Idle power consumtion

I don't know it this is the right place to ask this, sorry if I should have posted elsewhere.

So I was just wondering how much power my PC is using during idle(listening to music, reading news/forums). But I couldn't find a site where you just insert your parts and it gives you an approximation, like the ones that tell you the PSU you need.

My questions are: is there such a site? if not, is it just a mater of adding the numbers, and then, are there any hidden heavy power consuming chips in the PC that I wouldn't know about if I were to calculate the power consumption myself, like north bridge or something else? I have activated Cool'n'quiet.


Any help is appreciated.

MoBo: Asus M4A77T
Proc: Phenom ii x2 550
DDR3: 4GB (2x2GB) OCZ low voltage 1333Mhz
Graphics: Ati HD5750 by XFX
HDD: WD 500GB
PSU: 400W OCZ silent

Listening to music and some forum activity isnt perfectly idle.

Even idle, the graphics card is a big part of the power consumption. The rest of your PC is pretty consistent based on the CPU and any voltage increases from overclocking.

The thing that I really don't know is if the Thermal Design power for my cpu is 80W then how much does it consume on idle? Where can I find something like this out? is it 40W, is it 20W or is it 5W? an estimate is what I need.

I know my GPU is supposed to only take like 16W on idle.

They almost always give idle and load wattages in the articles section for the computers they test.

The $550 computer in this article has a similar CPU/motherboard and GPU (athon II x3, Asus M4A77TD, 5770)
It runs around 100 watts "idle" and 250 under CPU and GPU load.

thanks, I reached the same conclusion after looking at some articles, my pc must be using about 100W in idle. A bit high in my opinion compared to a notebook, I would have expected with all the Cool&quiet and reduced cpu ratio when idleing the power consumption to be somewhere very low, like 40W. Anyway, thanks.
