The 8-pin power interface of the graphics card is an 8-pin module power interface consisting of 3 12V power lines and 5 ground wires. The drive current does not exceed 4.167A and the power does not exceed 150W.

It is an improved version of the +12v4pin interface, providing dual 12V power supply and energy consumption support for high-power multi-core series processors. From a working principle, these two interfaces have the same functionality.

If the motherboard has a 4-pin connector and the power supply provides an 8-pin connector, just connect according to the anti-insertion and anti-reversal design. If the motherboard provides an 8-pin connector and the power supply only has a 4-pin connector, it can also be mounted closer to the right for backward compatibility.

It should also be noted that this slightly flat 8pin interface can only be used on the motherboard, not the power supply of the graphics card, which is completely different from the 8pin interface used by high-end graphics cards.

Generally speaking, the power of the graphics card comes from the motherboard slot. However, as the power consumption of the graphics card increases, the graphics card also requires additional auxiliary power supply to work stably. With the changes in the core of the graphics card, the power interface has various forms: D-type 4PIN power supply interface, 8PIN power supply interface, dual 6PIN power supply interface and 8+6PIN interface.

Extended information:

The interface type refers to the interface type used to connect the video card to the motherboard. The interface of the graphics card determines the maximum bandwidth of data transmission between the graphics card and the system, that is, the maximum amount of data that can be transmitted in one instant.

Different interfaces determine whether the motherboard can use this graphics card. Only if there are corresponding interfaces on the motherboard, different interfaces can bring different performance to the graphics card.

The large 4Pin interface is a common d interface, that is, the traditional 4Pin power interface, which is the same interface used by hard drives. Most external devices use this power connector. It is basically a product of the AGP era. Because the motherboard cannot meet the power supply requirements of high-end graphics cards, this interface appears on the graphics card.

The small 4Pin auxiliary power interface is the same as the floppy drive power interface. It is an interface improved by graphics card manufacturers to solve the problem of too large D-type graphics card interface. Fortunately most power supplies provide this interface.
