PCIe 4.0 x16 to x8x8 Bifurcation Split Expansion Card, Gen4 1-to-2 PCI-E Splitter with 20mm Slot Spacing, Equipped with Premium CPU 4Pin Aux Power Cable for Dual GPU, Capture & Network Cards
- Full PCIe 4.0 x8x8 Bifurcation Function
- Split one x16 PCIe lane into two independent x8 full-speed channels, fully compliant with PCIe 4.0 standard and backward compatible with PCIe 3.0. Zero bandwidth loss when two devices work simultaneously.
- 20mm Wide Slot Spacing Design
- 20mm gap between two PCIe slots provides ample clearance, preventing physical collision between large GPU heatsinks, cooling fans and metal brackets when installing dual full-size expansion cards.
- Matching High-Quality CPU 4Pin Aux Power Cable Included
- Comes with upgraded dedicated 4Pin power cable as standard accessory. It supplies stable extra 12V power from PSU, effectively solving voltage drop, black screen and device offline issues under dual high-load PCIe devices.
- Independent Clock Split IC & Durable Hardware
- Built-in dedicated clock control chip ensures stable dual-channel signal transmission; thick gold-plated contacts reduce oxidation and signal attenuation for 24/7 continuous heavy-duty operation, with power LED to display working state.
- Wide Compatibility with Multiple PCIe Devices
- Supports dual gaming/rendering GPUs, 4K/8K video capture cards, 10G/25G network adapters, RAID controllers and all x8/x16 PCIe peripherals, suitable for workstations, servers and multi-GPU mining rigs.

This PCIe 4.0 x16 bifurcation split expansion card converts one motherboard PCIe x16 slot into two separate x8 expansion ports, perfectly making up for the shortage of native PCIe slots on editing workstations, rack servers and rendering rigs.
It strictly follows PCI Express 4.0 protocol and supports downward adaptation to PCIe 3.0 hardware. Important note: Users must enable PCIe bifurcation function and set lane split mode to x8x8 in motherboard BIOS to unlock full dual x8 bandwidth performance.
The dual PCIe slots adopt optimized 20mm center spacing, which avoids mutual extrusion of large cooling radiators of two graphics cards during installation. Unlike ordinary split cards without supporting wires, this product is pre-equipped with an upgraded high-spec CPU 4Pin auxiliary power cable. The independent power supply channel can make up for the insufficient 75W power supply of a single motherboard PCIe slot, greatly improving the stability of dual high-power equipment running at full load.
The built-in professional split IC isolates two groups of signal channels to avoid bandwidth competition and signal interference. Gold-plated fingers lower contact resistance for long-term uninterrupted operation, and the onboard indicator LED allows users to quickly check power status.
Common application scenarios include dual-GPU 3D rendering workstations, multi-channel video recording hosts, multi-port network servers and industrial control expansion equipment. After finishing BIOS bifurcation configuration, it can be put into use directly with the matched 4Pin cable, a complete high-performance PCIe lane expansion kit for hardware enthusiasts, content creators and server integrators.
