Calculating Power Use
The total combined wattage for the system configuration must be less than 630 watts. Use the
Excel spreadsheet accompanying your system to calculate the total used by the system. The name
of the file is SRKA4_Power_Budget.xls.
For current and voltage requirements of add-in boards and peripherals, see your vendor's
specifications.
The spreadsheet calculates total power use for a specific server configuration. The spreadsheet
breaks down your system into many categories and automatically calculates power use on the
"Summary" page. Categories include:
Serverboard configuration
®
Intel
chassis
Processors
Memory
PCI
SCSI
Peripherals
System boards
System fans
