  • Power devices with 4-pin FDD connector for 12V supply
  • Supports M.2 2230 form factor for compact installation
  • Works with PCI-E 1X, 4X, 8X, 16X cards at 1X speed
  • Compatible with Windows XP through 11 and Linux without drivers

M.2 Key A-E to PCIe 4x adapter

This adapter connects a standard PCIe device to an M.2 Key A or E slot on a motherboard. It accepts M.2 type 2230 modules and provides a 270-degree angled PCIe 4x connector. A 4-pin FDD power connector supplies 12V power when the installed device requires it.

Replaces direct M.2 card installation

The cable allows a full-size PCIe card to be used where only an M.2 Key A-E slot exists. The upgrade is worthwhile when a system lacks a standard PCIe slot but has a compatible M.2 interface supporting PCIe signalling rather than CNVio2. Speed is limited to PCIe 1x throughput because the M.2 link width restricts bandwidth.

Sustained operation with external power

High-quality wire and connectors maintain PCIe 3.0 stability during extended transfers. The optional 4-pin FDD power feed prevents voltage drop on the 12V rail when the attached card draws continuous current. No drivers are required across Windows XP through 11 and Linux.

Questions about this item

Does the 270° M.2 Key A-E plug clear low-profile brackets?

The 270° connector bends back toward the board, so it fits inside tight chassis where a straight riser would hit the bracket or side panel.

What step do installers forget when seating the 2230 M.2 module?

They often omit the single mounting screw that locks the M.2 card to the standoff; without it the edge connector can lift and drop link speed.

When should the 4-pin FDD power lead be connected?

Attach the FDD plug only if the PCIe card requires 12 V auxiliary power; leave it disconnected for cards that draw all power from the slot.
