PCI-E 1 to 4 Riser Card, 16X Slots Riser Card PCI-E Splitter 1X to External 4 PCI-e USB 3.0 Adapter Multiplier Card for ETH Miner GPU Crypto Bitcoin Ethereum Mining Rig

BOSTIN 1x to 16x Riser Card PCI-Express 1 to 4 Slot PCIe USB3.0 Adapter Port Multiplier Miner Card for BTC Bitcoin Miner Mining
PCI-E 1 to 4 riser card brings great extendability，1 interface can be expanded to 4 USB3.0 ports, which effectively solves the problem that the lack of PCIe interface on the motherboard. NOTE: The adapter card cannot be connected to USB devices, since the 4 USB ports transfer PCI-E signals, not USB signals.
The ultra-large imported aluminum alloy heatsink can effectively dissipate excess heat, so that the adapter card is always at a normal temperature, and the operation is more stable.
The main control board adopts the PCI-E interface for direct power supply, without an external power cord, so that the main control board is not interfered by the outside world. 4 USB 3.0 ports can work at the same time, backward compatible with USB 2.0 and USB 1.0, the stability is higher.(The motherboard must be powered off before installation)
Supports PCIE X1 / X4 / X8 / X16 graphics card interface. The interface supports USB3.0 and is backward compatible with USB 2.0/1.0. Support DOS, LINUX, WINXP, WIN7, WIN8, WIN10 and other systems.
