SRPL8 Server System Product Guide 193
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.
