Shenzhen Lianrui Information Technology LRFC6911N 1 Port SFF-8643 to PCIe x16 Slot Adapter

SKU CH-HRGQ-NW837 MPN LRFC6911N

Connects a single SFF-8643 host port to one PCIe x16 slot running at x4 bandwidth with a 15-pin power socket

  • TypeController Card
  • Expands PCIe connectivity via one SFF-8643 Mini-SAS HD link
  • Delivers x4 lane bandwidth through a full-length PCIe x16 slot
  • Powers installed cards reliably with a standard 15-pin SATA power connector
  • Supports network, graphics and video add-in cards in the x16 slot
  • Enables flexible server and terminal expansion using the LRFC6911N adapter

Connection Interface

The LRFC6911N adapter bridges a single SFF-8643 Mini-SAS HD receptacle to a physical PCIe x16 slot operating at x4 bandwidth. It is designed for system integrators who need to extend a PCIe link from a host adapter or switch card to a standard expansion slot in servers or specialised chassis.

Target Builder

This card suits engineers adding GPUs, network controllers or capture cards to platforms that expose only SFF-8643 uplinks. Builders whose host provides native PCIe slots, U.2 bays or M.2 connectors should look elsewhere because the adapter adds latency and requires a compatible upstream switch or HBA.

Sustained Operation

A 15-pin SATA power socket feeds the slot directly, delivering auxiliary current for devices that draw more than the bus supplies. The x4 electrical link caps throughput at four lanes, so high-bandwidth accelerators will plateau at that ceiling during prolonged compute or storage workloads.

商品問答

Do I need a PCIe switch host card with an SFF-8643 port to use this LRFC6911N adapter?

Yes, the adapter connects to a PCIe switch host card through its single SFF-8643 receptacle, which then provides the x16 slot for your expansion card.

Will a graphics card run at full x16 speed when installed in this adapter's slot?

The slot is physically x16 but operates at x4 bandwidth, so a graphics card will function but with reduced throughput compared to a native x16 motherboard slot.

How can I confirm the adapter is powered correctly after connecting the SATA 7 Pin connector?

The 15 pin power socket on the board receives power from the SATA connector; if your installed expansion card initializes and appears in the system, power delivery is working.
