NGFF M.2 A-Key power cable

This Vszerda internal power cable provides the 26-pin connection and 6-pin/8-pin power feeds required by the EXP GDC external graphics dock. It links a laptop’s NGFF M.2 A-Key slot to the dock so a discrete GPU can be used for gaming, engineering measurement, data collection, server debugging or GPU computing. The cable includes a dual TD compatible switch for hardware-conflict resolution and multi-power automatic switching with soft-start support. Imported components and multistage isolation protect the signal path.

Laptops with an NGFF M.2 A-Key slot

The cable suits owners of laptops that expose an NGFF M.2 A-Key interface and want to attach the EXP GDC dock via the supplied 26-pin data line. It also works with 54-type and 34-type ExpressCard slots through the same dock. Builders whose machines only offer an M-Key slot cannot use this cable. Systems without any NGFF M.2 A-Key or ExpressCard connection need a different docking approach.

26-pin NGFF M.2 A-Key interface

The decisive specification is the 26-pin NGFF M.2 A-Key connector on the cable; the laptop must provide this exact keying and pin count for the dock to communicate. The cable also carries a 6-pin connector for GPU auxiliary power and an 8-pin connector for the EXP GDC unit itself. If the laptop’s M.2 slot uses a different key or pin layout, the cable will not fit or function.

Questions about this item

How can I verify the NGFF M.2 A-Key cable is functioning after connecting it to the laptop and graphics card?

The dock powers on and the external GPU appears in Device Manager without error codes, while the Dual TD switch resolves any hardware conflicts during boot.

What comes with the EXP GDC dock and which cables must I source separately?

The package includes the NGFF M.2 A-Key data cable, an ExpressCard data line supporting 54 and 34 type interfaces, plus 6-pin and 8-pin power cables; you must supply your own graphics card and ATX power supply.

Which M.2 key type should I select for my laptop's slot?

Choose the A-Key version, as this cable is built specifically for NGFF M.2 A-Key slots and will not fit B-Key or M-Key connectors.
