1. The motherboard end of the iron bar open slot can be directly led out from the slot or placed in the chassis to connect to the slot connection board. The power indicator uses a blue LED, which can transmit blue light after power on. 2. Innovative solution: through the PCI-E slot to turn out two PCI slots, supporting dual PCI work at the same time. Power 16W does not require additional power supply, and there is SATA on the board to enhance power extraction for more flexible use. PCI slot power supply uses solid capacitors for filtering, which can work in high temperature and low temperature environments. 3. Product Parameters: Product Model: PCIE TO 2PCI; Product Interface: PCI slot; Product speed: PCI-E 1X; Support Protocol: PCI-E or NVME; Main control chip: ASMeida ASM1083; System support: WIN7/WIN8/WIN10/WIN11/LINUX. 4. Note: This adapter card USB cable is specially customized, cannot be used in place of USB3.0 cable, cannot be inserted into the motherboard USB3.0 interface to use, to avoid burning the motherboard and adapter chip. 5. Because some PCI cards have two anti-dumb slots, the gold finger can be inserted into the PCI slot, so the installation of PCI cards must pay attention to the direction and not insert reversely. 6.
