Green PCB adapter card with dual M.2 slots and PCIe x4 connector

Corn Electronics

Corn Electronics JEYI SK7 M.2 NVMe & NGFF to PCIe 3.0 x4 Adapter Card

SKU CH-XS3N-K2N3H

Adds two M.2 slots — NVMe M-key and NGFF B-key — to a PCIe 3.0 x4 slot with 12 V and 3.3 V power

  • Supports M.2 2230 to 22110 NVMe and NGFF SSDs
  • Tantalum capacitors protect the drive from power spikes
  • Dual 12 V and 3.3 V supply for stable operation
  • PCIe 3.0 x4 interface delivers up to 8 GB/s throughput
  • Twin-slot design fits both M-key and B-key modules

Dual M.2 Adapter for PCIe and SATA

This Corn Electronics JEYI SK7 adapter converts M-key NVMe SSDs to a PCIe 3.0 x4 slot and B-key NGFF SSDs to a SATA slot. It accepts drive lengths of 2230, 2242, 2260, 2280 and 110 mm. Tantalum capacitors provide 12V and 3.3V dual-voltage protection. No driver is required for operation.

Desktop builders adding M.2 storage

The card suits desktop builders adding M.2 storage to a motherboard with PCIe x4, x8 or x16 slots and a SATA port. It is not for laptops or systems lacking a free PCIe slot. NVMe SSDs only support Windows 8 and 10, so older OS users should look elsewhere. NGFF SSDs work with nearly all systems.

PCIe 3.0 x4 interface for NVMe

The single specification that decides compatibility is the PCIe 3.0 x4 interface for NVMe M-key drives. Your motherboard must provide this slot and run Windows 8 or 10 for NVMe boot or storage. The SATA-connected B-key NGFF side works independently on almost any system.

Questions about this item

How do I verify the JEYI SK7 adapter is working after installing an M.2 NVMe SSD?

Install the NVMe SSD into the M-key slot, seat the card in a PCIe x4, x8 or x16 slot, boot Windows 8 or 10, and confirm the drive appears in Disk Management or BIOS.

What comes with the JEYI SK7 and what must I supply separately?

The card includes the dual-slot PCB with tantalum capacitors and mounting hardware; you must provide an M.2 NVMe (M-key) or NGFF (B-key) SSD in 2230, 2242, 2260, 2280 or 110 mm length.

Which JEYI SK7 version should I choose for a 2280 NVMe drive versus a 2242 NGFF drive?

A single JEYI SK7 card handles both: the M-key slot takes NVMe drives up to 2280, while the B-key slot accepts NGFF drives such as 2242, all on the same PCIe 3.0 x4 interface.
