This PCIe extension cable is ideal for using a 1x slot that can normally be blocked by an adjacent bulky graphics card. I use it to connect a PCIe sound card and it works fine. The 28ga patch cord is surprisingly high quality, with good thickness and strength while remaining very flexible. The cable's 80ยฐC temperature range is sufficient for most applications, but care must be taken to route it separately (or isolated) from the hottest components of a high-performance graphics card. The connectors at both ends of the cable are of high quality. Note: The edge card slot is beveled correctly, and the 1x blue card slot is supplied by Foxconn (the same as the one on the motherboard). Generally no issues and consistently excellent quality. Highly recommended.
