Vszerda M.2 OCuLink Adapter for ThinkBook 14+

This adapter converts the internal M.2 M-key slot of a 2022-2023 ThinkBook 14+ into an OCuLink SFF-8612 port. It enables connection of an external graphics card or NVMe SSD using a separate cable and power supply. The board is designed exclusively for this laptop model and will not fit the 16+ variant or other devices.

PCIe 4.0 x4 bandwidth limit of 32 Gbps

The adapter passes four lanes of PCI Express 4.0 signals through the NVMe 1.2 protocol without adding latency or requiring drivers. Performance matches the host slot capability, so the external device operates at the same speed as an internal drive. No protocol conversion or software layer is introduced by the board.

67-pin M.2 male to SFF-8612 female construction

The compact PCB plugs directly into the laptop's M.2 slot and presents a standard OCuLink receptacle for a secure screw-lock cable. No additional mounting hardware is included, so the external cable routes out of the chassis opening. The passive design adds no active components between the CPU and the peripheral.

Questions about this item

Should I choose the SFF-8612 or SFF-8611 connector version for my ThinkBook 14+?

The adapter provides a single SFF-8612 female port; pair it with a cable that matches your external device's SFF-8611 or SFF-8612 socket.

What does the 32 Gbps rate mean when I plug in an external GPU or SSD?

The card passes PCIe 4.0 x4 signals through the NVMe protocol, so the external device sees full Gen 4 bandwidth up to 32 Gbps.

Which interface standard does the OCuLink port follow and what does it limit?

The port follows the OCuLink SFF-8612 specification, capping the link at PCIe 4.0 x4 speeds for any attached graphics card or SSD.
