workman is excellent, and the number of peripheral components is sufficient and the layout is uniform Neat, can eliminate interference to the greatest extent, greatly improve stability Fuses and capacitors Each interface is equipped with independent interface protection insurance. When external u5b equipment is short circuited and the current is too high, etc In case of failure, it can cut off the power supply instantaneously, so as to protect the peripherals and computers from damage, and automatically return to normal after troubleshooting. Each interface is equipped with independent regulated capacitor, which can ensure stable power supply of each interface, and the capacitor adopts solid-state paste Chip, can withstand 250 Celsius high temperature Four phase power supply module is provided on the card, and only one USB3.0 interface is provided for each phase power supply 2A power supply, a total of 8A power supply. The closed high-power inductor with 12mm x 12mm R is adopted, which can kill the market 10 mm x 10 mm ordinary inductance on the surface USB3.0 needle port:The back end of the card is equipped with two usb3.019 pin pin outlets. If the front of the chassis is equipped with USB3.0 If there is no built-in 3.0 interface on the chassis, you need to cooperate Front panel use By using thickening process, gold has good conductivity, strong oxidation resistance and surface gold deposition Technology can ensure more stable transmission Expansion card Model: u3n014s + pw4 Number of interfaces: 4 Applicable slot: pci-ex1x4x8x16 Current: independent 2a for each interface Operating system: support XP, win7win8win8.1win10 Transmission rate: 5GB Colour: black Material: ABS Size: 120x69x59mm Package Contents: 1 * expansion board Only the above package content, other products are not included. Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
