Power Management Features
- Support both ACPI (Advanced Configuration and Power Interface) and legacy (APM) power
management.
- ACPI v2.0 compliant
- APM v1.2 compliant
- PCI bus clock run, Power Management Enable (PME) control, all with hardware automatic wake-up.
- Multiple suspend power plane controls and suspend status indicators
- Normal, doze, sleep, suspend and conserve modes
- Global and local device power control
Power Requirements
Your system requires a clean, steady power source for reliable performance of the high frequency CPU,
the quality of the power supply is even more important. For the best performance makes sure your
power supply provides a range of 4.75 volts minimum to 5.25 volts maximum DC power source.
Power Consumption
For typical configurations, the CPU board is designed to operate with at least a 250 W power supply. A
higher-wattage power supply should be used for heavily-loaded configurations. The power supply must
meet the following requirements:
- Rise time for power supply: 2 ms - 20 ms
- Minimum delay for reset to Power Good: 100 ms
- Minimum Power down warning: 1 ms
The following table lists the power supply’s tolerances for DC voltages:
Table 2.2. DC voltage tolerance
DC Voltage Acceptable Tolerance
+5V ± 5%
+5VSB (Standby) ± 5%
+12V(For fan) ± 5%
