Power Requirements
Your system requires a clean, steady power source for reliable performance of the high frequency CPU on
the SPC-8450-LVA , 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 card 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:
