Apparatuses, systems, and methods are disclosed for techniques for supporting multiple PSUs. An apparatus includes a motherboard and a switch coupled to the motherboard for controlling power supply to the motherboard from a PSU. In response to detecting a single-rail PSU connected to the motherboard, the switch is closed in response to a power-on signal to provide main power from the PSU to the motherboard and the switch is opened in response to a standby signal to cut main power from the PSU to the motherboard. In response to detecting a dual-rail PSU connected to the motherboard, the switch is opened and bypassed such that main power to the motherboard is controlled by the PSU via transmission of the power-on signal and the standby signal.
