Notes:
4) 12Vstby must provide 4.0A with two power supplies in parallel. The Fan may start to work when stby
current >1.5A
5) Peak combined power for all outputs shall not exceed 2000W.
6) 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.
11.1.3 Additional Power Supply Specifications and Characteristics
The below specifications and characteristics are applicable to both power supplies unless otherwise specified.
11.1.3.1 Standby Output
The 12VSB output shall be present when an AC input greater than the power supply turn on voltage is applied.
11.1.3.2 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.
