Power Requirements
Your system requires a clean, steady power source for reliable performance of the high frequency CPU on
the product, 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 product is designed to operate with at least a 200 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 - 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 Tolerances
