This PCIe bifurcation expansion card divides one motherboard PCIe x16 slot into two separate x8 slots simultaneously. The 20mm slot interval matches mainstream case installation requirements perfectly.

The onboard 4Pin power interface plus included dedicated power cable ensures sufficient power delivery for high-load expansion devices. With locking GEN4 connectors and EMI suppression design, it supports long-term stable operation for workstations, servers and multi-device expansion rigs.

Note: Motherboard must support PCIe bifurcation function and enable x8×8 split mode in BIOS.
