13. Power Supply Specification Guidelines
This section provides power supply specification guidelines recommended for providing the specified server
platform with stable operating power requirements.
Note : The power supply data provided in this section is for reference purposes only. It reflects Intel’s own DC
power out requirements for a 750W power supply as used in an Intel designed 2U server platform. The
intent of this section is to provide customers with a guide to assist in defining and/or selecting a power
supply for custom server platform designs that utilize the server board detailed in this document.
13.1 Power Supply DC Output Connector
The server board includes two main power slot connectors allowing for power supplies to attach directly to
the server board. Power supplies must utilize a card edge output connection for power and signal that is
compatible with a 2x25 Power Card Edge connector (equivalent to 2x25 pin configuration of the FCI power
card connector 10035388-102LF).
