Leaving your computer on...

An old celeron/board/ram running at about 8w? wat? have you actually measured the wattage with anything? even a basic energy monitor would do.

It's a laptop, so much lower power than a PC, he might have even unvolted it, I'm not sure... But he's measured it with his multimeter, can't remember the actual current it was drawing, but once converted into power used over a day, worked out to be about 2p a day.

100W idle for a pc sounds very conservative .... try 160W instead for a modern PC.

Oh don't forget the monitors ! The new monitors these days are great consuming only 30ish W but the old LCDs can use 70->100+W each....

a 2500k and a nvidia 580 at idle has been measured at 75w :D I have a 2500k but a 6950 so i don't know how that holds up.

and i have a LED backlit screen as well.

It's very easy to think that stuff isn't using much juice but as you said, a power meter or an energy monitor will really open your eyes. I know how much my house costs to run at idle and even that is higher than i'd like.

Yeah that's not bad at all but alas we're mostly overclockers here with speedstep firmly switched off. I just wish I could switch overclocking profiles without having to reboot as tbh the overclock is not necessary to have on all the time.

Heh house idle costs - now we're talking :D Have you got some sort of device uploading to google power meter ?

Mine shows a minimum of 100W on 24/7 but when the fridges cycle every few hours it goes up to 300W.

Another advantage of Sandy Bridge is that you can leave it all on :D Mine drops down to 1.6ghz and less than 1v when its idle and jumps to 4.5ghz and 1.31v when its under load. Keeps it efficient while still giving plenty of urge when you need it.

We've just got an Owl energy monitor. It matches up with my bills so it must be accurate enough but I cant get an exact reading on individual kit. I can get a rough estimate though.

IIRC our place costs about 2.8p an hour to run at night when we are asleep and not using anything. Even that is just £245 a year on electric!

My server reads an envi monitor and uploads the readings to google which plots these pretty graphs....

If only I had this when I was averaging 20kwh a day :eek:

turn mine off every night. there is no point having it on, if no one is using it

I suspend to RAM as the machine needs to wake up at 4am, do a backup then go back to sleep
