SMUGDESK M.2 NVMe SATA PCIe 3.0 X4 Adapter 12V 3.3V

SKU CH-Z8Q2-JDC8J

Converts a PCIe 3.0 X4 slot to dual-key M.2 with 12V and 3.3V power plus SATA 3.0 expansion

  • Dual M-Key and B-Key design fits most M.2 NVMe and SATA SSDs
  • PCIe 3.0 X4 compliance delivers fast and smooth data transmission
  • 12V plus 3.3V dual voltage supply ensures stable power output
  • Integrated SATA 3.0 port adds extra storage expansion options
  • Plug-and-play installation works in desktops, workstations and servers

Dual-Key M.2 Adapter for NVMe and SATA SSDs

This adapter converts a PCIe X4 slot into an M.2 interface with dual M-Key and B-Key support. It accommodates both NVMe and SATA solid-state drives using a single card. The design follows the PCIe 3.0 specification and includes a 12V plus 3.3V dual voltage supply for stable power delivery.

Builders Adding M.2 Storage to PCIe Slots

The card suits desktop, workstation or server owners who need to install an M.2 drive where no native slot exists. It also provides a SATA 3.0 port for additional storage expansion. Users whose motherboards already offer dedicated M.2 connectors or who require PCIe 4.0 or 5.0 bandwidth should consider other solutions.

Simple Plug-In Installation

Installation is a straightforward plug-and-play process: seat the card in a PCIe X4 slot, mount the M.2 drive with the appropriate key, and connect any SATA device if required. No drivers are needed for the adapter itself. The most common issue is neglecting to secure the drive with its retention screw, which can cause intermittent contact.

Questions about this item

Does my motherboard need a free PCIe 3.0 x4 slot for this adapter?

Yes, the card plugs into a PCIe 3.0 x4 slot and uses that link for data transfer.

Will a SATA M.2 SSD work on the M-key or B-key slot of this card?

Both M-key and B-key sockets accept SATA M.2 drives; the onboard SATA 3.0 port routes the signal to the motherboard.

How can I confirm the 12V and 3.3V rails are delivering power after installation?

The SSD should appear in BIOS and the operating system without errors, showing the dual-voltage supply is active.
