PCI-E X1 to 4 PCI-E X16 Expansion Riser Card, 1 to 4 Port PCI Express Switch Multiplier Hub with 6Pin SATA Power Supply, PCIe Splitter Adapter for BTC Mining Rig GPU Expansion

This PCI-E X1 to 4 PCI-E X16 expansion multiplier riser card is specially developed for cryptocurrency mining rig assembly and multi-graphics card expansion projects. It takes up only one motherboard PCI-E X1 slot and expands it to 4 full-speed PCI-E X16 slots, allowing users to connect up to four GPUs simultaneously to maximize computing performance for mining operations.

Designed with a 6Pin SATA power interface, it can directly draw sufficient power from the computer power supply unit, effectively avoiding insufficient power supply and unstable operation caused by long-term high-load working of multiple graphics cards. The built-in optimized signal amplification circuit greatly reduces electromagnetic interference and data packet loss during high-speed transmission, guaranteeing continuous and reliable running of the mining system.

The PCB board adopts high-quality material and rigorous welding craftsmanship, with reasonable component layout to facilitate air circulation and heat dissipation inside the mining chassis. Simple plug-and-play installation requires no complicated driver setup, perfectly compatible with mainstream motherboards and mining graphics cards. Besides BTC mining rigs, it can also be used for video rendering workstations, industrial host hardware expansion and other scenarios that demand multiple PCIe devices connection.
