PCIe to USB Expansion Card
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.
