PCIe x1 to 4 PCIe x16 Slots Mining Riser Card, External 4-Port PCIe Multiplier Card USB 3.0 Powered for Bitcoin Mining Rig

This dedicated mining PCIe multiplier riser card expands one motherboard PCIe x1 slot into four available PCIe x16 slots, perfectly solving insufficient expansion ports for multi-GPU mining rigs.

Adopting USB 3.0 auxiliary power supply design, it provides sufficient power output for multiple graphics cards to avoid unstable shutdown and black screen during long-hour mining operation. The external separated layout effectively disperses heat and eliminates space congestion inside the host case.

High-quality shielded PCB circuit lowers signal attenuation and electromagnetic interference, maintaining steady data transmission for multi-card parallel mining. It fits most motherboards and mainstream GPUs widely used in Bitcoin cryptocurrency mining, easy to assemble for DIY multi-GPU mining rig construction.
