Re: What do I need to conserve power on my old Linux box?

OK, this model is capable of supplying 865 Watts according to the
manufacturer's specifications.

It better. ;) I only had it for a few months.

You're at 39% of 865 Watts, or about 338 Watts. Multiply that by 24
hours a day, 30 days in a month, divide by 1000 and it seems your
computer is using 243.4 kWh in a month. (Assuming the above is an
"average" load on your UPS.) Check your last electricity bill to see
how much you pay per kWh and you'll know exactly how much your computer
is costing you per month. AFAICT, about 10 cents per kWh is a
reasonable estimate in North America, so I'd guess that running your
computer 24/7 is costing you less than $25/month. That's a pretty small
savings compared to your overall bill, even if you got rid of the
computer entirely.

Ah, thanks! I thought it would be way more than that. If it makes a different, the power
company is Southern California Edison (SCE), not Department of Water and Power (DWP) in east
of Los Angeles, CA.

I forgot to mention that the last UPS status result was with the other machine on (gaming box;
600 watts PSU; probably uses 400-500 at most) that I was using (not gaming -- just surfing the
Web). With the CRT monitor powered off (power button), I lose about 8%:

Also, the only things hooked up to the UPS for battery backups is 17" CRT monitor and two
computers (the Linux box and the other is the gaming/HDTV DVR box).

Thanks for the help. :)
