Is there any way I can reduce my Pc sleep power consumption?
If I put a socket power meter on the pc while it is in sleep to says it's drawing 27 watts. It is the same for both my pc's. It is around 90 watts while in use.

Is this right? "Short of buying a more expensive power meter to test properly"

If it is 27 watts draw then is there any way to get it down but still retain all the functionality of sleep mode like wake on lan, remote power on, wake to record ect..

Currently the standby cost of the Htpc is about €50 a year.

Both pc's are running windows 7 64bit.
Bios is set to S3 power state I think. But I have tried them all. Sleep always draws up to 30 watts at the socket.

What are the components? Mobo is usually what uses the most power while in sleep.

Other option is to set them to hibernate instead of sleep.

Cheers for the replay.
Components are below. Hibernate will not allow full functionality. Power on by remote or wireless keyboard will not work and pvr con't wake to record I think.

I'm just wondering is 27 watts draw normal for sleep mode?
It would be great if the power meter was not working properly but I don't want to spend €50 to find out.

Sounds a bit on the high side for that build. Are you sure it's actually going in to sleep? It may be just in idle with screen off or something.

I'm sure it is asleep. Definitely.

Out of curiosity have you ever measured your pc for power draw?

This is not a big issue for me but I would love my media centre all the more if I knew it was not costing me €50 a year even if I never used it.

Yeah, though I don't trust the cheap meter I used. The HTPC uses <80W when playing a bluray, and idles at about 30W. It's got a E8400 and integrated graphics. There was a plan to stick a GPU in it, but it's fine for movies.

Idles at 30W! I'm off the charts so. Mine pulls 80w after boot. It rises to 90ish while using Xbmc.
Always 27 in sleep.
