Intel® Server Platform SR6850HW4 TPS

System Overview

qualified technical individuals should access the processor and non-hot-plug I/O areas while the system is energized. Power cords should be removed from the system before accessing non-hot-plug areas.

2.5.11.1System Power Budget

Table 3 shows a summary of the system power budget. The power budget lists each major voltage rail in columns and each major subsystem of the product in rows. The worst-case power per subsystem is listed for each voltage rail. The total power per voltage rail, the power supply specification, and the margin available are shown at the bottom of the table.

Notes:

1.3.3V and 5V are derived from the 12V single switched output of the power supply modules. The 12V column includes the 3.3V and 5V power.

2.3.3Vstby is the standby output of the power supply modules.
