Electricity consumption o. m. rig

Funny avatar you got!

The measurement was taken from the computer + a printer in standby + a connected tv-stick (very hot) + a connected webcam + a backlights having keyboard + a mouse + the true flat trinitron CRT.

this concerns me, if it is very hot then you are drawing too much power through it or it is defective and overheating. you should look at fixing this before it gets worse and you have it start melting on you.

electrical plugs, outlets, wires, or connections should never be hot, a little warm is ok but never hot.

I use the "Sleep" mode in Vista Start menu.
It would seem like it powers down everything except RAM as power consumption plummets to less than 20W measured from the wall outlet. Then just hit the power button and you're immediately back on desktop with everything up and running exactly like the moment you put it in sleep mode. And btw, a typical ATX PSU consumes 10-15W even when it's not actually turned on. I mean just as long as it's plugged in an wall outlet and the I/O switch on the unit is @ I.

This is what I do. All my 4 PCs have the same Power settings
Power Schemes: Portable/Laptop (So AMD C'n'Q will be effective. This will save me shit load on power consumption)
Monitor: Turn off in 5 minutes (All are LCD + one connected to TV)
HDD: Turn off in 10 min
Standby: 15 min.
No Hibernation.

When setting HDDs to power down after such a short time as 10 minutes of idling keep in mind powering up stresses the motor more than continuous spinning.

Pretty aggressive power savings. All my machines are in standby and pretty much consume may be around 10W/hr?

I gather you mean 10kWh a day?

10KWH a day - don't know.

I have more than one HDD on most of my machines. So powering down the HDDs thats not used is better than spinning them constantly. Ofcourse the OS HDD is going to be spinning continously until S3 state kicks in.

Even if the power costs only 0.046€ at daytime and 0.036€ at nighttime.. i cosume about 5KWH a day which is 5x12x0.046+5x12x0.036 which is like 5€ a day.. Am i confused or did i calculate right.

It goes like this:

Daytime (07:00-22:00):
kWh × €/kWh × (daytime/day)
5kWh × 0.046€/kWh × 0.625
= 0.14375€

Nigthtime (22:00-07:00):
kWh × €/kWh × (nighttime/day)
5kWh × 0.036€/kWh × 0.375
= 0.08625€

Total:
0.14375€ + 0.08625€
= 0.23€ a day

vistas sleep mode depends on your motherboard - it has to support intel ViiV or AMD AWAY. its also called S4 standby in one of my bioses.

I too use a wall meter, and thats why i have so many PC's now - its cheaper to say, have my 8x hard drives in my storage system turned off 90% of the time, than have em on gaming/web browsing.

Ok i am a bit confused then because i went to a higher mathematical technical school for 7 years.

I had a brain fart, my Kill-A-Watt (Model=P3) does indeed measure KWH!!! I didn't see it before. So I'm up to 0.03 KWH after about 10 min.

I'm measuring ONLY my CPU, been itching to put it into the main (monitor, sound, printer), but thats down by the floor and a tangled mess.

The CPU draws about 250w idle and around 360w gaming. If I run the automated clock utility in CCC, it goes up to 380+!

Now this is interesting: If I go into sleep mode, the CPU draw does not change! Anyone know what's up with that???

Sasqui,
Dunno what's going on but 250W idle appears somewhat high for a 3.5GHz E6600 + HD2900PRO compared to for example my 3.6GHz Q6600 + 8800GTS 512MB (800/2000/1050) combo which draws 170W when on Vista desktop and 300W while playing Crysis. Load can be explained by your video card but isn't HD2900PRO supposed to be on par to 8800GTS 512MB @ idle?

Good question... the clocks on the 2900 are at XT speeds, but only during gaming. There isn't anything else signigifcant to explain the difference. I keep the rig OFF when not in use for the power savings - even if it is a fraction of my 'fridge

You can save a lot by having the CPU power management set up. Cool'n'Quiet and Speedstep/C1E. These drop both CPU clock and voltage and it really reduces the power usage. It also helps to have an efficient video card like a GF8600 (or lower) or Radeon 38x0. 8800GTX pulls like 70W doing nothing, for example.

My Radeon 3850 draws as much at idle as the 8600GT I used to use. That's fairly amazing to say the least.

Hard drives are nothing. They each use like 8W or so when idling. Fans use even less (probably 2-3W unless you have a 3000 RPM 120mm hair drier or somethin).
