Abstract: A cable assembly, a signal transmission structure, and an electronic device are provided. The signal transmission structure includes a circuit board (2), a chip (1), and a cable assembly (3). The chip (1) is assembled on one side of the circuit board (2), and the cable assembly (3) is assembled on the other side of the circuit board (2). The cable assembly (3) includes a cable (31), and the circuit board (2) includes a plurality of conductive holes (22). The chip (1) is electrically connected to the cable (31) of the cable assembly (3) by using the conductive hole (22), to transmit a signal of the chip (1) by using the cable (31). In this technical solution, wires do not need to be disposed in a large area inside the circuit board (2).

Abstract: This application discloses a chip power supply system, a chip, a PCB, and a computer device. The chip power supply system includes a first printed circuit board (PCB), a chip, a power controller, and an inductor module. The first PCB includes N vias, first ends of the N vias are located at a top layer of the PCB, and second ends of the N vias are located at a bottom layer of the first PCB. The chip is coupled to the top layer of the first PCB through N power supply contacts and the first ends of the N vias. The inductor module is coupled to the chip through M power supply contacts and the second ends of M vias of the N vias. The power controller is coupled to the inductor module through the first PCB, and the power controller is configured to control the inductor module to supply power to the chip.
