10. 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 1200W and 1600W 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 boards detailed in this document.
10.1
Power Supply DC Output Connector
The server board includes two main power Minifit Jr connectors allowing for power supplies to
attach directly to the server board. The connectors are two sets of 2x3 pin and can be used to
deliver 12amps per pin or 60+Amps total. Note that no over-voltage protective circuits will exist
on the board.

Power Supply DC Output Specification
10.2.1
Output Power/Currents
The following tables define the minimum power and current ratings. The power supply must
meet both static and dynamic voltage regulation requirements for all conditions.

Notes:
1. Peak combined power for all outputs shall not exceed 800W.
2. Length of time peak power can be supported is based on thermal sensor and assertion of the SMBAlert#
signal. Minimum peak power duration shall be 20 seconds without asserting the SMBAlert# signal at
maximum operating temperature.
10.2.2
Standby Output
The 5VSB output shall be present when an AC input greater than the power supply turn on
voltage is applied. There should be load sharing in the standby rail.
10.2.3
Voltage Regulation
The power supply output voltages must stay within the following voltage limits when operating at
steady state and dynamic loading conditions.
These limits include the peak-peak ripple/noise.
These shall be measured at the output connectors.
