Green printed circuit board with four U.2 SFF-8643 connectors and a PCIe 3.0 x16 edge connector

SMUGDESK

SMUGDESK PCIe 3.0 x16 to U.2 SFF-8643 NVMe 4-Port Adapter

SKU CH-JH04-3P3HJ

Adds four U.2 SFF-8643 NVMe ports to a PCIe 3.0 x16 slot for high-speed storage expansion

  • Converts one PCIe 3.0 x16 slot into four U.2 NVMe ports
  • PCIe 3.0 standard delivers high-speed data transmission for demanding workloads
  • Fits both PCIe x8 and x16 slots for broad platform compatibility
  • Available in 1, 2 or 4-port versions to match expansion requirements
  • Simple installation enables quick storage upgrades in servers and workstations

Four-Port NVMe Expansion

This SMUGDESK adapter converts a single PCIe 3.0 x16 slot into four U.2 SFF-8643 ports for NVMe SSDs. It is designed for servers and workstations that need additional high-speed storage bays without occupying extra expansion slots.

SFF-8643 Connectivity

The card fits standard PCIe x8 or x16 slots and provides four SFF-8643 connectors for direct U.2 drive attachment. Each port carries a full PCIe 3.0 link, so cable routing and drive placement remain flexible inside dense chassis.

Slot and Cabling Check

Verify the motherboard has a free x8 or x16 slot wired for PCIe 3.0 and enough physical clearance for the card plus four U.2 cables. Buyers needing fewer ports should select the one- or two-port variant instead.
