3.3.2. 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 four 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. Table

14 lists PS_ON# signal characteristics.

The power supply shall provide an internal pull-up to TTL high. The power supply shall

also provide de-bounce 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 SELVcompliant.

The power supply shall not latch into a shutdown state when PS_ON# is driven active by

pulses between 10ms to 100ms during the decay of the power rails.

3.3.1. PWR_OK

PWR_OK is a “power good” signal. It should be asserted high by the power supply to

indicate that the +12 VDC, +5VDC, and +3.3VDC outputs are above the under-voltage

thresholds listed in Section 3.2.1 and that sufficient mains energy is stored by the converter

to guarantee continuous power operation within specification for at least the duration

specified in Section 3.2.11, “Voltage Hold-up Time.” Conversely, PWR_OK should be deasserted

to a low state when any of the +12 VDC, +5 VDC, or +3.3 VDC output voltages

falls below its under-voltage threshold, or when mains power has been removed for a time

sufficiently long such that power supply operation cannot be guaranteed beyond the powerdown

warning time.

4.5.1. ATX Main Power Connector

この手の規格物を調べるのに便利なサイトです。

残りの２個だけ。

VFPですが、『+5 volts standby (VSB) is sometimes called volts flea power (VFP). 』

flea power。スタンバイ電源。スイッチを切っても電源コードが刺さっていれば給電される+5V。

VDCはDC(直流)ですね。

URLはダミーです

未説明の箇所を説明します

VPFは

called volts flea power (VFP)で例えば

+5 Vfp (volts　flea power) と表記

しいて訳せばノミ電圧

次にVDCは

Direct Currentは直流だから　直流電圧です
