M.2 NVMe SSD to PCIe 4.0 x1 Adapter Card – 16Gbps Full-Speed PCI-E Gen4 M-Key Expansion Card Foundation, Solid-State Drive Riser Internal Add-On Card Adapter for Desktop PC

Breathe new life into your desktop storage architecture with the JEYI M.2 NVMe SSD to PCIe 4.0 x1 Adapter Card (Model: SK1). Categorized as a high-performance Add-On Card, this hardware expansion riser converts an open PCI Express x1 slot into a dedicated lane for any standard M-Key 2280 NVMe solid-state drive. Supporting PCIe Gen4 speeds up to a blistering 16Gbps bandwidth, it provides a seamless option for adding an extra high-performance scratch disk, backup drive, or high-speed gaming warehouse to your PC without replacing your motherboard. Built with an open PCB design that promotes natural heat dissipation and paired with a secure low-profile mounting frame, the JEYI SK1 ensures your data transfers stay exceptionally stable and free from thermal bottlenecks.

Key Features & Benefits

• PCIe Gen4 x1 Full-Speed Efficiency: Engineered to tap directly into PCI-E 4.0 architecture, delivering up to 16Gbps full-speed bandwidth while maintaining flawless backward compatibility with PCIe 3.0 and 2.0 motherboard slots.

• Smart Storage Expansion: An ideal, cost-effective upgrade path for desktops that lack native M.2 slots or have already used up their primary motherboard storage links, allowing you to seamlessly integrate high-tier NVMe storage.

• Optimized Passive Cooling Build: The slim, open-air circuit layout keeps air flowing smoothly across both sides of the mounted M.2 drive, reducing heat buildup and eliminating performance throttling during long data write sessions.

• All-Size 2280 NVMe Compatibility: Tailored specifically to support standard M-Key M.2 NVMe solid-state drives in the highly popular 2280 size layout (22mm wide by 80mm long), including flagship consumer drives.

• Rigid Structural Signal Grounding: Assembled with high-density gold-immersion pins and heavy-duty grounding capacitors that suppress electromagnetic interference, giving you clean, stable data lines and rock-solid boot safety.

• Low-Profile Case Bracket Ready: Arrives with standard full-height and low-profile expansion brackets, ensuring a clean, perfect hardware fit inside standard mid-tower desktops or slim Small Form Factor (SFF) office workstations.
