Cable Supermicro CBL-MCIO-1232M5 MCIO x8 STR a 37cm - Cable

High-speed internal connections in dense server environments often suffer from signal integrity issues and space constraints. The Supermicro CBL-MCIO-1237M5 solves this by providing a reliable, straight MCIO x8 to MCIO x8 link that supports PCIe Gen5 data rates up to 32 GT/s per lane. With a compact 37 cm length, it minimizes cable clutter while maintaining full bandwidth for NVMe backplanes and other PCIe devices.

Who is it for

This cable is intended for IT professionals and system integrators deploying Supermicro servers, workstations, or storage systems that require high-speed internal PCIe connectivity. It is ideal for connecting motherboards to NVMe backplanes, riser cards, or other internal devices using MCIO x8 connectors.
