[PCI-E1X to 16X extension cable]: Brand new design, you can use 1X-16X, the circuit board PCIe adapter cable is newly launched, safer, more efficient, and more practical [Stable and safe]: The graphics card power supply adopts 8 imported large solid capacitors to make the graphics card power supply more stable and safe.[Reduce the burden on the motherboard]: The 6PIN interface of the adapter card enhances the power supply, which is converted to a 6PIN line through the SATA port, making the power supply of the graphics card independent of the motherboard, thereby reducing the burden on the motherboard when connecting multiple graphics cards.[Sturdy data cable]: 60 cm USB 3.0 data cable, which can flexibly place PCI-E devices. The PCI-E connector uses multi-layer shielded cables and can be connected to 3Meter without signal attenuation.[Support System]: Compatible with all WINDOWS systems, LINUX, No driver is required.The 4 holes on the riser clamp are used for installation.LED indicators and fuses are used on the circuit board.Note:1.This product is suitable for motherboards with PCI-E slots.Please connect the floppy disk drive when using it.When inserting or unplugging the PCI-E extension cable,make sure that the computer has no power.2.The internal cable is specially made.Do not replace it with other data cables.3.To prevent damage to the computer and other equipment,please find the correct cable connection end.4.Use old flat cables for dual-core graphics cards and 16X motherboards.5.When plugging in the cable, make sure you know the direction.Do not insert the cable in the reverse or oblique direction to avoid damage to the device.When inserting, please hold the socket of the device before inserting it to avoid damaging the pins of the socket forcibly.Types: BColour:blackMaterial:PC+metalSize: Adapter board: 130x45mm,USB cable length: 60cmPackage Contents:6 x PCI-E 16X adapter boards6 x PCI-E 1X riser cards6 x USB cables6 x 6pin to 15PIN SATA power cables(As each batch of raw material may be different, the PCI-E riser card may be a little different on the appearance(such as the solid capacitor, USB 3.0 cable, the Chip model), but the function is the same.)Only the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
