This article introduces the relevant knowledge of "what is the role of the motherboard type-c interface". In the operation of the actual case, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

The function of the motherboard type-c interface is: it is also the function of data transmission and charging, but most of the computer motherboards will not be equipped with this kind of fast charging protocol chip, so using the computer's Type-C interface to charge is often only 5V voltage, the current is not high, after all, data transmission is the main business, charging is a sideline.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

The first thing to know is that Type-C is only a form of physical interface developed by the USB-IF organization, and USB-IF is the organization that keeps changing the name of USB 3.x. Type-C is a physical specification of the interface rather than a transport protocol. The transport protocol refers to USB 2.0, Universe 3.0, and 3.2 Gen2, which varies with different speeds.

The difference in the use of Tpye-C between mobile phone and motherboard

Type-C took the lead in the early popularity of mobile phones. Compared with the old MICRO USB, Type-C has the same positive and negative plug function as Lightning, so it is well received, and the Type-C interface itself can support high current output and provide fast charging functions such as QC, VOOC, SuperCharge and so on. However, the fast charging protocol needs to be supported by both the mobile phone and the charging head to realize the handshake protocol. By the way, the original data cable of iphone11 is Type-C TO Lightning directly. If you have USB Type-C on your motherboard, you can plug it into it.

In recent years, most of the new motherboards can see the Type-C interface, although it is also data transmission and charging functions, but most of the computer motherboards will not be equipped with this fast charging protocol chip, so using the computer's Type-C interface to charge is often only 5V voltage, the current is not high, after all, data transmission is the main business, charging is a sideline.

Application of motherboard Type-C-- high-speed transmission extension

Different from the fast charging use of mobile phone Type-C, computer Type-C is more often used for high-speed data transmission. For example, the USB 3.2Gen2x2 of 20Gb bandwidth is usually realized by Type-C interface.

Transfer speed using USB Type-C interface (3.2 Gen1)

In addition to USB 3.2Gen2x2, B360, B450, Z390, X570 and other motherboards are also equipped with USB 3.2Gen2 interfaces with a bandwidth of 10G, and there are two interface forms: Type-An and Type-C. Type-C is better than the interface because of its small size and random insertion.

In addition to the USB protocol, Lightning 3 also uses the Type-C interface. It should be noted that Lightning 3 is only a transmission protocol, similar to USB 3.2 Gen2. The Type-C interface between MEG Z490 GODLIKE with lightning 3 protocol and MEG Z490I UNIFY motherboard can provide bandwidth as high as 40Gb, as long as the equipment is lightning 3 and the speed can keep up, so the Type-C of lightning 3 protocol is mainly used to connect external video cards at this stage.

The lightning protocol is supported only if the interface has a lightning target.

In addition, Lightning 3 is, after all, Intel's own protocol, so the current backward compatibility side does not support USB 3.2 Gen2x2, because this protocol mostly comes from third-party chips such as asmedia.
