9.2.1 Processor Power Support
The server board supports the Thermal Design Power (TDP) guideline for Intel
®
Xeon
®
processors. The Flexible Motherboard Guidelines (FMB) has also been followed to help
determine the suggested thermal and current design values for anticipating future processor
needs. The following table provides maximum values for Icc, TDP power, and T

9.3 Power Supply Output Requirements
This section is for reference purposes only. The intent is to provide guidance to system
designers to determine a power supply for use with this server board. This section specifies the
power supply requirements Intel
®
used to develop a power supply for the Intel
®
Server System
SR1600UR.
The combined power of all outputs does not exceed the rated output power of the power supply.
The power supply meets both static and dynamic voltage regulation requirements for the
minimum loading conditions.

Notes:
1. Maximum continuous total DC output power should not exceed 600 W.
2. Peak load on the combined 12 V output should not exceed 49 A.
3. Maximum continuous load on the combined 12 V output should not exceed 44 A.
4. Peak total DC output power should not exceed 650 W.
5. Peak power and current loading are supported for a minimum of 12 seconds.
6. Combined 3.3 V and 5 V power should not exceed 150 W.
9.3.1 Grounding
The grounds of the power supply output connector pins provide the power return path. The
output connector ground pins are connected to safety ground (power supply enclosure). This
grounding is designed to ensure passing the maximum allowed common mode noise levels.
