Bare circuit board adapter with USB Type-A plug and M.2 slot for NVMe SSD

Enfain

Enfain nvme to USB 3.1 Type-A M.2 adapter JMS583

SKU CH-C45T-P1S4J

Bare-card M.2 NVMe to USB 3.1 Type-A adapter with JMS583 chip, backwards compatible with USB 2.0 and 3.0

Model USB 3.0

  • Bare card design plugs straight into a USB port, no enclosure or cables needed
  • Open board layout exposes the SSD for direct airflow and better heat dissipation
  • JMS583 3.1 chip enables USB 3.1 performance with PCIe NVMe M.2 drives
  • Backward compatible with USB 2.0 and 3.0 ports for wider system support
  • Works only with PCIe NVMe M.2 SSDs, not AHCI or SATA M.2 drives

Bare card NVMe to USB 3.1 adapter

The Enfain JMS583 adapter is a bare circuit board that converts a PCIe NVMe M.2 drive to a USB 3.1 Type-A connection. It plugs directly into a computer without an enclosure or cables. The open design helps dissipate heat from the drive during operation.

For adding an NVMe drive over USB

This suits users who want to access a PCIe NVMe M.2 SSD through a USB 3.1, 3.0 or 2.0 port without a full enclosure. It does not support M.2 drives using AHCI or SATA protocols, so buyers with those drive types should look elsewhere.

Handles mainstream PCIe NVMe drives

The JMS583 chip supports common PCIe NVMe M.2 SSDs at USB 3.1 speeds. Performance is limited by the USB 3.1 interface, so very high-speed drives will not reach their full potential. Drives using SATA or AHCI protocols are not recognised.

Questions about this item

What type of M.2 drive do I need to already own for this adapter to work?

You need an M.2 NVMe SSD that uses the PCIe protocol; the adapter does not support M.2 SATA or AHCI drives.

Will this adapter run at USB 3.1 speeds if I plug it into my older USB 3.0 port?

The adapter supports USB 3.1, 3.0 and 2.0 interfaces; on a USB 3.0 port it will operate at USB 3.0 speed.

How can I confirm the JMS583 adapter is functioning correctly after I insert my NVMe drive?

The bare card has no shell or LEDs; you verify operation by checking that the NVMe drive appears in your OS file explorer or disk management.
