My last power problem only occurred rarely at first.  When I was trying 
to write a dual-layer DVD.  Then it increased to inserting a DVD in the 
DL drive.  The single layer drive worked.  Then a strange noise once in 
a while from the case.  Finally ending in one of the raid drives 
crashing.  The +5v rail was at 4.4 volts if I am correct.

With the first power supply, the problems would occur when trying to 
write DVD's but only some times.  Then I would get a system lockup.

As the web camera is drawing power from the USB buss, it may be 
indicating a problem that is only at the edge of being major.
