lost data. Add 4-Ports superspeed 5Gbps max USB 3.0 expansion card on Desktop PCs. Enjoy more stable, superspeed and safe USB 3.0 connection with Expansion Card.

Product Advantage:

1. 1. 4X added-on vertical USB-A USB 3.0 ports with 5Gbps total bandwidth USB expansion card will not occupy Motherboard USB 3.0 Main Lane Speed, it is added-on bandwidth by PCIE X1 Main Lane.
2. 2. Bluilt in Expansion Card Self-Powered Technology, no need to plug any power cable from Desktop PC's power supply unit. Provide sufficient power (5V/8A max) supply for USB 3.0 devies. Light up 4X high power-consuming USB-A devices simultaneously.
3. 3. PCI Express bus connection, ensure fast and stable using experience lost few transfers' speeds. Never have lost connection issue like external USB HUB does.
4. 4. Fully support USB 3.0 (USB 3.1 GEN1, USB 3.2 GEN1) standard 5Gbps max speed, will backward compatible with USB 2.0 480Mbps speed and USB 1.1 12Mbps speed.
5. 5. PCIE X1 interface design, will works on PCIE X1, X2, X4, X8, X16 slot. X2 slot, do not work on PCI slot. Based on PCIE 2.0 standard, will compatible with PCIE 1.X, 2.X, 3.X, 4.X PCIE slot.
6. 6. Full height bracket mounted on the USB card, will works on Standard Size PCs. Low profile bracket in the package, will works on Slim PCs.

Why Choosing 4 Ports Superspeed 5Gbps PCI Express USB 3.0 Expansion Card

-More choices on adding 4X USB 3.0 ports (5Gbps) on desktop computers for video, audio, photos or files transfer, but also provides stable and fast connection for normal USB device which includes web cameras, USB hub, mice, keyboard, smart phone, video capture, KVM switch etc. It is a low cost and effective way to add USB 3.0 Ports on desktop PCs. All add-on USB ports will not use mother baord USB Main Lan speed, just an extra bandwidth by PCI Express on computers, servers or NAS systems.

- USB 3.0 card provides sufficient power (8A max) supply for USB data device. Experience fast data transfer all the time. Running High power-consuming device simultaneously in all USB ports now. This expansion card is very easy to use and provides two additional SuperSpeed USB ports without sharing/reducing performance as an external USB hub might do.

-built-in power converters. No need to connect any wires inside the PC.
