1、Expand To 2 Interfaces: PCI E 1X to 2 PCI E multiplier card can realize 1 interface can be expanded to 2 PCI E interfaces, effectively solving the problem of lack of PCI E interface on the motherboard 2、Direct Power Supply: The main control board uses the PCI E interface to directly supply power, no external power cord is required, and the two PCI E interfaces are gold plated, the main control board is not subject to external interference 3、Stable Transmission: The PCI E riser card adopts for ASMedia ASM1182E master controller, which ensures high speed and stable transmission 4、Wide Compatibility: The PCI E expansion card is compatible with PCI E 4X, 8X, 16X. The system supports for DOS, for Linux, for Win7, for Win8, for Win10, for Win11 and other systems 5、Easy Installation: Before installation, the motherboard needs to be powered off, and then straighten the slot to effectively reduce interface interference, ensure data reliability, and improve work efficiency 1 x PCI E 1 to 2 Riser Card Item Type: PCI E 1 to 2 Riser CardMaterial: Metal, PlasticInterface: 2 x USB 3.0 A Female (PCI E signal, cannot insert USB device)Input Interface: PCI E 1XInterface Speed: PCI E 2.0Support Slot: PCI E 1X, 4X, 8X, 16XProduct Master: For ASMeida ASM1182ESupport System: For WIN XP, for WIN 7, for WIN 8, for WIN10, for WIN11, for LINUX
