M3A Behaviour

I just built a new rig with the M3A board from Asus. I chose it because I
wanted Hypertransport 3.0, but did not need SLI or crossfire capabilities.
One particularly strange thing about this board is what happens every time
you make a change in BIOS setup. After you choose save and exit, the board
immediately powers down for about 4 seconds, and then restarts. I have
never seen a board do this before, and wondered if it was normal? It
doesn't say anything about this in the manual, and no reviews I can find
mention it either, I'm concerned that my 500 watt power supply might not be
strong enough for this build, and is causing this. Anyone have any insight
to lend to this?

I have the same issue here, also using the M3A board. As far as I know,
it does not hurt jour system.

I have a P5B - Plus MB and it does the same thing. It's the way the
BIOS works, as you say, when changes are made in the BIOS and/or when
powering off completely (PSU off also) and powering back up.

Thanks for responding. It is strange behavior (to me) for an MB to power
cycle because of a BIOS change, but it does seem to be normal for this
board.
I did upgrade my power supply from 550 to 800 Watts to ensure everything was
getting enough power, and the system does run better and cooler with the new
supply. This board is a lot hungrier for power than my M2N that it
replaced, but that is possibly due to HyperTransport version 3 as opposed to
version 1.
