what is needed pwr_good in BP?

I quietly made laboratory power supply, 230 from an old jacket. Just now faced a problem: I don't know what to do with the power good wire in the PSU(oranzhevy). Fluent gugleniya did not answer. So where it to pick up and generally dlaczego is it needed?

Need to report a fed device that stress is established and you can start working.
In a makeshift laboratory BP is likely to leave hanging in the air.
thank you) - maeve_Mant commented on October 8th 19 at 02:24

the value of the PWRGOOD signal (32) is sampled (step 42). In the case that the value is "0" (indicating that the system is in shutdown state), no operation is required and the system reverts to idle state (44), awaiting an event. If, on the other hand, the value in step (42) is "1", indicating that the poweris on, then a PWRBTN# signal ("0") is triggered (43) and fed to the ACPI module ((26) in FIG. 2). The latter, depending upon its operational state, will trigger an ONCTL# signal de-asserted. In the common case when the system is functional this will bedone via a call to the CPU (21) that will handle the shutdown process and will give the proper turn-off command. When the system is not functional this will be done by the ACPI state machine directly after 4-seconds.

Although, due to the fact that this patent, I'm not sure if this is standard behavior for acpi - maeve_Mant commented on October 8th 19 at 02:26
to use acpi to PSU — not in my plans, definitely) - Ericka.Kling commented on October 8th 19 at 02:29
Oh, my apologies, I confused acpi and ATX.
That's just your case.

Here here well described the principle of use power good.
thanks, it was interesting to read) - maeve_Mant commented on October 8th 19 at 02:28

It's just a "duty" to 5V on the motherboard. When there is 220 on the PSU, at the orange wire should be 5 volts.
these are not just 5 volts to the mother. duty is 5v_stnb (brown) - maeve_Mant commented on October 8th 19 at 02:30
