Power Supply Requirements
A clean and stable power supply is required to ensure reliable operation due to the high
CPU clock frequencies used on the board. The quality of the power supply is even
more important.
To achieve the maximum performance from such high-speed CPUs, ensure that the DC
power supply remains within the range 4.75V to 5.25V.
Power Consumption
In its standard configuration, the CPU board is designed to operate with at least a
200W power supply. If a high-load configuration is used, a power supply with
greater than 200W capacity is required. The power supply must satisfy the following
requirements.
- Power supply rise time: 2ms to 20ms
- Minimum delay in response to a reset on a good-quality power
supply: 100ms
- Minimum power supply disconnect warning: 1ms
- The 3.3V output must reach the minimum fluctuation ratio level
within 20ms of the +5V output reaching its minimum fluctuation
ratio level.
The table below lists the DC voltage tolerances for the power supply.
