The USB 5P motherboard's 3A high current fast charging function computer connector interface mainly increases the output of+5V and+5VSB. However, the+5VSB output of the old power supply on the author's computer is the same as the office computer power supply, and the+5V output is also greater than the office computer power supply output, so it can only be related to the motherboard. After carefully reviewing the motherboard manual, it was found that the motherboard supports keyboard startup and other functions. The keyboard, mouse, USB interface, etc. all use+5VSB output power supply, but the office machines do not support these functions. At this point, the author suddenly realized that there are too many devices that need+5VSB output power supply, which leads to insufficient+5VSB output. As a result, the power supply of the Portable storage device that needs a large current is insufficient, and the power demand of the Portable storage device cannot be normal. However, the+5VSB output of the power supply cannot meet the demand, so we have to think about the+5V output of the power supply. Providing it directly to the USB interface for use, the integrated USB interface circuit on the motherboard is complex and difficult to modify. The front USB interface on the chassis is connected to the motherboard through a row plug, providing the possibility for modification. Just unplug the VCC and ground wire in the USB connector of the chassis from the motherboard pin and connect them to the red wire (+5V) and black wire (ground wire) in the spare power output 4PIN plug. USB 2.0 A female high current 5P female sinking plate short body 11.0mm SMT, widely used in consumer electronics products such as digital cameras and tablets. The product has a complete range of products, reasonable prices, strong corporate strength, credit worthiness, contract compliance, and product quality assurance. Welcome to inquire about the soldering method of this product, which is 5Pin pin. The front of the hardware shell is equipped with double fixed patch feet. In terms of material used in the product: the plastic is environmentally friendly and high-temperature resistant, the hardware surface is electroplated with bright nickel, the 5Pin pin terminal base material is high conductivity copper alloy, and the surface is electroplated with tin. Copper/iron case USB with four harpoon pin sockets that can be hot swapped. This allows users to use external devices without repeating the action of "turning off and connecting the parallel or serial cable before turning on". Instead, they can directly plug in the USB cable while the computer is working.
