Features: Brand new and high quality. 4 slots provide great expandability. Connects directly to the card without an extension cable, can be fixed to the chassis. PCI-E slot power solution, no extra power cable needed. Only one cable is needed to connect the lock, making setup and installation simple and convenient. Includes an IC cooler. Note: 1. This extension applies to the motherboard's PCI-E 1X slot; connect the floppy drive power cable. When connecting the PCI-E extension, the computer needs to reconnect broken cables. 2. The shape of the complete wire rod set is customized; never grab the line to connect. Remember this! 3. When connecting the wire, you must identify the direction, do not reverse or displace it to avoid burning equipment. Connect the wire to the equipment's socket first, then connect the wire to avoid breaking the pin socket if you connect too forcefully.
