It is made of solid capacitors, equipped with high-performance, high-quality electrical components and full metal shields. Solid capacitors are environmentally friendly and have low impedance. The 4-layer PCB board processing technology increases the product's anti-interference ability and improves the stability of product data transmission. The high transmission speed of USB3.1, playing and watching the power in real time, allows you to open all kinds of large files without waiting for work and open them directly, eliminating the hassle 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 USB-IF certification and complies with 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's power supply.
