Power Supply Specification Guidelines Intel® Server Board S2600GZ/GL TPS 11.2 Power Supply DC Output Specification 11.2.1 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. Table 48. Minimum Load Ratings Parameter Min Max. Peak 2, 3 Unit 12V main 0.0 62.0 70.0 A 12Vstby 1 0.0 2.1 2.4 A Notes: 1. 12Vstby must provide 4.0A with two power supplies in parallel. The Fan may start to work when stby current >1.5A 2. Peak combined power for all outputs shall not exceed 850W. 3. 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. 11.2.2 Standby Output The 12VSB 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. Two PSU modules should be able to support 4A standby current. 11.2.3 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. Table 49.
