Function and design: PCIe x16 90 degree adapter that converts the PCI Express slot into the NGFF Key M interface to connect M.2 NGFF Key M devices, expanding storage options and upgrade flexibility. Material and durability: Constructed with PCB material designed to deliver stable signal transmission and longterm durability for professional use. Target users: Suitable for professionals, gamers, and computer builders who need efficient space saving for building and upgrading systems. Space efficiency: 90 degree orientation helps install in tight computer cases and facilitates hardware configuration without compromising performance or accessibility. Compatibility and performance: Designed for PCIe x16 slots and NGFF Key M interface devices, supporting standard PCIe signaling to maintain device performance. Use scenario 1: In a compact desktop or small form factor build with limited M.2 slots, install an M.2 NGFF Key M device via a PCIe x16 slot to add storage without expanding the motherboard footprint. Use scenario 2: In a workstation or test bench where M.2 slots are occupied or unavailable, add an extra M.2 NGFF Key M device through a PCIe x16 slot for additional storage or testing. Use scenario 3: In spaceconstrained builds, use the 90 degree adapter to improve airflow and cable routing while enabling easy access to the M.2 device for upgrades or maintenance.
