ASRock MB implements AMD PSI (Power State Indicator) spec, which is a function for AM2+ (Phenom CPU) platform to improve energy efficiency by disabling extra phases when CPU is at light loading.

Power phase status – ASRock Intelligent Energy Saver (IES) is activated to save power energy and lift power efficiency. When CPU is at heavy loading, the system will be running with 4 power phases and when CPU is at light loading or idle, the system will be running with 2 power phases.

Power Saving – You can easily find out how much power you have saved in total or in a specific duration by using ASRock IES system.

CPU power information – This allows you to easily view the CPU Voltage, CPU Frequency or CPU power consumption status.
