I don't know if any tool will let you get how much power your drives are us=
ing=20
but for monitoring voltage you should find something in ports. It can tell=
=20
only if the voltage you get from PSU is rather OK or not.

=46or measuring exactly you should first see work done by guys from xbitlab=
s[1]=20
They are writing how they measure that but not in very simple way ;)

Are you sure that those reboots aren't because of too high temperature on C=
PU=20
or MB?
