SMUGDESK

SMUGDESK PCIe 5.0/4.0 x4 to MCIO 38Pin Female Host Adapter

SKU CH-6B8T-KGNNV

Adds a 38-pin MCIO 4I port to a PCIe 5.0 x4 slot for NVMe U.2 SSD connection at 128Gbps

  • PCIe 5.0 x4 delivers 128Gbps bandwidth for ultra-fast NVMe U.2 SSD data transfer
  • MCIO 38Pin female port connects directly to U.2 SFF-8639 NVMe SSD via MCIO-to-U.2 cable
  • Fits PCIe x4/x8/x16 slots and supports Windows/Linux/macOS with bootable system drive capability
  • Gold-plated contacts with pure copper traces ensure enterprise-grade signal integrity for stable long-cable transmission
  • Plug-and-play full-height bracket installs without drivers for server and workstation storage expansion

PCIe 5.0 x4 to MCIO 38Pin Adapter

This adapter converts a PCIe Gen 3/4/5 x4 slot into an MCIO 4I (SFF-TA-1016) female port for NVMe U.2 SSD connectivity. It suits builders adding high-speed enterprise storage to motherboards or servers. The x4 interface delivers up to 128Gbps bandwidth for demanding workloads. Not for systems lacking a free PCIe x4, x8 or x16 slot.

Sustained Signal Integrity

Gold-plated contacts and pure copper traces maintain stable transmission over extended cable lengths. An optional redriver further preserves signal quality during continuous heavy I/O. The design targets reliable operation in workstation and server environments.

Pre-Installation Checks

Verify the motherboard or server has an available PCIe x4, x8 or x16 slot and a compatible MCIO-to-U.2 cable for the target SSD. Confirm the operating system supports NVMe boot if the drive will serve as the primary system volume. Ensure the chassis accommodates a standard full-height bracket.

商品問答

How much power does the SMUGDESK PCIe 5.0 x4 to MCIO 38Pin adapter draw when running continuously?

The adapter is a passive signal device with no active components, so its power draw is negligible compared to the NVMe U.2 SSD it connects.

What cable do I need to attach a U.2 NVMe SSD to this MCIO 38Pin host adapter?

You need an MCIO-to-U.2 (SFF-8639) cable to link the 38-pin MCIO 4I port to the drive.

Will this PCIe 5.0 x4 card work in an older motherboard that only has PCIe 3.0 x16 slots?

Yes, it fits x4, x8 or x16 slots and operates at Gen 3, 4 or 5 speeds depending on the platform.
