Abstract
A power supply circuit for providing a voltage to a memory slot group with one or more memory slots includes a platform controller hub (PCH), a basic input/output system (BIOS), and a control circuit. The PCH detects whether any of the memory slots are occupied, and notifies the BIOS. If there are any memory slots are occupied, the BIOS enables a general purpose input/output (GPIO) terminal of the PCH. The control circuit controls a power supply to provide or not provide power to the memory slot group based on whether the GPIO terminal of the PCH is enabled.
