PCI-E 1X to 2 PCI-E Riser Card, PCIe Multiplier Expansion Card with Dual USB 3.0 Ports, External Extension Adapter for GPU Crypto Mining Rig

This PCI-E 1 to 2 riser multiplier card is specially designed for crypto mining rigs to solve the problem of insufficient motherboard PCI-E slots. It converts a single PCI-E x1 slot into two separate PCI-E signal channels, allowing you to connect two GPU risers via external USB 3.0 extension cables and install more graphics cards to boost mining hash rate.

Equipped with two USB 3.0 ports dedicated to transmit PCI-E signals (not for common USB peripherals), it supports flexible GPU placement and better airflow inside open-air mining frames. The oversized aluminum heat sink efficiently dissipates heat generated during 24/7 continuous mining, avoiding overheating crashes and signal drops.

Adopting mature main control chip, the card draws power directly from the PCI-E bus without extra SATA/Molex power wiring, simplifying rig wiring and reducing circuit interference. It fits all standard PCIe x1, x4, x8, x16 motherboard slots and works perfectly with Windows 7/8/10/11 and Linux mining operating systems.

Comes with a full-height metal mounting bracket for secure installation inside PC cases. Gold-plated contact pins reduce signal loss and extend service life, an essential expansion accessory for miners building multi-GPU mining rigs.

Note: The two onboard USB 3.0 ports only transmit PCI-E signals; do not plug ordinary USB flash drives or peripherals to avoid hardware damage.
