I mostly agree with what you're saying but I figure I'll thow a few logs in the fire; except: Most US power supplies are ~50% efficient, so you can draw up to 700 KW (mine says 750 KVA), but the power factor for these puppies is terrible (.6-.8 like another poster said), so the "real" consumption may not be as visible... > Times 30 days = about $33 /month. << Worst Case > ~5.00 <(ya, I deleted this bit prematurely) << Best Case The real number should be in between -- I don't think you can count a myth box that pegs the CPU as idle most of the time... Hrm... this might be my excuse to get a PVR x50 card (~20/mo savings, payback in 5-6 months... not too shabby). -Thor Johnson _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
