M.2 MKey PCIE Expansion Adapter Card, ASM1184E Chip M.2 to PCIE X1 4Port USB3.0 Expansion Board for GPU Riser MultiDevice Expansion

This M.2 MKey PCIE expansion adapter card uses ASM1184E port multiplier chip, converting a single M.2 MKey PCIe slot into four independent PCIE X1 channels via USB3.0 ports, ideal for multiGPU riser expansion and solving insufficient motherboard PCIE slot issues.

Equipped with dedicated aluminum heatsink, it effectively dissipates heat for main control chip and prevents overheating during heavyload continuous operation. Highquality fourlayer printed circuit board reduces electromagnetic interference, optimizes impedance matching, maintains stable signal integrity and lowers data packet loss risk.

It features plugandplay functionality without extra driver installation, supporting Windows and Linux systems. It works with PCIE riser cables to connect multiple graphics cards and other PCIE peripheral devices. This adapter only fits M.2 MKey NVMe PCIe slots, not compatible with M.2 BKey or SATA M.2 slots. Please confirm your motherboard M.2 slot key type before purchase. Not for M.2 SATA SSD.
