Though I would put this up on a new thread as people may find this of interest.
I measured power consumptiion of on of my sytems running a small number of different configurations it may be of interest. The mearuring device is currently availble cheaply but has been checked against a known accurate power meter and found to be almost spot on.
The system is essentialy a 3D gaming and game development system, bye the way, the figures given here I find to be typical for this type of system.
The system even in hot weather does NOT in any way get much more than warm........ GOOD!!!
Description of system
Case Corsair 800D
PSU Corsair HX-650
MB ASUS P6X58D Premium
CPU Intel i7 950 at 3.0Ghz (not over clocked)
Memory 12 Gbytes
Graphics card ATI Radeon HD5870
Power consumption
1. sitting on bios screen 140w
Windows XP pro service pack 3
2. no apps running 142w
3. Openrails V0.7 (3D train simulator) 260-307w
Linux Debian 6.0.1 Custom kernel 2.6.39.4 open source radeon driver
4. sitting at LILO prompt 200w
5. running Xserver, window manager fvwm 207w
6. Xine viewing 1920x1080 H264 video 214-222w
Note item 4, this is the LILO prompt BEFORE the kernel has started,Windows manages to get the power down to the bios level, even the Linux boot system does not manage this.
Item 3, power consumpion varied for no dicernable reason, did not vary with frame rate or object density on the screen although power does increase with increased cpu usage.
Also, the H264 video is being decoded by the cpu taking aprox 30% of a single cpu the power this takes is only 16w.
With the monitor the power consumed is close to 250 watts, this means 1 dollar Australian will run the system for around 10 hours.
I find it curious that windows gets the power down almost to the bios level whereas even the Linux boot program does not acheive this. So one assumes Microsoft must have gone to some lengths to get the power consumption down.
