8.3.1 Processor Power Support
The server board supports the Thermal Design Point (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
CASE
for the
Intel
®
Xeon
®
processor 5000 sequence family.

Note: These values are for reference only. The Intel
®
Xeon
®
Processor 5000 Sequence
Datasheet contains the actual specifications for the processor. If the values found in the Intel
®
Xeon
®
Processor 5000 Sequence Datasheet are different than those published here, the Intel
®
Xeon
®
Processor 5000 Sequence Datasheet values will supersede these, and should be used.
8.4 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 its 5U server system.
The combined power of all outputs should not exceed the rated output power of the power
supply. The power supply must meet both static and dynamic voltage regulation requirements
for the minimum loading conditions.
Table 43. 550-W Load Ratings
Voltage Minimum Continuous Maximum Continuous Peak
+3.3 V 1.5 A 24 A
+5 V 1.0 A 24 A
+12 V1 0.5 A 16 A 18 A
+12 V2 0.5 A 16 A 18 A
+12 V3 0.5 A 14 A
+12 V4 0.5 A 8 A 13 A
-12 V 0 A 0.5 A
+5 VSB 0.1 A 3.0 A 3.5 A
Notes:
1. Maximum continuous total DC output power should not exceed 550 W.
2. Maximum continuous combined load on +3.3 VDC and +5 VDC outputs should not exceed
140W.
3. Maximum peak total DC output power should not exceed 660W.
4. Peak power and current loading should be supported for a minimum of 12 seconds.
5. Maximum combined current for the 12 V outputs should be 41 A.
6. Peak current for the combined 12 V outputs should be 50A.
