PCIe 4.0 x16 to x8x8 Bifurcation 1-to-2 Split Expansion Card, Gen4 PCI-E Splitter with 20mm Slot Spacing & CPU 4Pin Aux Power Port for GPU Capture Network Cards

This PCIe 4.0 x16 bifurcation split card converts a single motherboard PCIe x16 slot into two separate x8 expansion ports, solving the problem of insufficient native PCIe slots on editing workstations, rack servers and multi-GPU rigs.

Compliant with full PCI Express 4.0 specification and downward compatible with PCIe 3.0 hardware. Important reminder: You need to enable PCIe bifurcation and set lane split mode to x8x8 in motherboard BIOS to activate dual x8 full-speed performance.

Dual PCIe slots adopt optimized 20mm center spacing design, effectively preventing heatsink interference during dual graphics card installation. Equipped with CPU 4Pin auxiliary power port to draw stable power from PSU, greatly lowering system crash risks caused by limited power supply of motherboard PCIe slot itself.

Professional split clock IC separates dual-channel signals to avoid bandwidth competition during concurrent working. Thick gold-plated fingers cut contact resistance and signal loss for long-time heavy-duty use; onboard LED lets you quickly judge working status at a glance.

Widely used in dual-GPU rendering stations, multi-channel video recording hosts, multi-port network servers and industrial control expansion equipment. After completing BIOS bifurcation settings, it can be used directly without extra complicated wiring, a high-performance PCIe lane expansion accessory for hardware builders and content creators.
