Intel® Server Boards S5000PSL and S5000XSL TPS

Design and Environmental Specifications

8.2.1Processor 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 TCASE for the dual core Intel® Xeon® processor 5000 sequence family.

Note: These values are for reference only. The Dual-Core Intel® Xeon®) processor 5000 sequence Datasheet contains the actual specifications for the processor. If the values found in the Dual-Core Intel(r) Xeon(r) processor 5000 sequence Datasheet are different than those published here, the Dual-Core Intel(r) Xeon(r) processor 5000 sequence Datasheet values will supersede these, and should be used.

8.3Power 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 shall 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.
