It is made of all-solid capacitors, equipped with high-performance, high-quality electrical components, and all-metal baffles. Solid capacitors are environmentally friendly and low impedance. The 4-layer PCB board processing technology increases the anti-interference ability of the product and improves the stability of the product data transmission.The high-speed transmission of USB3.1, playing games and watching the power in real seconds, allows you to open all kinds of large files without waiting for work, and open them instantly, eliminating the trouble of waiting.It supports the new high-speed PCI-E3.0 specification and is backward compatible with the PCI-E2.0 specification. Applicable interfaces: PCI-E2x, PCI-E4x, PCI-E8x, PCI-E16x. The main control is the first to pass the USB-IF certification and conform to the new USB3.1 specification revision 1.1 formulated by Intel.The type-E expansion card uses USB 3.1 to provide high-speed data transfer.The USB 3.1 PCI-E adapter card is small and compact and can be powered from the chassis power supply.Type: riser cardChip: ASM3142Data transfer speed: 1000MB/sProduct size: 120x60x20MMProduct interface: TYPE-E 20PIN PCI-E 4X 8X 16XSupport system: WINXP WIN7 WIN8 WIN10, LINUXMaterial:PCBcolour:BlackPackage Contents:1 x Riser CardOnly 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.
