Power supply cluster for personal computer, has power transmission cable connected with main power supply, and low power supply receiving on/off signal, where main power supply receives on/off signal and generates time difference

摘要

The power supply cluster has a power transmission cable (50) exhibiting three ends (51, 52, 53), where the end (51) is electrically connected with a personal computer (10) for receiving an on/off signal of the personal computer. The power transmission cable is connected with a main power supply (20). A low power supply (30) receives the on/off signal, where the low power supply exhibits a signal delay circuit. The main power supply receives the on/off signal, where the main power supply generates a time difference.
