SMUGDESK PCIe 3.0 x4 to M.2 M-Key 80 mm NVMe Adapter with 4.0F Super Capacitor

SKU CH-SV03-M1V0M

PCIe 3.0 x4 adapter adds an M.2 M-key 80 mm NVMe slot with a 4.0F super capacitor that protects data during power loss

  • PCIe 3.0 x4 interface enables high-speed NVMe performance
  • 0F super capacitor protects data during power failure
  • Designed for 80 mm M-key NVMe SSDs
  • Optimized circuit ensures low-latency signal transmission
  • Plug-and-play installation suits servers and workstations

PCIe 3.0 x4 to M.2 80 mm Adapter

This adapter converts a PCIe 3.0 x4 slot into an M.2 M-Key connector for 80 mm NVMe SSDs. It targets server and workstation builders who need reliable high-speed storage expansion. The design focuses on stable signal transmission under sustained heavy workloads.

4.0F Super Capacitor Protection

The onboard 4.0F super capacitor supplies hold-up power during sudden mains loss. This feature protects in-flight write operations and prevents data corruption on the attached NVMe drive. It addresses the critical requirement for data integrity in high-security and industrial environments.

Plug-and-Play Installation

Installation requires inserting the card into a compatible PCIe slot and securing the 80 mm NVMe SSD with the provided screw. No drivers or software configuration are needed for the adapter itself. Builders must verify their platform supports PCIe bifurcation or M.2 NVMe boot if the drive is intended as a primary boot device.

Questions about this item

Will the 4.0F super capacitor need replacement after a certain period?

The 4.0F super capacitor is built into the adapter and designed for long-term power-failure protection without a user-serviceable replacement interval.

What is the throughput ceiling of the PCIe 3.0 x4 link when the 80 mm NVMe drive runs sustained heavy workloads?

The PCIe 3.0 x4 interface sets the maximum sustained bandwidth available to the NVMe SSD, so the link itself becomes the first limit under continuous heavy I/O.

Does the adapter generate noticeable heat or noise when powering an 80 mm NVMe SSD all day in a server?

The card has no moving parts and relies on the system's airflow; the optimized circuit design keeps latency low during long-term heavy-load operation without adding audible noise.
