NGFF M.2 to PCI-E 4X Riser Card

This riser card adapts an M.2 Key M device to a PCI Express x4 slot. It includes an LED voltage indicator to confirm power delivery. The design suits builders adding storage or expansion cards to platforms with spare PCIe lanes. It connects via an internal power cable for stable operation.

Sustained load behaviour

The card maintains a x4 electrical link during extended transfers. The onboard LED provides continuous voltage verification under load. No active cooling is present, so airflow in the chassis manages thermals. Performance scales with the host slot generation and the attached device capabilities.

Questions about this item

Does the LED voltage indicator on this riser card draw noticeable power during continuous operation?

The LED indicator is a low-current feature and adds negligible draw to the 4x PCIe link.

What M.2 drive keying must I already have for this M2 Key M riser card to work?

You need an M.2 drive with Key M pinout; Key B or Key B+M drives will not fit this adapter.
