Motherboard and electronic device using the same

摘要

An electronic device proof against surge currents arising from hot-swapping components comprises a platform controller hub chip, an electronic component, a serial peripheral interface, and a power supply unit. The power supply unit comprises a power supply and a Zener diode, the power supply outputs a first voltage to the Zener diode, the diode converts the received first voltage to a second voltage and outputs the second voltage to one or more electronic components and the platform controller chip.
