SMUGDESK 50cm M.2 NVMe PCIe 4.0 Extension Cable OCuLink SFF-8611

SKU CH-CG88-TNTSM

Extends an M.2 NVMe slot 50 cm via PCIe 4.0 OCuLink SFF-8611 for flexible drive placement and full-speed performance

  • PCIe 4.0 protocol keeps NVMe SSD at full speed
  • OCuLink SFF-8611 4i connector locks firmly for stable transmission
  • NGFF M-Key slot fits M.2 NVMe M-Key drives directly
  • 50cm length moves SSD away from heat sources for cooler operation
  • Shielded cable and rigid PCB block interference for reliable long-term use

M.2 NVMe PCIe 4.0 Extension Cable

This 50-centimetre cable extends an M.2 NVMe slot to a remote position inside a desktop chassis. It uses an NGFF M-Key adapter board on the drive side and an OCuLink SFF-8611 connector on the motherboard side. The design targets DIY builders and modders who need to relocate a solid-state drive for better airflow or cable routing.

For chassis modders and upgrade projects

Builders who want to move an M.2 NVMe drive away from the CPU or graphics card heat zone will benefit from the 50cm length and shielding. Users whose motherboard lacks an OCuLink SFF-8611 port cannot connect this cable. Systems limited to PCIe 3.0 signalling will not reach the full 4.0 bandwidth the cable preserves.

OCuLink SFF-8611 4i interface

The cable terminates in an OCuLink SFF-8611 4i connector that locks securely to a compatible motherboard or controller port. This specific interface is the single specification that determines whether the extender can be installed. Verify that your host provides this exact port before purchase.

Questions about this item

What comes in the box and what must I buy separately?

The package contains the M-Key adapter board and the 50cm OCuLink SFF-8611 cable. You must supply your own M.2 NVMe M-Key SSD and a motherboard with an OCuLink SFF-8611 PCIe 4i port.

How do I choose the right version or capacity?

This item is a single 50cm PCIe 4.0 extension cable; there are no capacity or version options to select. Match it to an M.2 NVMe M-Key drive and an OCuLink SFF-8611 4i motherboard connector.

What does the PCIe 4.0 x4 rating mean once the cable is installed?

It means the cable maintains full PCIe 4.0 x4 bandwidth so the NVMe SSD keeps its original read and write speeds without throttling or signal loss over the 50cm distance.
