It would have nothing to do with your equipment, or even anything
within your control if the line voltage got too low. As for the PSUs
in your equipment, I've discovered that even "expensive" ones can be
crap, and some cheapies are actually pretty good. Manufacturers just
grab whatever they can get cheaply, knowing that most consumers would
be hard put to even know what a DC power supply was, much less shop
intelligently for one. Folks on this list are better-educated than
most on this subject, but capture cards put higher-than-average loads
on the 12-volt rails so the PSUs are not being used in a "common"
configuration.
Do you have something like a "Kill-a-Watt"? That's one of the best
investments I ever made IMHO. Even a VOM or DMM can at least measure
line voltage, be careful with the probes though.
