Specifications: The graphics card power supply uses 4 solid capacitors (4Pin are 3 capacitors), which makes the graphics card power supply more stable and safe. The riser card has a 6Pin connector or a large 4Pin connector to make the card power supply independent from the motherboard, thus reducing the burden on the motherboard when connecting multiple cards. The right slot of the slot leads to the wiring of the 2U chassis. The graphics card slot adopts the original imported connector, and the graphics card and the connector are in better contact. PCI-E connector uses multi-layer shielded wire, the longest can be connected to 3 meters without attenuating the signal. The USB cable is soft and stable, the cable is convenient, and the graphics card can be placed at will. The slot is equipped with a fixed clip, which makes it easier to remove the graphics card and fix the graphics card. The graphics card will not fall out of the slot. The power line adopts pure copper wire, which avoids burning wire during mining.
