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

For measuring exactly you should first see work done by guys from xbitlabs[1] 
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 CPU 
or MB?
