PCI Express PCIe Gen3.0 x1 x16 Riser Graphics Card Ribbon Extension Cable 25cm PCI-E 1x 16x 3.0 R11SF. Product advantages: 1. Advantages of wire, using German patented wire, using high-quality PCIe connectors, high-frequency support PCIe 3.0 8G/bps stable transmission. 2. The advantage of line length can be customized from 2cm to 2m. 3. The differential signal has no via design and there is no signal attenuation and interference problem of parasitic capacitances and parasitic inductances. 4. High-quality connectors are used. 5. PCB dwarf and fat design, dwarf will not be stuck to the graphics card, plus fat and lengthened design to make the card easier to install, low probability of damage.
