If you look at the meter next to the router I am using 672 watts, thats the PC, Pioneer Amp, 2 lights, 2 air filters and the fridge compressor was running at the time too.
i thought i might have been misunderstood in how i had originally phrased my reply, that's why i re-wrote it.
i had actually meant to comment on your usage of three separate monitors,
and, apparently, separate PCs as well, all running simultaneously, it would appear. very sorry for the confusion...
