PCI for Express 1x to 16x Powered Riser Adapter Card USB 3.0 PCI-E 1 to External 4 GPU Riser Extender Card for Mining Multicolor

Features: brand new and high quality Effectively solve the problem that the motherboard PCI-E interface is not enough, an interface can be extended out of 4. Plug-in board design, directly connected to the motherboard interface without extension cable, and can be fixed to the chassis, greatly improving the stability and reliability. The main control board adopts the PCI-E interface direct power supply mode, no external power line is needed, so that the main control power is not affected by external interference, and the stability is higher. Reducing the number of adapters and patch cords, one wire directly to the interface, effectively reduce interface interference and wire loss, ensure data reliability, and improve work efficiency. The USB connector is gold-plated, which reduces the interference between interfaces and enhances the integrity of the data. It increases the LED flashing when the six LEDs are turned on. Added enhanced compatibility with motherboards and graphics cards, reduced power consumption.
