1. The B75 USB-BTC motherboard uses all-solid capacitors to make the motherboard more stable; it supports LGA1155 CPU and uses the B75 chipset to give full play to the CPU performance 2. Innovative design, convert PCIE 1x directly to USB3.0 interface, reduce intermediate transmission links, reduce costs, reduce signal attenuation, and make continuous long-term work more stable. 3. 8-port USB 3.0 interface: With the plug-and-play function, you can instantly experience the data transfer speed 10 faster than USB 2.0 4. The motherboard of B75 mining machine has low power consumption, low calorific value, energy saving and power saving. The actual work done is lasting and rewarding. 5. The motherboard is low in and in expansion interfaces, suitable for the mining industry.
