Features: Adopts 4 black solid capacitors to make the graphics card power supply more stable and safe. 4PIN interface Adapter card 12VDC-DC strengthens the power supply, so that the power supply of the graphics card is independent from the main board, thereby reducing the burden on the motherboard when connecting multiple graphics cards. Graphics card slot uses the original imported connector, and the graphics card is better in contact with the connector. The PCI-E connector uses multiple layers of shielded wire for up to 3 meters without attenuating the signal. USB cable is soft and stable, and the wiring is convenient, and the graphics card can be placed at will. The slot is equipped with a fixed buckle, which makes it easier to remove the graphics card and the fixed graphics card. The graphics card will not fall off the slot. The wire is made of the most stable material to ensure signal integrity. Power cord is made of pure copper wire, which avoids burning the wire during mining. Specification: Product Name: PCI-E 1X TO 16X 4PIN Product model: PCIE 1X TO 16X Wire length: 60 cm / 1.97ft Product Interface: PCI-E 1X PCI-E 16X Support system: Compatible with all for WINDOWS/LINUX/MAC systems Size: approx. 12.5 * 4.4 * 1.5cm / 4.9 * 1.7 * 0.6in Package list: 1 * Power Cord 1 * USB Cable 1 * Riser Card 1 * Adapter Note: 1. This extension cable is for the motherboard PCI-E slot (1X, 2X, 4X, 8X, 16X). Please insert the floppy drive power cord when using. When plugging and unplugging the PCI-E extension cable, be sure to disconnect the cable from the computer, and be sure to read the precautions when using it! 2. The matching wire is customized. Please don't find a line casually and plug it in! 3. When inserting the cable, be sure to recognize the direction. Do not insert the reverse or insert the offset to prevent the device from being burned. When plugging the cable, first hold the socket of the device and then plug the cable to avoid inserting the socket pin with excessive force. 4. Dual-core graphics card is recommended to use the old cable, the motherboard is 16X is also recommended to use the old cable. 5. Due to different production batches, the color of the buttons and capacitors of the graphics card socket may be different. 1、Adopts 4 black solid capacitors to make the graphics card power supply more stable and safe. 2、4PIN interface Adapter card 12VDC-DC strengthens the power supply, so that the power supply of the graphics card is independent from the main board, thereby reducing the burden on the motherboard when connecting multiple graphics cards. 3、Graphics card slot uses the original imported connector, and the graphics card is better in contact with the connector. 4、The PCI-E connector uses multiple layers of shielded wire for up to 3 meters without attenuating the signal. 5、USB cable is soft and stable, and the wiring is convenient, and the graphics card can be placed at will.
