2X PCI-E 4.0 X16 1 to 2 Gen4 Split Card PCIe-Bifurcation X16 to X8X8 with 20mm Spaced Slots CPU4P(4 Pin )

High-performance PCIe expansion splitter that turns one PCI-E 4.0 x16 slot into two x8 outputs (X16 to X8X8), compatible with both Gen4 and Gen3 devices. PCIE X16 full bandwidth 4.0, GEN4 protocol, compatible with gen3/gen4. Includes a CPU4P auxiliary power supply port (4-pin) to ensure stable power delivery. Slot spacing is 2cm to fit systems with 20mm separation between cards, and it supports the use of PCIe extension cable adapters. The board uses a gold finger sinking process with increased gold thickness of 5U for improved contact reliability. Built-in clock-splitting IC and a power-on LED indicator are provided. Note: motherboard BIOS must support changing the PCIe operating mode to X8X8. The unit adopts GEN4 connectors with dust plugs and snap locks for secure, dust-resistant connections.
