Read carefully:
I want to see the overall power usage (in watts) of a basic 1155 system (Including motherboard, memory, power supply and processor), minus the graphics card (so you will have to use the on board graphics) idling in Windows.

Can some of you guys try this? I'm very interested in i3 and i5 chips in particular.

You will need a gizmo like this to check the results, so I am pretty much banking on you guys having one lying around.

I cant do it myself since I have 1st gen i5 with no on board graphics. And if you are wondering why I want this, I am building a server that needs low power consumption but high performance at same time.

My system with the HD 5870 running uses 67 W from the wall. (With CPU @ stock, not using my overclock)

Going by this, the card uses 16 W on idle.

67 - 18W (assuming approx 85% efficency) = 49 W
+ say 5 W for an onboard graphics = 54 W

On idle you'd expect the i5 2500k @ stock to be about the same.

My PSU is pretty good, but at low power it's probably around 85% efficiency, so output would be around 46 W.
 
I would like it to be verified from a power measurement device as pictured on OP (though can be any make/model of course!) with no graphics card, only on board graphics. 67w is pretty good for a 2600k with a card in it, I would like to see if it can be beat in other peoples i3/i5 rigs.

Unfortunately my mobo is a P67 Chipset so I can't do it myself, would expect it to be in the 50-55 W zone. Remember different mobos and chipsets could make a big difference too.

Based on 10p per kWh my PC @ 67 W idle for 24/7 for a year would cost £58.69. (£43.80 if I got it down to 50 W)

The i3 @ 22 W for a year would cost £19.27.

I think its mainly down to the power regs and not the chipset.
