PSON# Required Signal Characteristic 13.2.7.2 PWOK (Power OK) Output Signal PWOK is a power OK signal and will be pulled HIGH by the power supply to indicate that all the outputs are within the regulation limits of the power supply. When any output voltage falls below regulation limits or when AC power has been removed for a time sufficiently long so that power supply operation is no longer guaranteed, PWOK will be de-asserted to a LOW state. Refer to Figure 55 for a representation of the timing characteristics of PWOK. The start of the PWOK delay time shall inhibited as long as any power supply output is in current limit. Table 89. PWOK Signal Characteristics PWOK = High PWOK = Low Signal Type Logic level low voltage, Isink=4mA Logic level high voltage, Isource=200A Sink current, PWOK = low Source current, PWOK = high PWOK delay: Tpwok_on PWOK rise and fall time Power down delay: T pwok_off Open collector/drain output from power supply.

This power supply has 2 outputs; 12V and 12V standby. The AC input is auto ranging and power factor corrected. 13.3.1 Mechanical Overview The physical size of the power supply enclosure is 39/40mm x 74mm x 185mm. The power supply contains a single 40mm fan. The power supply has a card edge output that interfaces Revision 1.2 141 Intel order number G26942-003
