Jansicotek Superspeed 4 Ports PCI-E to USB 3.0 Expansion Card - PCI Express(PCIe) Expansion Card USB Card for Desktop PC Support Win XP Win7 Win 8 Win 10 Win 11 Linux

• 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
• 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)
• 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.
• Built in Self-Powered Technology: Powerd by PCI-Express 12V power supply, no need extra power supply
• OS Compatibility: Plug-and-play in Windows/Linux (Note: Not support Mac OS); 
• Installation: PCI-Express X1 slot installation

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. 

Product Advantage:

• 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. 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. 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. 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.
