HOOCCC M.2 to OCulink SFF-8611 Ext Cable, NVMe PCIe 4.0 x4 Gen4 External GPU Dock Cable Without Buckle 10cm
- Item #: 9SIVUB0M4V0933
- Mfr. Part #: OC1C
- M.2 M-Key to OCuLink High-Speed Conversion This adapter cable converts M.2 M-Key NVMe interface to OCuLink SFF-8611 / SFF-8612, supporting PCIe 4.0 x4 Gen4 with transfer speeds up to 64Gbps; backward compatible with PCIe 3.0 for external GPU docks, SSDs, and PCIe expansion devices.
- Premium Gold-Plated Contacts & Signal Stability Features 5U thick gold-plated pins for reliable conductivity, lower contact loss, and repeated plugging resistance; combined with silver-plated, aluminum foil shielded cabling to reduce signal interference and ensure stable high-speed transmission with minimal loss.
- Flexible Flat Cable Design for Compact Builds The slim, flexible ribbon-style cable allows easy routing in tight spaces such as mini PCs, laptops, and small form factor desktops; shielding and silver-plated construction help maintain PCIe 4.0 signal integrity even in compact installations.
- Adjustable M.2 Mounting Length The M.2 end includes pre-marked cut lines supporting 2230 / 2242 / 2260 / 2280 SSD sizes, letting you trim the positioning section to fit different M.2 slot lengths; optional Version A includes a 25mm positioning buckle with screws for a more secure, fixed mount.
- Wide Compatibility for External PCIe Expansion Ideal for Mini PC, Desktop PC, Laptop, and external PCIe enclosures; works with eGPU setups, NVMe SSD expansion, and other PCIe x4 devices

M.2 M-Key to OCuLink SFF-8611 / SFF-8612 Extension Cable for External PCIe 4.0 x4 Expansion
This high-speed adapter cable bridges an M.2 M-Key NVMe PCIe 4.0 x4 interface to an OCuLink SFF-8611 or SFF-8612 port, enabling external GPU (eGPU) dock connections, NVMe SSD expansion, and other PCIe peripheral links. It delivers up to 64Gbps bandwidth under PCIe 4.0 Gen4 and remains backward compatible with PCIe 3.0 systems.
The flexible, silver-plated cable features aluminum foil shielding to reduce signal interference and maintain low-loss transmission over the cable length. Gold-plated contacts (5U thick) provide reliable conductivity, lower contact resistance, and improved durability for repeated installations.
The M.2 end supports 2230 / 2242 / 2260 / 2280 module lengths, with pre-marked lines allowing you to trim the positioning section to fit your specific M.2 slot. Choose the version with a 25mm positioning buckle and mounting screws for a more secure fit, or the version without the buckle for simpler cable-only routing in compact builds.
Ideal for Mini PCs, desktop PCs, laptops, and small-form-factor setups that need external PCIe expansion. Please verify that your host device has a compatible M.2 M-Key NVMe slot and that the dock or device side uses a matching OCuLink SFF-8611 / SFF-8612 interface.
Important: This cable is not hot-swappable. Always power off and fully disconnect your devices before connecting or disconnecting the cable to avoid damage to your hardware.
