About PCIe Extender
A PCI-E extender, or PCI-E riser cable, is an internal computer component readily available from eBay sellers. While these cables are not vital, they allow you to connect multiple video cards to your GPU, Because the extenders, or risers, lift the video cards away from the motherboard, they also help to prolong the life of the video cards and help to achieve higher speeds and better performance. By lifting the video card components away from the motherboard, you encourage better airflow and greater available surface area. This helps to cool the cards and components more effectively, which keeps them running at optimal speed and performance and extends their lifespan, reducing the risk of overheating. If you choose a powered PCI-E extender, the cable and its power supply power the video card to which it is connected. Extend the life of your video card, improve the video quality and performance of your computer, and get a better overall experience when you install a PCI-E extender.
