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 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. (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.
