4.6. PS_ ON#
PS_ON# is an active-low, TTL-compatible signal that allows a motherboard to remotely control the
power supply in conjunction with features such as soft on/off, Wake on LAN+, or wake-on-modem.
When PS_ON# is pulled to TTL low, the power supply should turn on the five main DC output rails:
+12VDC,+5VDC,+3.3VDC,-5VDC,and –12VDC. When PS_ON# is pulled to TTL high or open-
circuited, the DC output rails should not deliver current and should be held at zero potential with
respect to ground. PS_ON# has no effect on the +5VSB output, which is always enabled whenever
the AC power is present. Table 15 lists PS_ON# signal characteristics.
The power supply shall provide an internal pull-up to TTL high. The power supply shall also
provide debounce circuitry on PS_ON# to prevent it from oscillating on/off at startup when
activated by a mechanical switch. The DC output enable circuitry must be SELV-compliant.
