SMUGDESK

SMUGDESK M.2 NGFF to PCIe X4 Adapter Card, PCIe 3.0 M-Key & B-Key with 12V+3.3V Dual Power & SATA 3.0 Port

SKU CH-2H17-GW6PE

Converts a PCIe 3.0 X4 slot to dual M-Key and B-Key M.2 plus a SATA 3.0 port with 12V+3.3V dual power

  • Dual M-Key and B-Key slots accept NVMe and SATA drives
  • PCIe 3.0 X4 specification enables high-speed data transmission
  • 12V and 3.3V dual power supply ensures stable operation
  • Integrated SATA 3.0 port adds an extra storage channel
  • Plug-and-play design fits PCIe X4, X8 and X16 slots

Dual-Key M.2 Adapter Card

This SMUGDESK adapter converts a PCIe X4 slot into an M.2 NGFF interface supporting both M-Key and B-Key solid state drives. It accepts NVMe and SATA SSDs for broad compatibility across different drive types. The card fits PCIe X4, X8, and X16 slots in desktops and workstations.

PCIe 3.0 Upgrade Path

The adapter adopts PCIe 3.0 X4 specification for high-speed data transmission and adds an integrated SATA 3.0 port for an extra storage channel. It replaces single-key brackets or basic risers that only support one M.2 protocol. The jump is worthwhile when a motherboard lacks native M.2 slots or needs simultaneous NVMe and SATA connections.

Plug-and-Play Installation

Installation is plug-and-play with no drivers required, and the 12V + 3.3V dual voltage supply delivers stable power for long-duration operation. Builders must verify the physical key of their M.2 drive matches the M-Key or B-Key slot, as NVMe drives will not function in a B-Key-only socket. The SATA port needs a separate data cable to the motherboard.

Highlights

  • PCIe 3.0 X4 specification enables high-speed data transmission
  • 12V and 3.3V dual power supply ensures stable operation
  • Integrated SATA 3.0 port adds an extra storage channel
  • Plug-and-play design fits PCIe X4, X8 and X16 slots

Questions about this item

Will this SMUGDESK adapter fit in a standard PCIe X4, X8 or X16 slot on my motherboard?

Yes, the card is designed to plug directly into any PCIe X4, X8 or X16 slot, so it fits standard desktop and workstation boards.

Do I need to connect the 12V and 3.3V power cables before installing an M.2 NVMe or SATA SSD?

Connect both the 12V and 3.3V power leads first, then insert the M.2 drive into the M-Key or B-Key slot and secure it with the screw; skipping the power cables is the common mistake.

Can I add a 2.5-inch SATA drive later using the on-board SATA 3.0 port?

The integrated SATA 3.0 port provides an extra channel, so you can attach a standard SATA SSD or hard drive whenever you need more storage.
