The BIOS probably makes some of the controls accessible as ACPI objects.
Lots of those are assigned standard numbers. And names like "power button".

The only mention of ACPI in BIOS is 'ACPI sleep state' which is set to
S3.

In device mgr:
'computer' says 'ACPI x86-based PC'
'system devices' says 'ACPI fixed feature button' and 'ACPI power
button'.
The specs on the site below say it's ACPI 2.0a.

You'd need to boot something like the recovery console (or something like
whatever WinPE is), and run the equivalent of Everest, and get a listing
of ACPI objects. And see if you recognize anything out of sorts there.

It's possible the installer isn't using the ACPI object offered by the
BIOS, and there's a lack of communications between the two of them.

Heaven knows what to do about that. This is a modern UEFI motherboard.

Very weird, the whole shebang!

OK, had a look at the manual, and anything useful is gone.

The first review here, mentions a problem with power cutting out
on the board.

"At first I couldn't even get a windows install going on the machine
and I kept getting hard resets out of nowhere. I did a little research
and found that there was an updated bios that effectively limited power
to certain parts of the board. I just wanted to get it working so I
installed the new bios and all was well."

But looking through the BIOS releases on the web page you show,
there's nothing there admitting to any problems. And "kept
getting hard resets" is the exact opposite of your symptoms,
because in your case, you're not getting a reset pulse.

What do you have plugged into the machine ? Any iPod chargers ?
Any unique plug-in cards in the slots ? I'm just looking for
something that might interfere with the logic in the power
cycling section.

I couldn't find anything in the Newegg reviews, that
matched your symptoms.

You should be running a relatively recent BIOS, because when
your board first shipped, there was a danger of the voltage
regulator on board burning up (while extreme overclocking).
It would seem that the later BIOS changes the power limiter
setting (as if it just wasn't set on the early BIOS). F7
is probably safe, as the release notes mention "improved protection mechanism".
I guess terse working comes from their marketing department
("admit to nothing").
