The graphics card power supply uses 4 solid capacitors to make the graphics card power supply more stable and safe. The adapter card has a 6PIN interface 12V to strengthen the DC-DC power supply, so that the power supply of the graphics card is from the motherboard, thereby reducing the burden on the motherboard when multiple graphics cards are connected. The graphics card slot adopts the connector, which makes the contact between the graphics card and the connector better. The PCI-E connector adopts multi-layer shielded wire, which can be connected to 3 Meter without attenuating the signal. The USB wire is soft and stable, the wiring is convenient, and the graphics card can be placed at will. The slot is equipped with a fixed buckle, which is more convenient to remove the graphics card and fix the graphics card, and the graphics card will not fall off from the slot. The wire uses the wire drawn by the most stable manufacturer currently in use ( is secret) to the integrity of the signal. The USB cable on the market has not woven the shielding net, and the quality is quite poor, so it will be very unstable, please be aware. (Not all wires can be used) The power cord adopts pure copper wire, which avoids wire burning during work.
