Ⅰ. 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. Ⅱ. It is an innovative solution that turns out two PCI slots through the PCI-E slot, supporting not only a single PCI slot but also dual PCI slots to work simultaneously. With a power of 16W, it does not require an additional power supply, and there is a SATA interface on the board to enhance power extraction for more flexible use. The PCI slot power supply uses solid capacitors for filtering, enabling operation in both high and low temperature environments. Ⅲ. 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. Ⅳ. Note: The USB cable of this adapter card is specially customized and cannot be used as a substitute for a USB3.0 cable, nor can it be inserted into the motherboard's USB3.0 interface to avoid damaging the motherboard and adapter chip. Ⅴ. Because some PCI cards have two anti-dumb slots, the gold finger can be inserted into the PCI slot, so when installing PCI cards, attention must be paid to the direction to avoid reverse insertion. Ⅵ. Material: PCB; colour: Black+Blue; Package Contents: 1 x PCI Riser Card. Only the above package content is included, and other items are not included. Ⅶ. Note: Light reflection and different displays may cause the color of the item to differ slightly from the real thing. The measurement allowed error is +/- 1-3cm.
