10.1 Intel® Server Board SE7221BK1-E Power Budget

The following table shows the power consumed on each supply line for the SE7221BK1-E baseboard that is configured with one processor (128W max). This configuration includes four 1 GB DDR2 DIMMs stacked burst at 70% max. The numbers provided in the table should be used for reference purposes only. Different hardware configurations will produce different numbers. The numbers in the table reflect a common usage model operating at a higher than average stress levels.
