What this product does Adds one SFF8612 expansion interface to your 2022–2023 ThinkBook 16+ (AMD 8845 CPU) to expose a PCIe 4x NVMe connection for external devices. Enables connection of a single NVMe SSD or a compatible external graphics device using an optional cable and external power. Key benefits — why you need it Expands a fixed laptop configuration: provides a dedicated SFF8612 port so you can add speed storage or a single external PCIe device without replacing internal components. Delivers PCIe 4x performance using the NVMe protocol for lowlatency, throughput storage or peripheral use. Keeps compatibility focused and predictable by working specifically with the supported ThinkBook model and CPU combination. Compatibility and limitations Designed exclusively for 2022–2023 Lenovo ThinkBook 16+ with AMD 8845 CPU. Not compatible with ThinkBook 14+, other ThinkBook models, or other laptop brands and models. External device connection (e.g., SSD or GPU) requires an optional cable and separate power source as applicable. Performance and function Exposes PCIe 4x lanes using the NVMe protocol to support modern performance NVMe SSDs and PCIe peripherals that operate over an SFF8612 interface. Ideal when you need fast local storage expansion or to connect a single external PCIe device where internal options are limited. Practical applications capacity storage expansion: add a fast NVMe SSD for large project files, video editing scratch space, or local backups with NVMelevel throughput. GPU prototyping or light external acceleration: connect a single compatible external graphics device via optional cable and external power for specific GPUaccelerated tasks or testing. Specialized peripheral connection: attach any single PCIe device that supports NVMe/PCIe 4x over SFF8612 for niche workflows. Important notes This converter only works with the specified ThinkBook 16+ (2022–2023) AMD 8845 CPU model. Do not use with ThinkBook 14+ or other laptops. Optional cable and external power are required to connect and power some devices; these are not included.
