Server Current Usage
Table 36 lists the current usage for both minimally and fully configured servers. You can easily
calculate power usage in the server from the numbers provided. The table is for reference only. It
is not meant to provide the exact current usage in the server; exact values depend on exact
configuration—size and number of processors, DIMMs, hard drives, add-in boards, etc.
