    PCIe 4.0 x16 to Dual x8 Bifurcation Riser Kit with 2 Expansion Cards

    • One Slot, Two x8 Connections: Expand a compatible PCIe x16 slot into two x8 links for graphics cards or PCIe-to-M.2 NVMe adapters; your motherboard, CPU and selected slot must support x8/x8 bifurcation, with the mode enabled in BIOS
    • Flexible Card Placement: Two 75cm (29.53-inch) SlimSAS SFF-8654 8i cables let you position expansion boards beyond the motherboard's fixed slot spacing; plan card placement and cable routing for custom workstations and open test benches
    • PCIe 4.0 Connection Design: Designed for up to PCIe 4.0 x8 per link, with 16 GT/s per lane; each expansion board has a physical x16 slot with up to x8 electrical lanes; actual link speed and width depend on your system and installed device
    • Separate Power Connections: Each expansion board requires 6-pin PCIe auxiliary power; graphics cards with power sockets also require suitable PSU cables; for x8/x8 operation, connect each SlimSAS cable to Slot 1 on its expansion board

    The PCIe Bifurcation Riser Card x16 to Dual x8 is an essential expansion solution for users looking to maximize the potential of their motherboard's PCIe slots. This riser card splits a single x16 PCIe slot into two independent x8 slots, allowing you to run two separate PCIe devices simultaneously from a single slot. It is ideal for multi-GPU setups, NVMe storage expansion, or adding additional high-speed peripherals to your system. The bifurcation design ensures that bandwidth is efficiently distributed between both x8 slots, maintaining strong performance for demanding workloads. Compatible with motherboards that support PCIe bifurcation settings in the BIOS, this riser card is a practical upgrade for workstations, servers, and high-performance computing builds.

    Whether you are a content creator, data professional, or PC enthusiast, this card helps you get more out of your existing hardware without requiring additional motherboard slots. Please verify your motherboard supports x8/x8 bifurcation mode before purchasing.
